While necessarily a nebulous concept unto itself, spirituality is a seeker’s creed: to suss Nature while being open to possibilities that reality may be more than what one can grasp; that the senses bring limited information; and that, fundamentally, things may not be what they seem. As such, rejecting action-is-essence existentialism, spirituality is a quest of questions, for answers that may not be forthcoming, or only partially disclosed. Wisdom is received.
The only real valuable thing is intuition. ~ Albert Einstein
In rejecting matterism as holding ultimate value, spirituality is a reach for revelations that may never cease, in an unending will to power for nothing more than understanding.
The possession of knowledge does not kill the sense of wonder and mystery. There is always more mystery. ~ Anaïs Nin
