The meaning I like is the simple one of awareness of inter-connectedness
I really like a Simone Weil quote: “Attention, taken to its highest degree, is the same thing as prayer. It presupposes faith and love. Absolutely unmixed attention is prayer.”
Spirituality being a practice of choosing what to pay attention to.
And a practice of trying to subvert the illusion of self. That’s why acid helps, as a technology of non-self, as does rave, meditation etc. Also in this sense, Marxism is not opposed to spirituality at all, and class consciousness is a spiritual idea
Any sense of an abstract ‘immaterial’ world doesn’t make any sense to me. Everything is material. This is monism probably. Spinoza.
Kpunk was good on this materialist spirituality:
“Spinoza’s God is beyond even indifference, gloriously, desolately without interests of any kind. Intellectual love of God is effectively an identification with the cosmos as BwO. Spinoza’s conviction that awe, wonder and dread - not worship - are the only appropriate responses to a God that is the Great Zero, means that his thought can offer us a pitilessly materialist spirituality that is as important a legacy as anything else he has left us.”
