Another analogy:
There was a frog who was trapped in a well. Dr Frog. One day another frog jumped into his well. This frog was from the ocean. Dr Frog was an expert in his well, so asked the new frog how big is the ocean is it 10x the size of my well 20x, 30x. In this way Dr Frog could never really understand what is the size of the ocean.
In the same way we are trapped in our well of perception and we try to understand Reality in relation to our limited perception. The only way we can really understand Reality is to hear from Higher Authority.
We are not only limited by our perception but by our experiences as well. This is true of everyone. Why are your perceptions and experiences to be trusted by me. Am I supposed to just take your word that your an expert.
