Rumi said, There is no proof of the soul.
But isn't the return of spring and how it
springs up in our hearts a pretty good hint?
The secret of seeing is...the pearl of great price...But although the pearl may be found, it may not be sought...although it comes to those who wait for it, it is always, even to the most practiced and adept, a gift and a total surprise....I cannot cause light; the most I can do is try to put myself in the path of its beam. It is possible, in deep space, to sail on solar wind. Light, be it particle or wave, has force: you rig a giant sail and go. The secret of seeing is to sail on solar wind. Hone and spread your spirit till you yourself are a sail, whetted, translucent...
~ Annie Dillard in PILGRIM AT TINKER CREEK
