What if you let go of every bit of control and every urge that you have, right down to the most infinitesimal urge to control anything, anywhere, including anything that may be happening with you at this moment? If you were able to give up control absolutely, totally, and completely, then you would be a spiritually free being.
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.
The press is like a woman: sublime when it lies, it will not let go until it has forced you to believe it. The public, like a foolish husband, always succumbs.
