Bandi said: Nine is the number of the Mantras used in kindling the fire in a sacrifice to the Pitris: nine are the fixed functions in the progresses of creation, nine letters compose the foot of Vrihati (a meter) and nine also are numbers (in calculation).
बन्धुवाच नवैवोक्ताः सामिधेन्यः पितृणां तथा प्राहुर्नवयोगं विसर्गम्। नवाक्षरा बृहती सम्प्रदिष्टा नवयोगो गणनामेति शश्वत्॥
