How do you define something that is generally excepted as undefinable? That would be a great question.  Honestly, I would like to think that I have a good answer to this question but it would be so hard to try and put soemthing that is so huge on a minute scale.  If you try and define something then that makes it more real and on your level but God or Buddha or Allah or whatever is incredible and giant that taking it apart bit by bit would make it something that would be equal to any one of us so then there would be nothing "all powerful" or something like that to believe in.  Humans have an innate need to believe in something, even Atheists, if we didn't, life wouldn't be pretty.  So with that, I decline defining god because I find it to be impossible and honestly to be a very irrational thing to do because it could destroy belief, not religion, belief which is the very basis of our existence.  Incidently, if this makes no sense, I apologize, but I think I did a pretty good job.
