Buddhism is merely the philosophy of the way of life!
The term Buddha literally means enlightened one, a knower.
All the teachings of the Buddha can be summed up in one word: Dhamma. It means truth, that which really is. It also means law, the law which exists in a man's own heart and mind. It is the principle of righteousness. Therefore the Buddha appeals to man to be noble, pure, and charitable not in order to please any Supreme Deity, but in order to be true to the highest in himself.
