The Kuzari [1/109] says that Dveykus [clinigng to G-d] is expressed in Prophecy and seeing the hand of Hashem in the world.
109. The Rabbi: Now all that our promises [יעודנו] imply is that we shall become connected with the divine influence [הידבקנו בענין הא-להי] by means of prophecy, or something nearly approaching it, and also through our relation to the divine influence, as displayed to us in grand and awe-inspiring miracles. Therefore we do not find in the Bible: 'If you keep this law, I will bring you after death into beautiful gardens and great pleasures.' On the contrary it is said: 'You shall be my chosen people, and I will be a God unto you, who will guide you. Whoever of you comes to me, and ascends to heaven, is as those who, themselves, dwell among the angels, and my angels shall dwell among them on earth. You shall see them singly or in hosts, watching you and fighting for you without your joining in the fight. You shall remain in the country which forms a stepping-stone to this degree, viz. the Holy Land. Its fertility or barrenness, its happiness or misfortune, depend upon the divine influence which your conduct will merit, whilst the rest of the world would continue its natural course. For if the divine presence is among you, you will perceive by the fertility of your country, by the regularity with which your rainfalls appear in their due seasons, by your victories over your enemies in spite of your inferior numbers, that your affairs are not managed by simple laws of nature, but by the divine Will. You also see that drought, death, and wild beasts pursue you as a result of disobedience, although the whole world lives in peace. This shows you that your concerns are arranged by a higher power than mere nature.'
The Rambam [Moreh Nevuchim 3/51] says that Dveykus is intellectual attainment:
THE present chapter does not contain any additional matter that has not been treated in the [previous] chapters of this treatise. It is a kind of conclusion, and at the same time it will explain in what manner those worship God who have obtained a true knowledge concerning God; it will direct them how to come to that worship, which is the highest aim man can attain, and show how God protects them in this world till they are removed to eternal life.
I will begin the subject of this chapter with a simile. A king is in his palace, and all his subjects are partly in the country, and partly abroad. Of the former, some have their backs turned towards the king's palace, and their faces in another direction; and some are desirous and zealous to go to the palace, seeking "to inquire in his temple," and to minister before him, but have not yet seen even the face of the wall of the house. Of those that desire to go to the palace, some reach it, and go round about in search of the entrance gate; others have passed through the gate, and walk about in the ante-chamber; and others have succeeded in entering into the inner part of the palace, and being in the same room with the king in the royal palace. But even the latter do not immediately on entering the palace see the king, or speak to him; for, after having entered the inner part of the palace, another effort is required before they can stand before the king--at a distance, or close by--hear his words, or speak to him. I will now explain the simile which I have made. The people who are abroad are all those that have no religion, neither one based on speculation nor one received by tradition. Such are the extreme Turks that wander about in the north, the Kushites who live in the south, and those in our country who are like these. I consider these as irrational beings, and not as human beings; they are below mankind, but above monkeys, since they have the form and shape of man, and a mental faculty above that of the monkey.
Those who are in the country, but have their backs turned towards the king's palace, are those who possess religion, belief, and thought, but happen to hold false doctrines, which they either adopted in consequence of great mistakes made in their own speculations, or received from others who misled them. Because of these doctrines they recede more and more from the royal palace the more they seem to proceed. These are worse than the first class, and under certain circumstances it may become necessary to day them, and to extirpate their doctrines, in order that others should not be misled.
Those who desire to arrive at the palace, and to enter it, but have never yet seen it, are the mass of religious people; the multitude that observe the divine commandments, but are ignorant. Those who arrive at the palace, but go round about it, are those who devote themselves exclusively to the study of the practical law; they believe traditionally in true principles of faith, and learn the practical worship of God, but are not trained in philosophical treatment of the principles of the Law, and do not endeavour to establish the truth of their faith by proof. Those who undertake to investigate the principles of religion, have come into the ante-chamber; and there is no doubt that these can also be divided into different grades. But those who have succeeded in finding a proof for everything that can be proved, who have a true knowledge of God, so far as a true knowledge can be attained, and are near the truth, wherever an approach to the truth is possible, they have reached the goal, and are in the palace in which the king lives.
