Yantra is the Sanskrit word which means an instrument or a machine. In Tantric texts and Bhramanical Texts it means Visual Mantras or in easy words mantras made in geometrical figures and colours to influence the environment, cosmic forces, spirits around us, the evil eye of our enemies and our own aura and mental makeup. In Hindu and Buddhist mysticism this kind of geometric forms known as Yantra in Hindus and Thangka Paintings or simply Thangka in Buddhist areas is widely seen in Temples, monasteries, Homes and Viharas.
