Matsya Purana — Procedure for Going to Prayaga and the Greatness of the Ganga
गङ्गामेव निषेवेत प्रयागं तु विशेषतः नान्यत्कलियुगे घोरे भेषजं नृप विद्यते //
gaṅgāmeva niṣeveta prayāgaṃ tu viśeṣataḥ nānyatkaliyuge ghore bheṣajaṃ nṛpa vidyate //
One should resort to the Gaṅgā alone—above all, to Prayāga in particular; for in the dreadful Kali Age, O King, no other remedy is found.
This verse does not discuss Pralaya; it teaches a Kali-yuga upāya (remedial practice), declaring pilgrimage and resort to the Ganga—especially Prayaga—as the foremost spiritual “medicine.”
By addressing “O King,” it frames royal/householder dharma as ensuring access to purifying tirthas and personally practicing humility and expiation—seeking inner purification through Ganga/Prayaga rather than relying only on complex rites in Kali-yuga.
Ritually, it prioritizes tirtha-sevā—especially bathing, worship, and observance at Prayaga (the confluence)—as a principal Kali-yuga practice; it does not prescribe Vastu/temple construction rules in this specific line.
