Seeking to understand the genesis and, especially, the original function of vexatious brain-mind clusters leads us to the first principle of compassionate self-inquiry. Everything within us, no matter how distressing, exists for a purpose; there is nothing that shouldn’t be there, troublesome and even debilitating though it may be. The question thus shifts from “How do I get rid of this?” to “What is this for? Why is this here?” In other words, we endeavor first to get to know these irksome aspects of ourselves and then, as best we can, to turn them from foes to friends.
