Over the course of nineteen essays, Alan Watts ("a spiritual polymatch, the first and possibly greatest" —Deepak Chopra) ruminates on the philosophy of nature, ecology, aesthetics, religion, and metaphysics.

Assembled in the form of a “mountain journal,” written during a retreat in the foothills of Mount Tamalpais, CA, Cloud-Hidden, Whereabouts Unknown is Watts’s meditation on the art of feeling out and following the watercourse way of nature, known in Chinese as the Tao. Embracing a form of contemplative meditation that allows us to stop analyzing our experiences and start living in to them, the book explores themes such as the natural world, established religion, race relations, karma and reincarnation, astrology and tantric yoga, the nature of ecstasy, and much more.
