I am not religious, but do feel spiritual in that I believe there is something bigger than us, and that we are part of a bigger, yet-unexplained whole that we reconnect with at some point. It is more of a "It's a comforting thought for me" thing rather than a set, unwavering surety. I don't really have any sort of practice of this, though. Lately I finally started meditating more - multiple times per week. I feel it helps to get me out of my head and closer to this sense of greater connection and wellbeing.
