What distinguishes surrender and self-inquiry from other techniques which focus on the breath, on a mantra, or on a particular object, is that they are processes of what I call progressive discernment. They are meant to help the seeker recognize what is thought, and, in that recognition, to detach from it. And as you recognize a particular thought, you are caught in another, which you may not even recognize you are caught up in. But through the process of surrender and self-inquiry, you do eventually recognize that that, too -- that strange, vague, feeling, conception, perception, or even silence -- is also a thought. And you recognize and detach from that. Through this process the bounds of thought are eventually and finally recognized and detached from... leaving only the unsayable Self.
