Yantra is a mystical diagram used in the Indian religions and philosophy for worship. It is used to help in meditation and for the benefits of its purported occult powers based on Tantric texts and Hindu astrology. It is a type of mandala, which is a spiritual symbol representing the universe.
In classical Sanskrit, the word, yantra, means âinstrument,â âapparatusâ or âcontrivance.â It is derived from the root word, yam, meaning “to support” or “to sustain the essence of an object/concept.”
