Great excerpt.
I also like this essay by Daniel Ingram, which helps put that in perspective.
Why the notion you cannot become what you already are is such bullshitAn excerpt:
Why The Notion That You Cannot Become What You Already Are is Such Bullshit:
This notion encourages people to not practice. You can say what you like, but again and again I see people who subscribe to this and similar notions resting on their cleverness and grand posteriors and not actually getting it in the same way that my accomplished meditator friends get it. It seems so comforting, this notion that you are already something that you, in fact, are not. This brings us to the question of what you are and are not.
[...]
I have no idea where you are getting this bizarre notion, except that perhaps you are reading The Power of Now, following Adiashanti, or some other tradition that for reasons completely beyond me assumes that everyone already has the powers of perception of the rarest perceptual superstars.
I myself have known before and after, meaning that I know what I was capable of perceiving and understanding before I underwent meditative training and after, and no amount of being fed the concept that I was already as developed as I could be, was already enlightened, was already there, had nothing to do, nothing to develop, was already as clear as I could be, was already perfectly awake, etc. was going to make the difference that the thousands of hours over years of increasing my ability to perceive things clearly did.
