Maybe Temple is not a good word. It's connection to religion. Worship. Not my thing. In any form.
Somewhere along the way, I was told, never talk about God, it will drive people away. I never take advice. Know me, I say.
But, so, connection to something outside one's self. The bigger, even if it is simply a kind of respect, acknowledgement of the smallness of self, I think temple can be used like that. Not sacred space but a sense of being held by that which we cannot know, building a window into that. Making place. A field of peace of mind.
