yoga schmoga

I don't feel as flippant towards yoga as "yoga schmoga" would suggest as a title. its just that i took a yoga class yesterday and it was, as i expected it to be, a little new age-y. the thing is, it took place in the upstairs room of a church i thought to be christian, but could have been unitarian, which explains it. now, while im always a little weary of participating in things that are all about spiritualism and healing outside of christianity, i try to make all the meditation and "centering" into a time of prayer and just relaxing in a thankful-to-god manner.
anyway, we were in the middle of a relaxing period at the end of the session, complete with lilac-scented eye pillows, and the instructor read an excerpt from a book on wisdom. I dont remember every part she read, but i do remember, at one point, she read "you should learn from the wisdom of a tree..." and i started thinking. a tree? really? thats where we should get wisdom? not that yogi's derive wisdom solely from trees, but they also look within themselves, to nature, etc, to find this wisdom. and i couldnt help but think that these things are wrong because this is wisdom being sought from created things, and not from the creator.
the more problematic of these sources of knowledge, out of nature and humans, is, i think humans. the idea the humans could have buried inside themselves a perfectly enlightened, unlimited source of wisdom is absolutely impossible to me. of course, as a believer in god, i am biased because nothing could be higher than god. but there is enough proof in humanity alone to disprove our wisdom- think about all the mistakes people make, and how evil they can be, and how unreflective people can be about themselves. we are so limited- we DIE. we don't use 90% of our brain mass. we are, forever and ever, flawed. so i just dont really understand how one could come to the conclusion that if we go far enough INWARD, we will reach something further away from ourselves.
instead, we should be looking outside of ourselves, to something wholly removed and other than us. That is what the idea of "holiness" is. Not that i can do it justice, because i couldnt even begin to wrap my mind around a concept like holiness; but its the idea of a separation, being so perfect as to be set apart. So god is so far removed and so set apart from us, that he remains unscathed by anything human. furthermore, as the creator, doesnt it make sense for created things to look to their maker for wisdom?
just a thought.
