"Nonattachment is, of course, what we are practicing when we meditate.
Because the self is composed of mostly habitual ways of thinking, feeling, acting, reacting and so forth, it means that when I "let go" of them while meditating, I am deconstructing my sense of self - or, more precisely, the self is deconstructing, because it is not really something that "I" can do."
