Mantra Hindu is a type of spiritual practice in Hinduism, which involves the repetition of a sacred phrase or sound. The term 'Mantra Hindu' is derived from two Sanskrit words: 'MAN, ' meaning 'MIND, ' and 'tra, ' meaning 'INSTRUMENT.' OM is a sacred sound and a spiritual symbol in Hinduism, Buddhism, Jainism, and Sikhism. It is believed to be the primordial sound of the universe and is used as a mantra in meditation.
