The very character of sacrifice which sacrifices have, depends upon ghee. Cows have been said to be the limbs of sacrifice. They represent sacrifice itself. Without them, there can be no sacrifice. With their milk and the Havi produced therefrom, they uphold all creatures by diverse acts.
Cows are guileless in their behaviour.
From them flow sacrifices and Havya and Kavya, and milk and curds and ghee. Afflicted by hunger and thirst, they bear diverse burdens. Among all objects mobile and immobile, the mobile are superior. Among mobile creatures Brahmanas are superior. The sacrifices are all established upon them.
