Three Ways That Sense Perception Is Limited

“Man's knowledge should be developed to explore the technology which deals with the difference between a living man and a dead man, a living body and a dead body. That spiritual knowledge was taught by Krishna in the beginning of Bhagavad-gita. Arjuna was talking to Krishna as a friend. Of course, whatever he was saying was right, but it was right only to a certain point. Beyond that point there are other subject matters of knowledge, which are called adhokshaja because our direct perception of material knowledge fails to approach them.” (Shrila Prabhupada, Krishna, the Reservoir of Pleasure)
