 Brahma is the force of creation in the universe. He is called the father of fathers, the golden fetus, or the architect of the universe. Brahma isn't worshipped so much today, though. The idea is that he created everything and then left the rest to the other two. There's also some mythology where he screwed up a bit and got one of his five heads cut off and is still in the process of redeeming himself, though it is said that the time of Brahma is coming again soon.
