Matsya Purana — The Rite and Glory of Meru-Dāna: The Tenfold ‘Gift of Meru’ and Mountain-Offe...
स्नात्वाथ गुरवे दद्यान् मध्यमं पर्वतोत्तमम् विष्कम्भपर्वतान्दद्याद् ऋत्विग्भ्यः क्रमशो मुने //
snātvātha gurave dadyān madhyamaṃ parvatottamam viṣkambhaparvatāndadyād ṛtvigbhyaḥ kramaśo mune //
After bathing, one should present to the guru the “middle” portion of the excellent Parvata-offering; and then, O sage, one should give the Viṣkambha-parvatas to the officiating priests (ṛtvij) in due order.
This verse is not about pralaya; it focuses on ritual propriety—bathing and then distributing prescribed gifts (parvata-type offerings) to the guru and the officiating priests in a defined order.
It reflects the dharmic duty of a yajamāna (householder/king performing rites) to honor the guru and compensate ṛtviks with appropriate dakṣiṇā, emphasizing purity (snāna), hierarchy (guru first), and orderly distribution (kramaśaḥ).
The key ritual detail is ‘parvata’ offerings—mountain-shaped models/heaps given as dāna—assigned by grade (“madhyama”) and type (“viṣkambha”), and distributed to guru and priests according to sequence, aligning with formal śrauta/smārta gift-protocols.
