Devatā-Pratiṣṭhā: Maṇḍapa Construction, Dikpāla Worship, Kalaśa-Abhiṣeka, Nyāsa and Homa Procedures
मन्त्रन्यासं गुरुः कृत्वा ततः कर्म समारभेत् / प्रासादस्याग्रतः कुर्यान्मण्डपं दशहस्तकम्
mantranyāsaṃ guruḥ kṛtvā tataḥ karma samārabhet / prāsādasyāgrataḥ kuryānmaṇḍapaṃ daśahastakam
After the guru has performed mantra-nyāsa (the placing of mantras), he should then begin the ritual work. Before the temple shrine, he should construct a maṇḍapa measuring ten hastas.
Lord Vishnu (in instruction to Garuda)
Concept: Ritual efficacy requires prior consecration of the body/space through mantra-nyāsa, then orderly commencement of karmas in a properly prepared venue.
Vedantic Theme: Mantra as a vehicle for focusing consciousness; disciplined action (karma) performed with sanctified intention supports purification and devotion.
Application: Begin any major rite with preparatory sanctification (nyāsa/ācamanā/saṅkalpa); ensure the physical setting is prepared to specification before proceeding.
Primary Rasa: shanta
Type: temple precinct
Related Themes: Garuda Purana 1.48 (mandapa/vedi measurements and preparations)
This verse places mantra-nyāsa as the prerequisite that sanctifies the officiant and the rite, after which the main ritual work is properly begun.
It instructs that a maṇḍapa (pavilion) should be made in front of the temple shrine, with a specified standard measure of ten hastas.
Begin any sacred undertaking with proper preparation and consecration under qualified guidance, and follow clear standards (measurements/procedure) rather than improvising.
