The oldest religion in the world, Hinduism originated in the Indus River Valley about 4,500 years ago in what is now modern-day northwest India and Pakistan. It arose contemporaneously with ancient Egyptian and Mesopotamian cultures. With roughly one billion followers, Hinduism is the third-largest of the world’s religions. Hindus believe in a divine power that can manifest as different entities. Three main incarnations—Brahma, Vishnu, and Shiva—are sometimes compared to the manifestations of the divine in the Christian Trinity.

Multiple sacred texts, collectively called the Vedas, contain hymns and rituals from ancient India and are mostly written in Sanskrit. Hindus generally believe in a set of principles called dharma, which refer to one’s duty in the world that corresponds with “right” actions. Hindus also believe in karma, or the notion that spiritual ramifications of one’s actions are balanced cyclically in this life or a future life (reincarnation).
