Buddhism is the law of nature. What the Buddha perceived and taught is the law of nature.
The Buddha taught many things, but the basic concepts in Buddhism can be summed up by the Four Noble Truths and the Noble Eightfold Path.
Buddhism teaches that the solutions to our problems are within ourselves not outside.
Buddhism explains a purpose to life, it explains apparent injustice and inequality around the world, and it provides a code of practice or way of life that leads to true happiness.
