Yantra literally means "Loom, "Instrument or Machine". In actual practice, a Yantra is a symbolic representation of aspects of divinity, usually the Mother Goddess. Yantra is a diagrammatic representation of Mantras. It is an interlocking matrix of geometric figures, circles, triangles and floral patterns that form fractal patterns of elegance and beauty. Although the Yantra is primarily a meditation tool both for serious spiritual seekers as well as sculptors in the classical tradition, its Shakti is also available to new seekers.

Rudra Centre's Yantras are sanctified and energized through an elaborate ritual by specialized priests at a temple in Maharashtra, India. The Pranapratistha ritual is performed to infuse the Yantras with "life force" or energies of respective deities. Rudra Centre's energized Yantras can be placed in the temple, above a door or kept at the place of work where, if worshipped with sincere devotion, rewards will unfold. It is important for a Yantra to be energized as it has to be brought "to live" through the specifically prescribed ritual so that it can radiate its beneficence optimally. An un-energized Yantra can be compared to a very complex music system that has been plugged in but not tuned or turned on and the aspirant has no idea which button will activate it

Since time immemorial, it is believed that mystical Yantras reveal inner basis of forms and shapes abounding in the universe. Yantras function as revelatory symbols of cosmic truths.

How soon can one expect to experience the benefits of wearing or installing a Yantra?. Yantras usually takes 45 days but this is a conservative estimate. Some Yantras activate results almost immediately if one's karmic potential is ripe. Others work better over the long term, gradually but steadfastly increasing stages of blessings. Yantras for prosperity and wealth are usually of this category. Hence patience is required. For example, the Lord Kuber Yantra may or may not bestow immediate results but the patient person will eventually see benefits.

For those who prefer simple worship of a Yantra, traditionally a small lighted oil-lamp or ghee lamp placed in front of the Yantra is regarded as the best form of simple worship. The lighting of incense of various types is also well regarded as is the auditory stimuli of chanting Mantras or playing tapes of sacred chants. As Yantras are living energy systems, they respond to all sensory stimuli. Perfume is perceived as a vain affectation and is to be avoided especially as most perfumes consist of synthetic components.
