Matsya Purana — Procedure for Going to Prayaga and the Greatness of the Ganga
सर्वत्र सुलभा गङ्गा त्रिषु स्थानेषु दुर्लभा गङ्गाद्वारे प्रयागे च गङ्गासागरसंगमे तत्र स्नात्वा दिवं यान्ति ये मृतास्ते ऽपुनर्भवाः //
sarvatra sulabhā gaṅgā triṣu sthāneṣu durlabhā gaṅgādvāre prayāge ca gaṅgāsāgarasaṃgame tatra snātvā divaṃ yānti ye mṛtāste 'punarbhavāḥ //
The Gaṅgā is easy to access in many places, yet she is truly rare in three sites in her highest potency: at Gaṅgādvāra, at Prayāga, and at the confluence where the Gaṅgā meets the ocean. Those who bathe there and then die attain heaven; they do not return again to rebirth.
It does not describe Pralaya directly; it presents a salvation-oriented tirtha teaching, emphasizing that certain sacred confluences of the Gaṅgā confer exceptional spiritual results beyond ordinary places.
It supports the householder/kingly duty of supporting dharma through pilgrimage, sacred bathing, and patronage of tirthas—promoting purity, merit, and liberation-oriented practice within worldly life.
Ritually, it highlights snāna (sacred bathing) at three premier tirthas—Gaṅgādvāra, Prayāga, and Gaṅgāsāgara—implying these sites are prime locations for ghāṭa use, vows, and pilgrimage observances.
