That's a beautiful way of seeing how I view life. It's odd for me to say "I pray to life" as it makes Life a noun-object/person/or place even of devotion. Life is much more than a focal point of worship but we are within life and living is worship and prayer in and of itself. That said...
That is my question for you friends: what causes the mystery to be called god, and people to attach all these human terms and conceptions to the unfathomable?
Calling the mystery Tao, God, Buddha-nature (Buddha), Holy Spirit, Spirit, Universe, and so forth are all different means that maybe humans need to relate to something they are completely unfamiliar with. I think it's more of a convenience that people adopt or are indoctrinated in a personal way because it gives a means of conversation and worship with something they want to, not allowed to, or can't find the means to name.
While I understand that the mystery is not named and it makes it "greater" by that definition, in my point of view, there is nothing greater. So, however or whatever name we use to define the mystery isn't wrong. It's a human means of finding a connection with the unknown. So, in other words, naming doesn't mean we are defining something correctly-just for our purpose of relationship with the mystery not dictating what the mystery is.
That, and I've never been a "human terms are not appropriate" or "those are man's terms and they are limited" etc. My religion involves my art from creative expression, poetry, art, etc and using words, body language, etc are beautiful ways to depict life. When we say "human concepts are limited" we separate ourselves from the mystery (or god) rather than being part of god. How can you be a part of god when you make him your authority rather than your friend?
So, people do so for many reasons. It's easier to connect when there is a focal point of language. Some people like myself have more a creative way of connecting to the mystery by the words we use, the dances, and things we draw etc. While others just avoid naming the mystery all together. Which is odd, since we are a part of the mystery and yet we name ourselves and the environment around us.
Even the word Tao itself is attempting to name the mystery. I don't find that wrong. I'd just say every name has it's place but not so distinct to say it
does define the mystery. If it does, it wouldn't be a mystery.
