Plato, in his Cave Allegory, taught that the sun of awakening rises high above the murky depths of ignorance. His peers, the authors of the Upanishads, held rather that the shining sun of the Self lies hidden in the innermost cavern of the heart. As far as I can tell, the Upanishads had it right. It is precisely those who insist on seeing by the clear light of day who end up knowing least. Coming to know requires an ever deeper exploration of the self's, of the world's, many shadow-strewn ways.
