Talking about 'God' does not mean talking about overly religious topics. 

Almost any topic, can be considered in relation to the underlying spiritual reality. It's not as much what we talk about as how we talk about it, that matters.

It's not necessary to use such words as "God," "Spirit," "prayer," etc., at all. We might do better to remember that all of us are searching, however confusedly, for meaning in life and we welcome discussions about that meaning, provided we can find a common vocabulary.

Words are only symbols, and sometimes even barriers between us.