My son, so long as you are engaged in studying the Mathematical Sciences and Logic, you belong to those who go round about the palace in search of the gate. Thus our Sages figuratively use the phrase: "Ben-zoma is still outside." When you understand Physics, you have entered the hall; and when, after completing the study of Natural Philosophy, you master Metaphysics, you have entered the innermost court, and are with the king in the same palace. You have attained the degree of the wise men, who include men of different grades of perfection. There are some who direct all their mind toward the attainment of perfection in Metaphysics, devote themselves entirely to God, exclude from their thought every other thing, and employ all their intellectual faculties in the study of the Universe, in order to derive therefrom a proof for the existence of God, and to learn in every possible way how God rules all things; they form the class of those who have entered the palace, namely, the class of prophets. One of these has attained so much knowledge, and has concentrated his thoughts to such an extent in the idea of God, that it could be said of him, "And he was with the Lord forty days," etc. (Exod. xxxiv. 28); during that holy communion he could ask Him, answer Him, speak to Him, and be addressed by Him, enjoying beatitude in that which he had obtained to such a degree that "he did neither eat bread nor drink water" (ibid.); his intellectual energy was so predominant that all coarser functions of the body, especially those connected with the sense of touch, were in abeyance. Some prophets are only able to see, and of these some approach near and see, whilst others see from a distance: comp. "The Lord hath appeared from far unto me" (Jer. xxxi, 3). We have already spoken of the various degrees of prophets; we will therefore return to the subject of this chapter, and exhort those who have attained a knowledge of God, to concentrate all their thoughts in God. This is the worship peculiar to those who have acquired a knowledge of the highest truths; and the more they reflect on Him, and think of Him, the more are they engaged in His worship. Those, however, who think of God, and frequently mention His name, without any correct notion of Him, but merely following some imagination, or some theory received from another person, are, in my opinion, like those who remain outside the palace and distant from it. They do not mention the name of God in truth, nor do they reflect on it. That which they imagine and mention does not correspond to any being in existence: it is a thing invented by their imagination, as has been shown by us in our discussion on the Divine Attributes (Part I. chap. 1.). The true worship of God is only possible when correct notions of Him have previously been conceived. When you have arrived by way of intellectual research at a knowledge of God and His works, then commence to devote yourselves to Him, try to approach Him and strengthen the intellect, which is the link that joins you to Him. Thus Scripture says, "Unto thee it was showed, that thou mightest know that the Lord He is God" (Deut. iv. 35); "Know therefore this day, and consider it in thine heart, that the Lord He is God" (ibid. 36); "Know ye that the Lord is God" (Ps. c. 3). Thus the Law distinctly states that the highest kind of worship to which we refer in this chapter, is only possible after the acquisition of the knowledge of God. For it is said, "To love the Lord your God, and to serve Him with all your heart and with all your soul" (Deut. xi. 13), and, as we have shown several times, man's love of God is identical with His knowledge of Him. The Divine service enjoined in these words must, accordingly, be preceded by the love of God. Our Sages have pointed out to us that it is a service in the heart, which explanation I understand to mean this: man concentrates all his thoughts on the First Intellect, and is absorbed in these thoughts as much as possible. David therefore commands his son Solomon these two things, and exhorts him earnestly to do them: to acquire a true knowledge of God, and to be earnest in His service after that knowledge has been acquired. For he says, "And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart . . . if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever" (1 Chron. xxviii. 9). The exhortation refers to, the intellectual conceptions, not to the imaginations: for the latter are not called "knowledge," but "that which cometh into your mind" (Ezek. xx. 32). It has thus been shown that it must be man's aim, after having acquired the knowledge of God, to deliver himself up to Him, and to have his heart constantly filled with longing after Him. He accomplishes this generally by seclusion and retirement. Every pious man should therefore seek retirement and seclusion, and should only in case of necessity associate with others.
Note.--I have shown you that the intellect which emanates from God unto us is the link that joins us to God. You have it in your power to strengthen that bond, if you choose to do so, or to weaken it gradually, till it breaks if you prefer this. It will only become strong when you employ it in the love of God, and seek that love: it will be weakened when you direct your thoughts to other things. You must know that even if you were the wisest man in respect to the true knowledge of God, you break the bond between you and God whenever you turn entirely your thoughts to the necessary food or any necessary business; you are then not with God, and He is not with you: for that relation between you and Him is actually interrupted in those moments. The pious were therefore particular to restrict the time in which they could not meditate upon the name of God, and cautioned others about it, saying, "Let not your minds be vacant from reflections upon God." In the same sense did David say, "I have set the Lord always before me; because he is at my right hand, I shall not be moved" (Ps. xvi. 8); i.e., I do not turn my thoughts away from God; He is like my right hand, which I do not forget even for a moment on account of the ease of its motions, and therefore I shall not be moved, I shall not fail.
