The principal teachings of Gautama Buddha can be summarised in what the Buddhists call the 'Four Noble Truths':
First - There is suffering and misery in life.
Second- The cause of this suffering and misery is desire.
Third - Suffering and misery can be removed by removing desire.
Fourth - Desire can be removed by following the Eight Fold Path.
ABSENCE OF THE CONCEPT OF GOD IN BUDDHISM
Buddha was silent about the existence or non-existence of God. Buddhism provided Dhamma or the 'impersonal law' in place of God. Many scholars consider the evolution of the concept of Buddha as a god or as an object of worship within Buddhism as an effect of Hinduism.
BUDDHAS ARE ONLY PREACHERS:
According to the Dhammapada, Sacred Books of East volume 10 pg., 67: "The Jathagatas (Buddhas) are only Preachers."
This confirms the age-old tendency amongst humans to deify and worship those human beings who have been preachers and reformers. Gautam Buddha never claimed to be God nor did he ask or instruct that he should be worshipped in any way or form.
