Of course you can. Spirituality is free, you can find it anywhere. At the park, in the arms of a lover, at your job. There are as many ways to be spiritual as there are spiritual people. In my view, you don’t even have to believe in God to be spiritual. Spirituality concerns the transcendent, transcendence is literally everywhere, I consider reverence for art to be a form of spirituality.
Even in religious / spiritual communities you find that everyone has their own way of going about things. After talking to a lot of these sorts of people, I’ve come to understand that a person’s creed matters about as much as the color of their shoes. Plenty of really wise, deeply intuitive people of the cloth out there. Also plenty in the pews. Also plenty who stay home on Sundays. Also plenty who never even heard of church. Plenty whose idea of spirit involves knives and altars. Plenty who deny the existence of the transcendent at all and call themselves atheist.
