Strange Drawing

A week ago, one of my Brazilian online buddies sent me this picture saying that he had drawn it while he was in a trance... don't know if he was meditating or was on pot or something ... he wanted me to check it out and interpret its meaning ... he figured out that since i'm Indian i'm supposed to know this cryptic stuff (stereotype eh?)...

The only interpretation i seem to make is that it has something to do with birth ... the four legged spiders don't make much sense ... does anyone recognize those symbols ???
