Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
सम्भेदश् चण्डवेगायास् तथैवामरकण्टकम् कुरुक्षेत्राच्छतगुणं तस्मिन्स्नानादिकं भवेत् //
sambhedaś caṇḍavegāyās tathaivāmarakaṇṭakam kurukṣetrācchataguṇaṃ tasminsnānādikaṃ bhavet //
The sacred confluence (saṃbheda) of the Caṇḍavegā, and likewise Amarakaṇṭaka, are said to yield merit a hundred times greater than Kurukṣetra; therefore bathing and other rites performed there become supremely fruitful.
This verse does not address pralaya; it focuses on tirtha-mahātmya—how specific sacred places amplify the merit of rites like bathing.
It supports the householder/kingly duty of dharma through pilgrimage and ritual observance: performing snāna and allied rites at eminent tirthas is presented as a powerful means of accruing merit and sustaining religious order.
The ritual point is primary: snāna (sacred bathing) and accompanying practices at the Caṇḍavegā confluence and at Amarakaṇṭaka are declared exceptionally efficacious—hundredfold compared to Kurukṣetra.
