Matsya Purana — The Greatness of Prayāga
तेन दानेन दत्तेन योगं नाभ्येति मानवः प्रयागे तु मृतस्येदं सर्वं भवति नान्यथा //
tena dānena dattena yogaṃ nābhyeti mānavaḥ prayāge tu mṛtasyedaṃ sarvaṃ bhavati nānyathā //
By that act of charity—though duly given—a person does not attain the supreme spiritual union (yoga). But for one who dies at Prayāga, all this (highest merit and spiritual attainment) indeed comes to pass—there is no other outcome.
This verse is not about Pralaya; it focuses on tirtha-mahātmya—stating that Prayāga uniquely grants the highest spiritual result at death, beyond what ordinary charity alone yields.
It differentiates ordinary meritorious duty (dāna/charity, a key householder and royal obligation) from direct liberative attainment, emphasizing that pilgrimage and sacred-place observances are also recognized means toward the highest goal in the Matsya Purana’s ethics.
No Vāstu or iconography rule is stated here; the ritual takeaway is the exceptional salvific status of Prayāga as a tirtha, implying heightened efficacy of rites and final rites performed there.
