Yantra is an instrument, or a talisman or a mystical diagram usually in copper. It is a technique or path, considered the simplest and shortest, through which one can attain one’s desires, and fulfil one’s wishes. It is said that the ‘Deities’ reside in the Yantras. More
Mantras evolved by Rishis and Yogis who actually prepared them and used them to prove their worth. Over the ages these have helped thousands of Sadhaks achieve even that which appeared impossible to them. Mantra, hence, is an undoubted means of fulfilling one’s wishes.
