Trinity - Brahma, Vishnu, Shiva
In the Hindu religion, there is an uncountable number of gods, some say there is one for almost every village in India. The three most recognized gods, the trinity, Vishnu Brahma and Shiva are all present in the story of creation. Vishnu was awoken and from his navel grew a lotus, and Brahma arose from the lotus and broke the lotus into three parts, heaven, earth, and the skies. Shiva often does not appear in the story, but in some versions he appears dancing when the world is in chaos.
