Buddha himself taught different teachings to different people under different circumstances. For some people, there are beliefs based on a Creator. For others, no Creator. The only "definitive truth" for Buddhism is the absolute negation of any one truth as the Definitive Truth.
Here's an example: someone says, "Master, please hand me the knife," and he hands them the knife, blade first. "Please give me the other end," he says. And the master replies, "What would you do with the other end?" This is answering an everyday matter in terms of the metaphysical. When the question is, "Master, what is the fundamental principle of Buddhism?" Then he replies, "There is enough breeze in this fan to keep me cool." That is answering the metaphysical in terms of the everyday, and that is, more or less, the principle zen works on. The mundane and the sacred are one and the same.
Oysters are more beautiful than any religion... There's nothing in Christianity or Buddhism that quite matches the sympathetic unselfishness of an oyster.
Buddhism ... is not a culture but a critique of culture, an enduring nonviolent revolution or "loyal opposition" to the culture in which it is involved.
I think when religions such as Hinduism and Buddhism - as well as Christianity and Judaism - were founded, at that time societies were generally male-dominated. So, therefore this social notion also influenced religion.
