The third reason the Buddha did not believe in a god is that the belief is not necessary. Some claim that the belief in a god is necessary in order to explain the origin on the universe. But this is not so. Science has very convincingly explained how the universe came into being without having to introduce the god-idea. Some claim that belief in god is necessary to have a happy, meaningful life. Again we can see that this is not so. There are millions of atheists and free-thinkers, not to mention many Buddhists, who live useful, happy and meaningful lives without belief in a god. Some claim that belief in god’s power is necessary because humans, being weak, do not have the strength to help themselves. Once again, the evidence indicates the opposite. One often hears of people who have overcome great disabilities and handicaps, enormous odds and difficulties, through their own inner resources, through their own efforts and without belief in a god. Some claim that god is necessary in order to give man salvation. But this argument only holds good if you accept the theological concept of salvation and Buddhists do not accept such a concept. Based on his own experience, the Buddha saw that each human being had the capacity to purify the mind, develop infinite love and compassion and perfect understanding. He shifted attention from the heavens to the heart and encouraged us to find solutions to our problems through self-understanding.
