Swami Rama tells this story:
"There was once a swami who used to teach students every day. One of
the students listened attentively and heard the swami speaking about
vairagya, the philosophy of non-attachment, and the student took off
for a forest dwelling and there, he was enlightened.
"After dwelling there for twelve years, he wondered what had happened
and what had been the fate of his friends, with whom he used to
learn. So he returned to that place, and everyone was still sitting
there exactly like before, and the swami was still lecturing.
"What a waste of time!
"The point is that you don't need much external information; you
already have true knowledge within. You need to learn how to apply
the knowledge that you have.
"You are taught: 'Be good, be nice, be gentle, be loving.' You have
all been taught that, but you should learn to practice, understand,
and to apply that knowledge to yourself. You need to understand how
you function, and the process that results in your actions."
