Matsya Purana — Śrāddha Procedure: Types
ब्रह्मण्यो योगविच्छान्तो विजितात्मा च शीलवान् भोजयेच्चापि दौहित्रं यत्नतः स्वसुहृद्गुरून् //
brahmaṇyo yogavicchānto vijitātmā ca śīlavān bhojayeccāpi dauhitraṃ yatnataḥ svasuhṛdgurūn //
Celui qui est dévoué aux brahmanes et à Brahman (l’ordre sacré), paisible par la discipline du yoga, maître de soi et de bonne conduite, doit aussi, avec le soin requis, offrir un repas—en particulier au fils de sa fille—et nourrir avec diligence ses amis et ses maîtres (gurus).
This verse does not discuss Pralaya; it focuses on Dharma—self-mastery and the merit of feeding worthy recipients such as gurus, friends, and family.
It reinforces gṛhastha (householder) ethics: cultivate self-control and virtuous conduct, and perform annadāna by feeding respected elders/teachers, well-wishers, and close kin—acts considered socially stabilizing and religiously meritorious.
No Vāstu or temple-architecture rule is stated; the ritual takeaway is the importance of bhojana/annadāna (hosting and feeding) as a prescribed act of righteousness.
