Matsya Purana — Rite and Merits of the Sesame-Mountain
इत्यामन्त्र्य च यो दद्यात् तिलाचलमनुत्तमम् स वैष्णवं पदं याति पुनरावृत्तिदुर्लभम् //
ityāmantrya ca yo dadyāt tilācalamanuttamam sa vaiṣṇavaṃ padaṃ yāti punarāvṛttidurlabham //
Thus, having duly invoked and taken leave, whoever gives the unsurpassed ‘Tilācala’—the ceremonial mound or mountain of sesame as a gift—attains the Vaiṣṇava abode, from which return to rebirth is rarely possible.
This verse does not address pralaya directly; it focuses on dāna (charitable ritual giving) as a means to attain the Vaiṣṇava abode and minimize return to saṃsāra.
It frames a householder/kingly duty as dāna performed with proper ritual etiquette (āmantraṇa), promising spiritual merit culminating in a Vaiṣṇava goal rather than merely worldly reward.
The ritual focus is Tilācala—constructing/arranging a symbolic ‘mountain’ of sesame for donation—highlighting prescribed ceremonial forms (invocation/leave-taking) rather than temple architecture.
