In general we may think we are an ideal disciple. But that is not true. An ideal disciple of fully surrendered to a Guru ( who has a body ).
Suck a disciple instantly understands everything the Guru says in a word or sentence
Take the previous example of Ramana. He made a simple statement of name and form. Actually the depth is instantly recognized by a true surrendered disciple or by another enlightened person.
So how is it that one word of a Guru and disciple instantly gets the meaning enough to fill an encyclopedia? Simple. Both are beyond the concept of time. So it may seem instant to us.
This is a deep secret between Guru Shishya. Extremely rare to find this
