Hinduism is believed to be one of the oldest living religions on Earth, with origins tracing back to the ancient Vedic civilization in India. The earliest Hindu spiritual text, the Rig Veda, was compiled in approximately 900 B.C. Other sacred Hindu scriptures include the Upanishads, the Bhagavad Gita, and Ramayana among others. With its deep spiritual roots, Hinduism is a vastly diverse and colorful religion. Hindus believe in reincarnation, the law of cause and effect (karma), a single Divine Being with multiple manifestations, and the desire of all beings for liberation from the cycle of birth and death.
