Yantras are usually used for counteracting the harmful effects of planets. Besides countering negative effects, Yantras also increase the planets' beneficial aspects in our lives. Yantras and mantras are connected together since each Yantra has a corresponding mantra. The yantras are also representative of different deities. According to Ayurveda, there is also a definite relationship between Vedic talisman and the elements of Earth, Water, Fire, Air and Ether.
