I say physical journey rather than spiritual journey because I want to distance myself as much as possible from spirituality, because that is a loaded term which for me bears too much resemblance to religion. There is power in aesthetics, and though I may only reject the term spiritual on an aesthetic basis, I believe that this gives me sufficient linguistic distance that I can allow myself to believe that I have nothing to do with old ideas of spirituality religion so ingrained into me by existing in my current cultural context.
Spirituality of does not necessarily have to have anything to do with religion. Anything that you do that does not have an immediately observable and objective correlate outside of your own head is what I call spiritual. And it is fine and probably necessary for most humans to a certain extent to maintain such practices. The problem for me is the term, which I find to be ugly. It has been held for far too long by gurus of the new age and pompous priests of the middle ages, and they can have it. I want vital existence, which is in effect spirituality bent towards my will and personal understanding.
When I meditate I exist vitally. When I practice martial arts, play music, drink beer, fuck, perform well and intentionally at work, I am existing vitally. When existing vitally, there is no need for spirituality and the false dichotomy of spiritual/physical. There is in no demarcation line between the two except where it benefits the gatekeepers of the "spiritual". Where there is demarcation, it is only a meme generated by humans. Existence is the spirit and never stops, and my mission is to make it vital. When I die the reality that I created will continue on in those who I have irrevocably altered, and my remains too will be vital. I just wanted to make a death metal reference, and that was the point of this whole post, so take it with a mine of salt.
