Concept of Brahman

Well, i accidently just got off track with my posts and am a little behind. Anyways, today in class, there were some interesting things that were talked about and asked regarding Brahman. I feel that the concept that Brahman is everything is pretty cool, even though I am not Hindu. You can just imagine someone who has already attained the true belief of Brahman and seeing him/her as a different kind of person with a certain air to them. This is exactly what Professor Deitrick just stated also. Also, the question came up: "What would a person do afterwards after attaining the Atman or whatever it may be?" I think this is an interesting question because after a person attains that, do they get to be reincarnated? What would they be reincarnated into, even after attaining the true belief of Brahman? I think this aspect of Hinduism is complicated and it is expected that a multitude of questions would be asked about this concept.
