This is a worship conducted to prevent epidemics. In olden days महाविष्णु advised नारद on the form of this worship. The form of this worship is given below:

In the centre of the circular lotus, consecrate वासुदेव with the first syllable of mantra (spell) 'A'. To the south of him consecrate and worship सङ्कर्षण and प्रद्युम्न with the syllable 'Ā'; in the S.E. corner, अनिरुद्ध with the syllable 'Aḥ'; in the west, नारायण with the syllable 'Om'; ब्रह्मा in the N.W. corner with the syllables 'Tatsat'; विष्णु in the North with the syllable 'Hum'; नृसिंह with the syllable 'Kṣau' and वराह in the N.E. corner with the syllable 'bhūm'.

Consecrate गरुड with spells having as first syllables 'Kam', 'ṭam', "sam" and 'śam' at the western entrance of the lotus figure; पूर्ववक्त्र , with syllables 'Kham' 'cham', Vam' and hum' at the southern entrance of the lotus figure; गदा (club), with the syllables 'Kham', 'ṭham' and 'Śam' at the Northern entrance; consecrate ईश with the syllables 'bam', 'ṇam', 'mam' and 'Kṣam, in the North East corner. Then consecrate श्री with the syllables 'Dham', 'Dam', 'Bham' and 'Ham' on the southern side; वनमाली with the syllables 'Gam', 'Ḍam' 'Vam' and 'Śam', on the northern side; श्रीवत्स with the syllables 'sam', 'ham' and 'lam', to the west of वनमाली ; and कौस्तुभ , with the syllables, 'cham', 'Tam' and 'yam', to the west of श्रीवत्स .

After having consecrated and worshipped persons as mentioned above, in the order of the ten member-parts of महाविष्णु , अनन्त should be consecrated below the seat of the deity and in the order of the ten member parts of अनन्त , the four component parts called महेन्द्र and so on should be consecrated on the four directions such as east and so on, and consecrate in the same way all the decorations, flags, canopy etc. Then the three spheres of वायु (Air), अग्नि (fire) and इन्दु (moon) should be consecrated with the first syllables of the spells suited to each and meditating on them and worshipping them, dip the body in the meditation. Then imagine that the subtle form of the individual soul is staying in the sky. Then meditate that the individual soul is reborn by harmony with the universal soul after having been dipped and washed in the snowwhite ambrosia emanating from the moon. After that saying to yourself 'I am विष्णु himself reborn", utter the twelve-syllabled mantra or spell. Place heart, head, turban and weapon respectively on chest, head, hindpart of the lock of hair and नेत्र (eye) Place weapons in both hands. After this your body will become divine. This placing of the individual soul should be repeated in the same way with देव (god) and शिव . When this worship of विष्णु is conducted in heart in imagination (without the aid of materials) it is called ' अनिर्माल्यपूजा ', and when it is done with the aid of lotus figure etc., it is called सनिर्माल्यपूजा .

At this पूजा (worship) the disciple should stand with eyes tied. Then on whichever deity he places flower it should be given that name. Place it on the left side and burn gingelly, paddy and ghee in the sacrificial fire. After performing hundred and eight burnings perform another burning for the purification of the body. To each of the member-parts of the नवव्यूह deities also burnt offering should be made, no less than hundred times to each. Then put the entire thing in fire as burnt offering. Then the disciples should take fast, and the disciples should offer wealth etc. to the teacher. (Agni Purāṇa, Chapter 201) .
