Matsya Purana — Procedure for Going to Prayaga and the Greatness of the Ganga
सर्वेषामेव भूतानां पापोपहतचेतसाम् गतिम् अन्विष्यमाणानां नास्ति गङ्गासमा गतिः //
sarveṣāmeva bhūtānāṃ pāpopahatacetasām gatim anviṣyamāṇānāṃ nāsti gaṅgāsamā gatiḥ //
For all beings whose minds have been struck down by sin and who seek a saving course, there is no path of deliverance equal to the Gaṅgā.
This verse does not discuss cosmic creation or Pralaya; it teaches a soteriological principle: the Ganga is the foremost means of purification and refuge for sin-afflicted beings.
It supports Dharma-based conduct by emphasizing prayāścitta (atonement) and purification: a householder or king should uphold sacred observances, sponsor pilgrimage and bathing rites, and guide society toward ethical reform through recognized purifying disciplines centered on the Ganga.
The ritual takeaway is primary: the Ganga is upheld as the supreme purifier—implying high merit for Ganga-snāna (sacred bathing), tirtha-yātrā (pilgrimage), and related rites performed on her banks.
