Our samskaras, or the accumulation of habits formed from past action and thought, are deep impressions that have dug themselves into our mind-body system. These samskaras manifest in the form of bracing. We tighten in our mind-body in order to push away unpleasantness or to grab at the desirable. It is this contraction that creates the illusion of separation. By bringing our awareness to these deep holdings, they begin to loosen on their own, returning to their natural state. We stop bracing against the world.
