As my perception evolves, it is becoming clear to me that the path is never to discard anything, but rather to grow beyond it. In my view, no person can claim to be spiritual who does not understand nihilists, Satanists, hedonists, cynics, and everyone else who cannot make this world make sense for them within anything approaching a healthy paradigm. There is so much that all of us cannot see. Learning is a process of seeing blindness. We live within layer upon layer of not-seeing.
If I might paraphrase and mildly amend the Tao Te Ching, though, those who know they can’t see are not quite as blind. Or, as some Sufis put it, learning begins with learning how to learn.