We must bear in mind that all such religious acts as reading the Law, praying, and the performance of other precepts, serve exclusively as the means of causing us to occupy and fill our mind with the precepts of God, and free it from worldly business; for we are thus, as it were, in communication with God, and undisturbed by any other thing. If we, however, pray with the motion of our lips, and our face toward the wall, but at the same time think of our business; if we read the Law with our tongue, whilst our heart is occupied with the building of our house, and we do not think of what we are reading; if we perform the commandments only with our limbs, we are like those who are engaged in digging in the ground, or hewing wood in the forest, without reflecting on the nature of those acts, or by whom they are commanded, or what is their object. We must not imagine that [in this way] we attain the highest perfection; on the contrary, we are then like those in reference to whom Scripture says, "Thou art near in their mouth, and far from their reins" (Jer. xii. 2).
The Rambam [Igeres Tchiyas Hameisim p. 370] says that part of being close to Hashem is observing His hashgacha. But he writes [Moreh Nevuchim 3/17-18] that one has hashgacha to the extent that he has acheived intellectual attainment. The more one understands and is close to Hashem - the greater the hashgacha:
My opinion on this principle of Divine Providence I will now explain to you. In the principle which I now proceed to expound I do not rely on demonstrative proof, but on my conception of the spirit of the Divine Law, and the writings of the Prophets. The principle which I accept is far less open to objections, and is more reasonable than the opinions mentioned before. It is this: In the lower or sublunary portion of the Universe Divine Providence does not extend to the individual members of species except in the case of mankind. It is only in this species that the incidents in the existence of the individual beings, their good and evil fortunes, are the result of justice, in accordance with the words, "For all His ways are judgment." But I agree with Aristotle as regards all other living beings, and à fortiori as regards plants and all the rest of earthly creatures. For I do not believe that it is through the interference of Divine Providence that a certain leaf drops [from a tree], nor do I hold that when a certain spider catches a certain fly, that this is the direct result of a special decree and will of God in that moment; it is not by a particular Divine decree that the spittle of a certain person moved, fell on a certain gnat in a certain place, and killed it; nor is it by the direct will of God that a certain fish catches and swallows a certain worm on the surface of the water. In all these cases the action is, according to my opinion, entirely due to chance, as taught by Aristotle. Divine Providence is connected with Divine intellectual influence, and the same beings which are benefited by the latter so as to become intellectual, and to comprehend things comprehensible to rational beings, are also under the control of Divine Providence, which examines all their deeds in order to reward or punish them. It may be by mere chance that a ship goes down with all her contents, as in the above-mentioned instance, or the roof of a house falls upon those within; but it is not due to chance, according to our view, that in the one instance the men went into the ship, or remained in the house in the other instance: it is due to the will of God, and is in accordance with the justice of His judgments, the method of which our mind is incapable of understanding. I have been induced to accept this theory by the circumstance that I have not met in any of the prophetical books with a description of God's Providence otherwise than in relation to human beings. The prophets even express their surprise that God should take notice of man, who is too little and too unimportant to be worthy of the attention of the Creator: how, then, should other living creatures be considered as proper objects for Divine Providence! Comp. "What is man, that thou takest knowledge of him?" (Ps. cxliv. 3); "What is man, that thou art mindful of him?" (ibid. viii. 8). It is clearly expressed in many Scriptural passages that God provides for all men, and controls all their deeds--e.g., "He fashioneth their hearts alike, he considereth all their works" (ibid. xxxiii. 15); "For thine eyes are open upon all the ways of the sons of men, to give every one according to his ways" (Jer. xxxii. 19). Again: "For his eyes are upon the ways of man, and he seeth all his goings" (Job xxxii. 21). In the Law there occur instances of the fact that men are governed by God, and that their actions are examined by him. Comp. "In the day when I visit I will visit their sin upon them" (Exod. xxxii. 34) "I will even appoint over you terror" (Lev. xxvi. 16); "Whosoever hath sinned against me, him will I blot out of my book" (Exod. xxxii. 33); "The same soul will I destroy" (Lev. xxiii. 30); "I will even set my face against that soul" (ibid. xx. 6). There are many instances of this kind. All that is mentioned of the history of Abraham, Isaac, and Jacob is a perfect proof that Divine Providence extends. to every man individually. But the condition of the individual beings of other living creatures is undoubtedly the same as has been stated by Aristotle. On that account it is allowed, even commanded, to kill animals; we are permitted to use them according to our pleasure.
