To the north of the fire, on kuśa grass with the tips pointing eastward, or in a clean place, he pours out water, saying: 'Let the lord of the divine serpents be led forth; let the divine serpents be led forth!' He sweeps around with a hood-like comb, saying: 'Let the lord of the divine serpents comb; let the divine serpents comb!' He pours out the vessels of the serpent, saying: 'Let the lord of the divine serpents anoint himself; let the divine serpents anoint themselves!' He offers flowers, saying: 'Let the lord of the divine serpents be well-minded; let the divine serpents be well-minded!' He offers a thread of yarn, saying: 'Let the lord of the divine serpents be clothed; let the divine serpents be clothed!' With a young shoot of kuśa grass he strikes into and applies collyrium, saying: 'Let the lord of the divine serpents apply collyrium; let the divine serpents apply collyrium!' He causes them to look into a mirror, saying: 'Let the lord of the divine serpents look; let the divine serpents look!' In the same way for those of the atmosphere and those of the earth, and for the divine ones, three times each, higher and lower; striking each time into the boiled rice substance, until the Pratyavarohaṇa rite, he should offer a bali oblation together with water at night, restraining his speech.
