There are two ways of resolving points of doubt in learning.
1] Finding one strong, incontrovertible proof.
2] Finding numerous hints that might not explicitly resolve the doubt but certainly point one in the direction of truth.
The advantage of the former is that the proof is clear and cogent while the advantage of the latter is that the numerous hints one sees serve to drive the point home with more emphasis.
NOW, we can understand the famous beginning of the Messilas Yesharim, where it says that the obligation of every Jew is "she'yisbarrer vi'yisameis aitzel ha'odom mah chovaso ba'olamo" - to clarify and find the truth revealing your obligation in this world. Many of our spiritual titans have tried to understand the difference between "yisbarrer" and "yisameis". Yisbarrer is that it should become clear through one proof what your purpose in this world is. "Yisameis" is to find many hints in your life until this truth penetrates to the core of your soul.

People spend much time reading the sports pages and finding out what is going on in Washington - and in China, but are ignorant as to the purpose of their own existence. This requires much soul-searching and introspection.
But what's an Elul for?!
