“The Bhagavad-gita is just like a cow, and Lord Krishna, who is a cowherd boy, is milking this cow. The milk is the essence of the Vedas, and Arjuna is just like a calf. The wise men, the great sages and pure devotees, are to drink the nectarean milk of Bhagavad-gita.” (Shrila Prabhupada, Bhagavad-gita, Introduction)
