Lord Buddha never spoke about God because India was the land where everybody knew so much about spirituality, but mostly it was all in the head. So Lord Buddha used to announce the eleven questions that he would not answer. Eleven questions should not be asked, and even if someone asked him, he would not answer. God was one of the eleven questions.
He simply said that there is misery in life, but it is possible to get rid of misery because there is a cause for misery.
One guy came he said, "I believe in God, what do you say?" So Buddha said, "You believe in God, okay, good".
Another person said, "I don't believe in God, there is no God", and Buddha said, "Okay, good".
A third person came and he said, "Some people say there is God and some people say there is no God. I don't know but I want to know".
A third person came and he said, "Some people say there is God and some people say there is no God. I don't know but I want to know".
Then Buddha said, "Oh okay, you come be here and we will discover".
So other disciples who were there got so confused because Buddha agreed with everybody. When they asked him, he said, "You know, the first two people who came had a fixed idea in their mind, they were not open. But the last one was open to knowing and he can reach enlightenment. It's hard for people with fixed ideas to get enlightened". So that's the story.