HAVING shown in the preceding chapter that of all living beings mankind alone is directly under the control of Divine Providence, I will now add the following remarks: It is an established fact that species have no existence except in our own minds. Species and other classes are merely ideas formed in our minds, whilst everything in real existence is an individual object, or an aggregate of individual objects. This being granted, it must further be admitted that the result of the existing Divine influence, that reaches mankind through the human intellect, is identical with individual intellects really in existence, with which, e.g., Zeiḍ, Amr, Kaled and Bekr, are endowed. Hence it follows, in accordance with what I have mentioned in the preceding chapter, that the greater the share is which a person has obtained of this Divine influence, on account of both his physical predisposition and his training, the greater must also be the effect of Divine Providence upon him, for the action of Divine Providence is proportional to the endowment of intellect, as has been mentioned above. The relation of Divine Providence is therefore not the same to all men; the greater the human perfection a person has attained, the greater the benefit he derives from Divine Providence. This benefit is very great in the case of prophets, and varies according to the degree of their prophetic faculty: as it varies in the case of pious and good men according to their piety and uprightness. For it is the intensity of the Divine intellectual influence that has inspired the prophets, guided the good in their actions, and perfected the wisdom of the pious. In the same proportion as ignorant and disobedient persons are deficient in that Divine influence, their condition is inferior, and their rank equal to that of irrational beings: and they are "like unto the beasts" (Ps. xlix. 21). For this reason it was not only considered a light thing to slay them, but it was even directly commanded for the benefit of mankind. This belief that God provides for every individual human being in accordance with his merits is one of the fundamental principles on which the Law is founded.
Consider how the action of Divine Providence is described in reference to every incident in the lives of the patriarchs, to their occupations, and even to their passions, and how God promised to direct His attention to them. Thus God said to Abraham, "I am thy shield" (Gen. xv. 1); to Isaac, "I will be with thee, and I will bless thee" (ibid. xxvi. 3); to Jacob, "I am with thee, and will keep thee" (ibid. xxviii. 15); to [Moses] the chief of the Prophets, "Certainly I will be with thee, and this shall be a token unto thee" (Exod. iii. 12); to Joshua, "As I was with Moses, so I shall be with thee" (Josh. i. 5). It is clear that in all these cases the action of Providence has been proportional to man's perfection. The following verse describes how Providence protects good and pious men, and abandons fools; "He Will keep the feet of his saints, and the wicked shall be silent in darkness; for by strength shall no man prevail" (1 Sam. ii. 9). When we see that some men escape plagues and mishaps, whilst others perish by them, we must not attribute this to a difference in the properties of their bodies, or in their physical constitution, "for by strength shall no man prevail"; but it must be attributed to their different degrees of perfection, some approaching God, whilst others moving away from Him. Those who approach Him are best protected, and "He will keep the feet of his saints"; but those who keep far away from Him are left exposed to what may befall them; there is nothing that could protect them from what might happen; they are like those who walk in darkness, and are certain to stumble. The protection of the pious by Providence is also expressed in the following passages:--"He keepeth all his bones," etc. (Ps. xxxiv. 21); "The eyes of the Lord are upon the righteous" (ibid. ver. 16); "He shall call upon me and I shall answer him" (ibid. ver. 15). There are in Scripture many more passages expressing the principle that men enjoy Divine protection in proportion to their perfection and piety. The philosophers have likewise discussed this subject. Abu-nasr, in the Introduction to his Commentary on Aristotle's Nikomachean Ethics, says as follows:--Those who possess the faculty of raising their souls from virtue to virtue obtain, according to Plato, Divine protection to a higher degree.
Now consider how by this method of reasoning we have arrived at the truth taught by the Prophets, that every person has his individual share of Divine Providence in proportion to his perfection. For philosophical research leads to this conclusion, if we assume, as has been mentioned above, that Divine Providence is in each case proportional to the person's intellectual development. It is wrong to say that Divine Providence extends only to the species, and not to individual beings, as some of the philosophers teach. For only individual beings have real existence, and individual beings are endowed with Divine Intellect; Divine Providence acts, therefore, upon these individual beings.
