How can we get perfect knowledge when our senses are imperfect?

From: Shashikant

It said that we recieve knowledge from perfect source. prabhupada himself said many times that although we are imperfect bt as we r repeting the same words of krishna the knowledge is perfect. furthermore anything we manifacture is defective. then when u r preaching, although u r repeting same words bt listeners are always with 4 defect. then cn they take and understand ur perfect knowledge with imperfect senses. afterall they hv to use there senses to undrstand as far as primary level is concern.
