Concept Of Yantra
The Sanskrit word 'Yantra' derives from the root 'yam' meaning to sustain, hold or support the energy inherent in a particular element, object or concept. It is usually composed of an outer geometrical form enclosing interior geometrical designs. Each particular design is used for a specific purpose or intent. In its first meaning, 'Yantra' may refer to any kind of mechanical contrivance, which is harnessed to aid an enterprise. A Yantra in this sense, therefore, is any sort of machine or instrument such as is used in architecture, astronomy, alchemy, chemistry, warfare or recreation.
In Indian culture from Ancient times to achieve happiness, prosperity, long life and good health; there has been quite an important role of Yantra, Tantra and Mantra. These Mystical Diagrams called Yantra are written on Tantra in the form of Gold, Silver, copper, Asthdhatu and Bhoj Patra symbolize different Powers. These Yantra are energized or Pran Pratishthit by using different Mantras of respective Deities. These deities in Yantra then help in achieving Particular task or desire. Yantra are energized by Seed and Tantrik Mantra which give immediate results and help in achieving desired results.
A Yantra is a geometric design acting as a highly efficient tool for contemplation, concentration and meditation. Yantras carry spiritual significance, and point the user to higher levels of consciousness.
The Yantra provides a focal point that is a window into the absolute. When the mind is concentrated on a single, simple object (in this case a Yantra), the mental chatter ceases. Eventually, the object is dropped when the mind can remain empty and silent without help. In the most advanced phases, it is possible to attain union with God by the geometric visualization of a Yantra.
A Sanskrit text of the eleventh century AD, Samarangana Sutradhara on the science of architecture, gives vivid descriptions of the making and operating of such mechanical Yantra as a wooden flying bird, wooden aero planes meant to fly with hot mercury as fuel, male and female robot figures, etc. The meaning of the term Yantra has been expanded to refer to religious enterprises, and has acquired a special theological significance. Mystic Yantra are aids to and the chief instruments of meditative discipline. Basically a Yantra used in this context and for this purpose is an abstract geometrical design intended as a 'tool' for meditation and increased awareness.
