"The pain that you create now is always some form of nonacceptance, some form of unconscious resistance to what is. On the level of thought, the resistance is some form of judgment. On the emotional level, it is some form of negativity. The intensity of the pain depends on the degree of resistance to the present moment, and this in turn depends on how strongly you are identified with your mind."
When you feel pain over a certain reality or circumstance it is mostly because you don't accept this reality or circumstance as being to your benefit. Accept it as the absolutely BEST thing for yourself [as we believe it is and כל מה דעביד רחמנא לטב עביד] and the pain will disappear.
We also resist because we judge. We decide "This is NOT the right thing for me". Who am I to judge what is right and what is wrong??
We are also negative. We tell ourselves "This is bad". That is negativity rearing its ugly head.
Accept your reality as PERFECT for the present time and find yourself experiencing momentary bliss.
Jews call it "Emunah".
