The Vastu Purusha Devata Dhyana Mantra is a meditative invocation of Vastu Purusha, the cosmic being who embodies the site and structure of a dwelling. According to the Vastu Shastra texts, such as the Mayamata and the Manasara, Vastu Purusha is the presiding deity of the plot, lying face-down with his head in the northeast and feet in the southwest, covering the entire site. The dhyana mantra is used to visualize his form and seek his blessings for harmony and prosperity. The mantra typically begins with 'Om' and includes descriptive epithets of the deity. The beej-akshara 'Vam' (वं) is often associated with Vastu Purusha, representing the element of water and the stabilizing energy of the site.
Phonetically, the mantra's syllables are designed to resonate with the spatial energies of the building. The traditional purpose of this mantra is to align the structure with the cosmic order, removing obstacles and ensuring the well-being of the inhabitants. It is chanted during Griha Pravesh (housewarming) and Vastu Puja ceremonies, as prescribed in the Agamas. The recommended chanting count is 108 times, preferably in the morning or during the auspicious time of the Vastu ritual. The practitioner should face the northeast direction, which is the head of Vastu Purusha.
Cautions include avoiding chanting during eclipses or inauspicious periods, and maintaining purity of body and mind. The mantra is also used in daily meditation to cultivate a harmonious living space. According to the Shaktisangama Tantra, Vastu Purusha is a form of Bhumi Devi, the earth goddess, and the dhyana mantra invokes her protective aspect. The Lalita Sahasranama also references the cosmic being as the support of all structures. The mantra's benefits include stability of the building, peace in the family, and protection from negative energies.
It is considered a foundational practice in Vastu Shastra for creating a balanced environment.
