Frequently asked questions

What is a yantra?
A geometric diagram used as a meditation and worship support — the visual counterpart of a mantra. Planetary yantras encode a graha’s energy, often as a magic-square grid whose rows sum to the planet’s number.

Where should I place a yantra?
Traditional placement: face the yantra in the recommended direction for its planet (e.g., the Sun's yantra facing East), place it at eye level or slightly below on a clean surface, and ideally in the puja or meditation area of the home — never on the floor, in the bedroom (for most yantras), or in a cluttered space. Energize it before placement and offer incense or water regularly as part of worship.
How is a yantra energised (pran pratishtha)?
Traditionally, a yantra is purified, then consecrated with the planet's mantra and installed facing the recommended direction, often on an auspicious day for that planet. The calculator recommends the yantra based on your Moon-sign lord and provides the classical energisation steps, including cleansing, mantra chanting, and placement. Consecration is considered essential — an unconsecrated yantra is treated as decorative.
Is the Shree Yantra better than a planetary yantra?
They serve differently: the Shree Yantra is the universal abundance diagram suitable for everyone; a planetary yantra targets one graha’s themes. Many keep the Shree Yantra centrally and add their personal planet’s yantra.
