Suffering is far more simple. Suffering arises due to ignorance. Suffering is self-created and self-inflicted in ignorance and misunderstanding.
While suffering, by and large, ceases when the illusion of "me" shatters...suffering really does not cease by the belief that All is 'Itself' (One), and the capacity to resonate with, have faith, or trust in, that belief. It is not about belief, but profound, direct understanding. Understanding arises when you see...like when people say, "oh, I see." So look deeply at suffering (and the roots and sources of suffering) and understand it. Better yet, look deeply at the "me" and understand it.
