In the traditional biography of the Buddha (Siddhartha Gautama), he preached his first sermon:

to five of his former associates with whom he had once practiced asceticism.

Explanation:

Siddhartha had recognized that human misery is closely bound up with the essence of life, the reality of being born, and that it was important to transcend ignorance and tamper with impulses and desires in order to avoid the cycle of reincarnations. The charity has been a way to desire the salvation of all men. After years of asceticism and meditation, he decided to preach his companion who became his first disciples in Sarnath. They preached the new truth throughout India.
