Hinduism is the oldest religion in the world, and it is still practiced by over a billion people today. Hinduism is a polytheistic religion, which means that it has many gods and goddesses. The most important Hindu gods are Brahma, Vishnu, and Shiva. Brahma is the creator of the universe, Vishnu is the preserver of the universe, and Shiva is the destroyer of the universe.

Buddhism is a religion that was founded by Siddhartha Gautama, who is also known as the Buddha. The Buddha lived in India in the 6th century BCE. He taught that the cause of suffering is desire, and that the way to end suffering is to extinguish desire. Buddhism is a non-theistic religion, which means that it does not believe in a personal god.

Mahavira taught that the way to achieve liberation from suffering is to follow the path of non-violence, non-attachment, and self-control.
