Term: yantra

DEFINITIONs:
1.  From the ancient Sanskrit, it literally means “machine,” specifically a machine or instrument that restrains. In use, yantras are generally diagrams that Tantrics use in specific ways to restrain unwanted aspects of their own minds. In India, the best known yantra is the Sri Yantra. The term may also refer to amulets, hand postures, and even devices used in alchemy. In some traditions, yantras are used to control evil entities or the physical world.

2.  Sanskrit term meaning "Conception instrument." A geometric-style of diagram from Tantric philosophy used for concentration and in ritual to represent and contain specific psychic energies. Meditation on the Yantra will induce specific consciousness experiences.

The prefix yan- means "to conceive, perceive, imagine, visualize," and the suffix -tra equals an "instrument, implement or tool." Hence, a yantra is a tool for focusing the mind and encouraging clarity of conception.
