Narmadā-māhātmya: Amarakāṇṭaka, Jāleśvara, Kapilā–Viśalyakaraṇī, and the Supreme Purifying Power of Darśana
नर्मदा सर्वतः पुण्या ब्रह्महत्यापहारिणी / अहोरात्रोपवासेन मुच्यते ब्रह्महत्यया
narmadā sarvataḥ puṇyā brahmahatyāpahāriṇī / ahorātropavāsena mucyate brahmahatyayā
The Narmadā is holy in every way and removes the sin of brahmin-slaying. By fasting for a full day and night, one is released from the guilt of brahmin-slaying.
Lord Kūrma (Vishnu) instructing sages (tirtha-mahātmya context)
Primary Rasa: shanta
Secondary Rasa: karuna
Indirectly: it emphasizes purification (śuddhi) through tirtha and vrata as a dharmic support for inner clarity, which prepares the seeker for knowledge of the Self taught elsewhere in the Kurma Purana.
Ahorātra-upavāsa (fasting for a full day and night) is presented as a disciplined observance (vrata/tapas) that supports restraint, purification, and readiness for higher sādhanā such as mantra, japa, and contemplative practice.
By focusing on dharma, tirtha, and purification rather than sectarian identity, it reflects the Kurma Purana’s integrative stance where Vishnu (as Kūrma) teaches practices also valued in Shaiva traditions of tapas and expiation.
