19. Then on the left (north) side (he places one), with (Vajasaneyi Samhita XV, 17), “This one on the left, of ever flowing blessings;” on the left is the sacrifice; and as to why he speaks of it as 'on the left,' it is because the sacrifice is performed from the left (north) side; and as to why he speaks of it as 'of ever-flowing blessings (samyadvasu),' they do indeed flow together (samyanti) to the sacrifice, thinking, “this is a blessing;”—“and Tarkshya and Arishtanemi, his commander and chieftain,” these are the two autumn-months; 'and the nymphs Vishvaci (the all-inclined) and Ghritaci (the ghee-inclined),'—“quarter and intermediate quarter,” said Mahitthi, but they are the vedi (altar) and the offering-spoon, for the altar is all-inclined, and the offering-spoon is ghee-inclined;—“water the shaft, wind the missile,”—water indeed is here the shaft, and wind the missile, for from this side it blows hot, and from that side cold;—“to them be homage . . .!” the import of this has been explained.
