Yantras are geometrical figures intended to represent the basic energies. Just as every elementary geometrical figure, a straight line, a square, a cross or a triangle etc., has a symbolic value corresponding to the basic notions, similarly, the Yantras symbolise one or the other power or energy. In other words Vedic Yantras are the graphic representations of Mantras. Yantras can be drawn, engraved or painted on a variety of substances. The classical eight tantrik surfaces are gold, silver, copper, crystal, birch, bone, hide (which can include any type of paper), and Vishnu stone (shalagrama).
The Vedic Yantras are designed to remove the afflictions to obtain a specific result. The Yantras are inscribed with the mystical inscriptions of the afflicted beneficial planets at a particularly auspicious time to suit the individual wearer. The yantras shall be seen daily in the morning and one shall lit incense or lamp before the yantra every morning. It is auspicious and blesses the native with success and wealth by continous puja of Yantras.
