Yantra (यन्त्र) (Sanskrit) (literally "machine, contraption" is a mystical diagram, mainly from the Tantric traditions of the Indian religions. They are used for the worship of deities in temples or at home; as an aid in meditation; used for the benefits given by their supposed occult powers based on Hindu astrology and tantric texts. They are also used for adornment of temple floors, due mainly to their aesthetic and symmetric qualities. Specific yantras are traditionally associated with specific deities.
Representations of the yantra in India have been considered to date back to 11,000-10,000 years BC. The triangular-shaped stone, which includes triangular engravings on one side, was found daubed in ochre, in what was considered a site related to worship. Worship of goddesses in that region was found to be practiced in a similar manner to the present day
In Rigvedic Sanskrit, it meant an instrument for restraining or fastening, a prop, support or barrier, etymologically from the root yam "to sustain, support" and the -tra suffix expressing instruments.:
Mantras, the Sanskrit syllables inscribed on yantras, are essentially "thought forms" representing divinities or cosmic powers, which exert their influence by means of sound-vibrations.
Yantras are usually associated with a particular deity and are used for specific benefits, such as: for meditation; protection from harmful influences; development of particular powers; attraction of wealth or success, etc. They are often used in daily ritual worship at home or in temples, and sometimes worn as a talisman.
As an aid to meditation, yantras represent the deity that is the object of meditation. These yantras emanate from the central point, the bindu. The yantra typically has several geometric shapes radiating concentrically from the center, including triangles, circles, hexagons, octagons, and symbolic lotus petals. The outside often includes a square representing the four cardinal directions, with doors to each of them. A popular form is the Sri Chakra, or Sri Yantra, which represents the goddess in her form as Tripura Sundari. Sri Chakra also includes a representation of Shiva, and is designed to show the totality of creation and existence, along with the user's own unity with the cosmos.
We at Kallur Mana, all the Yantras are drawn and prepared by hand only. Yantras are made individually after checking horoscopes and current planetary positions, from a huge collection of more than 400 yantras for different purposes.
