I've been wondering about this for a while, and find it unclear whether my spiritual side is simply "not actually religion".

I wonder if you could clarify for me what you mean by "spiritual" in "spiritual side"? I was raised as a Roman Catholic, and to me 'spiritual' means the other side of Descartes's dualism - the non-physical side. So, for example, I learned that the Deity and angels are purely spiritual. But being human, my spiritual side is my immortal soul - which pretty much includes my mind.

I'm pretty sure you (and millions of other people who talk about spirituality) mean something different from this, but I have never been able to figure out what you all mean.

A definition of 'spiritual' is preferred, but failing that, could you taboo 'spiritual' and say what you meant by 'spiritual side' without using the word?
