Relaxation is one of the most complex phenomena - very rich, multidimensional. All these things are part of it: let-go, trust, surrender, love, acceptance, going with the flow, union with existence, egolessness, ecstasy. All these are part of it, and all these start happening if you learn the ways of relaxation.
But the disappearance of the effort to let go is precisely the disappearance of the separate thinker, of the ego trying to watch the mind without interfering.

Let go of the idea that the path will lead you to your goal. The truth is that with each step we take, we arrive. Repeat that to yourself every morning: 'I've arrived.' That way you'll find it much easier to stay in touch with each second of your day.
