What is Buddhist metaphysics?

Answer 1

As we have said before, Buddha remained silent on metaphysical questions such as those of the origin of the world.

There has one sutta asking about metaphysical question that

In the Cula-Malunkyovada Sutta (Majjhima Nikaya 63), a monk named Malunkyaputta declared that if the Buddha did not answer some questions -- Is the cosmos eternal? Does a Tathagataexist after death? -- he would give up being a monk. The Buddha replied that Malunkyaputta was like a man struck by a poisoned arrow, who would not have the arrow removed until someone told him the name of the man who had shot him, and whether he was tall or short, and where he lived, and what sort of feathers were used for the fletchings.

the Buddha said. "Because they are not connected with the goal, are not fundamental to the holy life. They do not lead to disenchantment, dispassion, cessation, calming, direct knowledge, self-awakening, Unbinding."

However, Later the Buddha followers improved metaphysics question compare with scientific that

Modern science says that some millions of years ago, the newly cooled earth was lifeless and that life originated in the ocean. Buddhism never claimed that the world, sun, moon, stars, wind, water, days and nights were created by a powerful god or by a Buddha. Buddhists believe that the world was not created once upon a time, but that the world has been created millions of times every second and will continue to do so by itself and will break away by itself. According to Buddhism, world systems always appear and disappear in the universe.
