The teacher (guru) should also be adored, with prescribed rites, because where the guru is left unadored, all the rites prove fruitless.—21.

Afterwards, auspicious songs should be sung, conches blown, and the goddesses, adorned with red sandal, red cloth, red flowers, should be worshipped and the devotee should put red pigment and bathing powder on them after bathing them, for, red sindura and saffron are extremely aggreeable to them.—20.
