Meditation provides one with the ability to choose; to look at what is arising and decide "yes I want to work with this," or "no, it is not necessary to work with this." I experience this when I suffer from insomnia, where thoughts are churning out virally and preventing sleep. In learning this type of discernment we free up vast quantities of energy that allows our mind to function more efficiently and to naturally be more easeful. In this sense, it gives our experiences more space, more of a balanced context from which we can perceive emotions, thoughts, and feelings for what they really are. It also supports us to see what we need (if anything) from this patterned unfolding of the vibration (or the vritti).
