Summary of chapter 185 of the Agni Purāṇa is as follows:
Vratas on the ninth tithi, principally associated with Durgā, are described. The Gaurī-navamī on Āśvayuja-śukla-navamī and the Piṣṭaka-navamī involving flour-food offerings are noted. The Mahānavamī occurs when the Mūla-nakṣatra coincides with the ninth tithi while the Sun is in Virgo; on this occasion nine forms of Durgā are installed at the eight directions and centre, with the principal image being the aṣṭādaśabhuja Mahiṣamardinī. The ten-syllable Durgā-mantra "Oṃ durge durga-rakṣaṇi svāhā" is given as the japa-text. Nine Caṇḍā-forms—Rudracaṇḍā, Pracaṇḍā, Caṇḍogrā, and others—receive bali of khaḍga, blood, and flesh, and the four directional śaktis—Jayantī, Maṅgalā, Kālī, Bhadrakālī—are propitiated.
