Krishna is the Goal of the Vedas

On February 15, 1970, Srila Prabhupada wrote to Dr. Staal, ?The unhulled rice and the empty husks of rice look very much the same. One who knows how to get the grain out of the unhulled rice is wise, but one who beats on the empty husk, thinking to get some result, is simply wasting his labor uselessly. Similarly, if one studies the Vedas without finding the goal of the Vedas, Krishna, he simply wastes his valuable time.?
