“Advancement of knowledge for eating, sleeping and mating is animal knowledge. A dog also knows how to eat, how to sleep, how to mate and how to defend. If our education extends only to these points (the dog is eating according to his nature, and we are also eating, but in a nice place, with nicely cooked food on a nice table), that is not advancement.” (Shrila Prabhupada, Krishna Consciousness: The Topmost Yoga System, Ch 1)
