Matsya Purana — Agastya’s Origin
सकांस्यपात्राक्षतशुक्तियुक्तं मन्त्रेण दद्याद्द्विजपुंगवाय उत्क्षिप्य लम्बोदरदीर्घबाहुम् अनन्यचेता यमदिङ्मुखः सन् //
sakāṃsyapātrākṣataśuktiyuktaṃ mantreṇa dadyāddvijapuṃgavāya utkṣipya lambodaradīrghabāhum ananyacetā yamadiṅmukhaḥ san //
With a mantra, one should present to an excellent brāhmaṇa a bronze vessel furnished with unbroken grains of rice and a conch-shell; lifting up in reverence the one with a pendulous belly and long arms, he should do so with undistracted mind, facing the direction of Yama (the south).
This verse is not about pralaya; it gives a ritual instruction (dāna-vidhi), emphasizing mantra-recitation, focused attention, and the rule of facing Yama’s direction (south) during the act.
It frames dharmic duty as disciplined giving: a householder (or ruler as patron) should donate properly prepared items to a worthy brāhmaṇa, with mantra and mental concentration, following prescribed ritual orientation.
Ritually, it specifies the offering set (bronze vessel + akṣata + conch) and a directional injunction—performing the act facing south (Yama-diśā)—highlighting procedural precision rather than Vāstu/temple architecture.
