The word Yantra is driven from Sanskrit that means an instrument or machine. However this Yantra does not has mechanical parts which together form a machine complete. This Yantra is in fact a spiritual machine. It is an amazing device that interacts with nature, divine powers, heavenly bodies, and their respective Gods. It is a holy miracle of ancient Indian Science that is largely based on Vedas and Purans.

A Yantra itself cannot be effective without use of relevant Tantra and Mantra. As mentioned in Vedas, a Yantra becomes powerful and active only when related Mantra is hymned with proper Tantra Practice. When all three are mannered in the guided way, they create an auspicious sound wav or vibration.

When a Mantra is hymned through appropriate Tantra, the practice turns on the power of a Yantra. This power remains in the form of vibration or wav that reaches to concerned God or Goddess. After that, this energy agreed and retransmitted by the deity. When this divine energy comes in contact with Sadhak (the practitioner), then it creates an aura around him / her.  

In this way, the aim of worshiping a yantra is realised here and the worshiper is sanctified with blessings for which he or she began the whole practice.
