Prabhupada: It is very simple thing, that "I am changing my body, and similarly, I'll change this body." This should be understood by my present circumstances of life, and it is confirmed by the greatest authority, Krsna. Knowledge by authority and knowledge by experience, both things are there. And still, the rascals do not understand. Knowledge is gathered by experience, and knowledge is gathered from the authority. Just like I ask my father, "What is this?" Father says, "This is bell." So this is knowledge. I get it from my father. And by experience, when I push it, it is ringing. So understand, "This is bell." So two sources of knowledge: by practical experience and by authority.
By H.D.G. Srila Prabhupada
