This is a special fast taken in the month of तुलाम् (October-November) with a view to obtain 'Bhukti' (enjoyment or possession) and 'Mukti' (Beatitude). The important rite of this worship is to take fast on the ninth night of the bright lunar fortnight in the month of तुलाम् and worship goddess गौरी . This नवमी is also called गौरीनवमी . Another name of this नवमी is पिष्टाकनवमी . This name is given because on that day पिष्टम् (ground rice) is eaten and the goddess is worshipped. In the bright lunar fortnight of the month of तुलाम् ( आश्विन ), on the eighth night when the star is मूलम् and the Sun is in the zodiac of कन्या if there is the touch of नवमी , it is called अघार्दननवमी or महानवमी

Worship could be conducted on the days mentioned, by consecrating the goddess दुर्गा in nine temples or in one temple only. When the goddess is consecrated in nine temples they are meditated upon as nine separate beings. In such cases Goddess दुर्गा should be consecrated with eighteen hands and the rest of the goddesses with sixteen hands. Of the eighteen two should be holding Antimony and डमरु (a small drum shaped like an hourglass), and the remaining sixteen hands should hold weapons that the other goddesses hold. The nine goddesses to be worshipped are रुद्रा , चण्डा , प्रचण्डा , चण्डोग्रा , चण्डनायिका , चण्डवती and चण्डरूपा and in the middle of these eight beings the great goddess दुर्गा who is उग्रचण्डा and the slayer of महिषासुर . दुर्गा is addressed with the spell of ten letters " ओम्, दुर्गे दुर्गेक्षिणि स्वाहा . " Adoration, offering to ancestors and exclamation in sacrifice (Namaskāra, Svadhākāra and Vaṣaṭkāra) should be denoted by six words and the अङ्गस् (organs) beginning with heart also should be imagined. This rootspell should be repeated resting the organs such as heart etc. on the fingers. He who repeats this secret spell of goddess, will never be troubled by enemies.

The goddess should be worshipped by meditating upon her as carrying the weapons such as कपाल (skull), खेटक (shield) घण्टा (bell), Mirror, तर्जनी , bow, ध्वज (flag), डमरु (drum) and पाश (rope) in the left hands and शक्ति (dart) मुद्गर , trident, वज्र , sword, spear, conch, wheel and शलाक (antimony) in the right hands. These weapons also should specially be worshipped.

In the worship of the goddess, a cow (sacrificial animal) should be beheaded with a sword repeating the spell कालीकाली and the blood and flesh of that cow should be offered as oblation to the goddess पूतना uttering the spell, कालीकालीवज्रेश्वरी , लौहदण्डायै नमः . Offering to पूतना should be made in the south west corner of the shrine of the देवी . In the same way offerings of blood and flesh should be made to the goddesses पापराक्षसी in the North West corner, चरकी in the North East corner and विदारिका in the South East corner. The same form of offerings should be made to the god महाकौशिक in the south East corner. The King should bathe in front of this god महाकौशिक and making an image of his enemy with rice flour, should break it. Then give that rice flour as oblation to the gods स्कन्द and विशाख and worship the female ancestors such as ब्राह्मी and such others in the night. As ordained in the वेदस् , the देवी should be bathed in पञ्चामृत (milk, curds, butter, honey and water) and then worship before her, uttering the spell " जयन्तीमङ्गलकाली , भद्रकाली कपालिनी , दुर्गा शिवा क्षमा धात्री स्वधा स्वाहा नमोस्तुते ".
