You boys are first-class brahmanas, and I am satisfied with you. May all your desires be fulfilled, and may the Vedic mantras you have learned never lose their meaning for you, in this world or the next.
Cooked food left sitting for three hours is called yata-yama, indicating that it has lost its taste, and similarly if a devotee does not remain fixed in Krsna consciousness, the transcendental knowledge that once inspired him on the spiritual path will lose its “taste,” or meaning, for him. Thus Sandipani Muni blesses his disciples that the Vedic mantras, which reveal the Absolute Truth, will never lose their meaning for them but will remain ever fresh in their minds.
