What’s wrong with using somebody else’s framework

“I wish that you, oh exalted one, would not be angry with me,” said the
young man. “I have not spoken to you like this to argue with you, to
argue about words. You are truly right, there is little to opinions.
But let me say this one more thing: I have not doubted in you for a
single moment. I have not doubted for a single moment that you are
Buddha, that you have reached the goal, the highest goal towards which
so many thousands of Brahmans and sons of Brahmans are on their way.
You have found salvation from death. It has come to you in the course
of your own search, on your own path, through thoughts, through
meditation, through realizations, through enlightenment. It has not
come to you by means of teachings! And–thus is my thought, oh exalted
one,–nobody will obtain salvation by means of teachings! You will not
be able to convey and say to anybody, oh venerable one, in words and
through teachings what has happened to you in the hour of enlightenment!
The teachings of the enlightened Buddha contain much, it teaches many to
live righteously, to avoid evil. But there is one thing which these so
clear, these so venerable teachings do not contain: they do not contain
the mystery of what the exalted one has experienced for himself, he
alone among hundreds of thousands. This is what I have thought and
realized, when I have heard the teachings. This is why I am continuing
my travels–not to seek other, better teachings, for I know there are
none, but to depart from all teachings and all teachers and to reach my
goal by myself or to die. But often, I’ll think of this day, oh exalted
one, and of this hour, when my eyes beheld a holy man.”

From Siddhartha by Herman Hesse.
