What are the types of yantras?
There are four basic types of Yantras: Yantras of deities, of which the most prominent are the Shakta Yantras (these are usually forms of the Great Mother or the Mahavidyas- ‘Sources of supreme knowledge’); Astrological Yantras (used to harness the energies of the nine major planets); Architectural Yantras (used for the ground plans of temples); and, the Numerical Yantras (comprising select combinations of numbers which serve as talismans). Yantras, besides fulfilling their basic purpose, can help you prosper in your business or career and also help bestow good health, wealth, happiness and success upon you. These Yantras, be it copper/panch-dhatu/crystal, can be placed in your temple, put above a door or kept at your work place where, if worshipped with sincere devotion, they will bring their own rewards.
