According to Matsyapurāṇa (Matsyapurana), this tīrtha is situated on the bank of the river Narmadā (Narmada). It is said that Ahalyā (Ahalya) attained salvation, by performing tapasyā (tapasya; ascetic penance) in this place —
ahalyā ca tapastatvā tatra muktimupāgatā.

Again, according to Brahmapurāṇa (Brahmapurana), this tīrtha was located by Godāvarī (Godavari)or Gautamī Gaṅgā (Gautami Ganga). From the description of Śivapurāṇa (Jñāna/54 adhyāya), it becomes evident that Godāvarī is called Gautamī Gaṅgā. According to scholars, the northern portion of Godāvarī is called Gautamī Gaṅgā.

When Indra violated Ahalyā’s chastity, her husband Maharṣi Gautama asked her to become a river and get assimilated with Gautamī Gaṅgā, and again come back to her own self after that. The place where Ahalyā, as a river, got merged with Gautamī, is called Ahalyātīrtha (Ahalyatirtha) or Ahalyāsaṅgamatīrtha (Ahalyasangamatirtha). Gautama also asked Indra to take a bath in this river, to get rid of his sins. So it is also called Indratīrtha (Indratirtha).

There is a temple of Ahalyeśvara in the modern Bhalod region, which may be identical with this site.
