@JLNobody,
JL, you are correct in your assumption, at least in my case. I will say, that in my case, Buddhism is a behavior system I try to follow. The 4 basic truths, the 8 precepts, are simple truths that guide my behavior. They are not divine. They are simple facts. Truth revealed. Frank, you can call that a 'belief' if you wish, but it is an easily justified belief. And it is much more 'believable' to me than accepting a supreme being concept. It is also more useful, in my opinion. I don't say this out of criticism, just explaining my position.
I realize that is a pragmatic approach and that there is much more to Buddha's teaching. But that is why I continue to meditate and follow Buddha's teachings. Yes, there is some 'faith' necessary to continue study, but to me it is rational faith in a teacher, based upon past success. Not faith in some outside supreme being that may or may not exist.
So, we can argue about definition of belief or belief system, but it is clear to me at least that Buddhism is different. Buddha never said, 'believe in ME'. He said, 'listen to what I have to say and believe it'. There is a difference.
