The Yantra Puja Mantra is a class of mantras used to invoke the power of sacred yantras, most notably the Sri Yantra (Sri Chakra). These mantras are central to the Sri Vidya tradition, which is extensively detailed in texts such as the *Lalita Sahasranama* and the *Yogini Hridaya*. The Sri Yantra itself is a geometric diagram composed of nine interlocking triangles surrounding a central bindu, representing the union of Shiva and Shakti. The primary deity associated is Tripura Sundari, the supreme goddess of the Sri Vidya tradition, though the mantras may also be directed to the ten Mahavidyas.
The beej-akshara (seed syllable) often employed is 'Shreem' (श्रीं), which is the bija of Lakshmi and abundance, but in the Sri Yantra context it is linked to Tripura Sundari's grace. Phonetically, 'Shreem' combines the sibilant 'sh' with the resonant 'r' and the nasal 'm', creating a vibration that aligns with the yantra's geometry. According to the *Mantra Mahodadhi*, the purpose of yantra puja is to establish a direct connection with the cosmic geometry of the divine, enabling the practitioner to manifest desires and achieve spiritual progress. The mantras are chanted during the ritual of nyasa (placement of mantras on the body) and avahana (invocation) of the deity into the yantra.
Traditional benefits include desire fulfillment, protection, and attainment of siddhis (supernatural powers). The recommended chanting context is during specific lunar phases, particularly the full moon or during Navaratri, with a minimum of 108 repetitions using a rudraksha or sphatika mala. The ritual setting should be a clean, sanctified space with the yantra placed on a copper or silver plate. Cautions include the necessity of initiation (diksha) from a qualified guru for the higher mantras, as improper chanting may lead to adverse effects.
The *Devi Mahatmya* emphasizes the importance of correct pronunciation and mental focus. The Yantra Puja Mantra thus serves as a powerful tool for aligning the microcosm of the practitioner with the macrocosm of the divine, as described in the *Sri Yantra texts*.
Om, salutations to Tripura Sundari, with the seed syllables Shreem, Hreem, Kleem, Aim, Sauh.
The mantra contains five seed syllables: śrīṃ (abundance), hrīṃ (transformation), klīṃ (attraction), aiṃ (knowledge), sauḥ (solar energy). These bijas correspond to the five elements and the five faces of Shiva, aligning the practitioner with the cosmic geometry of the Sri Yantra.
