Those who take Krishna's advent as that of an ordinary man are great fools, but if one can simply understand the transcendental nature of this event  as well as His disappearance, he becomes immediately liberated.
Correspondence, Vrindavan, August 1967

Anyone who has a natural tendency for rejecting sense-gratification is considered to be advanced or liberated in spiritual life. Your appreciation of Maya as false and Krishna as the only reality is a great asset.

Nobody has ever gained anything by becoming a tool in the hands of Maya, but everyone has become eternally happy by serving Krishna.

Now, there are so many scientists. They are discovering vitamin value from foodstuff. Now, what is the vitamin value in the dry grass? Can any scientist say that this is the vitamin value in dry grass? If there is no vitamin value in dry grass, how the cow is producing so much milk, who is full of vitamins A and D? How, from dry grass, vitamins coming out? Nowadays the physician prescribes some artificial vitamins for maintaining your body. Now, what is the vitamin there in the dry grass so that the cow is eating dry grass and giving you nice milk full of vitamins A and D, essential for your life? So these are all wrong theories, that "This contains this vitamin. This contains this." Let them go on. But natural foodstuff which is meant for human being, they are full of vitamins already there by nature's law, by God's wish.
