knowledge

"Knowledge should mean a full grasp of knowledge.
Knowledge means to know yourself, heart and soul.
If you have failed to understand yourself,
Then all of your reading has missed its call.
What is the purpose of reading those books?
So that man can know the All-Powerful.
If you have read, but failed to understand,
Then your efforts are just a barren soul."
Understanding shouldn't only come through our minds,as Molana says we must get every thing with our hearts, inwardly.Our morality has better understanding than the brain.The things we've understood with heart remain much more.Our heart never dies,but our brain may die. What raises a man to a higher position are the inner sciences:
There's a story between a grammarian & a boatman:
"A certain grammarian embarked in a boat. That self-conceited person turned to the boatman.
And said, 'Have you ever studied grammar?', 'No', he replied. The other said, 'half your life is gone to naught.'
The boatman became heart-broken with grief, but at the time
he refrained from answering.
The wind cast the boat into a whirlpool: the boatman spoke loud (shouted) to the grammarian.
Tell me, do you know how to swim?' 'No', said he, 'O fair-spoken good-looking-man!'
'O grammarian,' said he,' your whole life is naught, because the boat is sinking in these whirlpools.'
Know that here mahw (self-effacement) is needed, not nahw (grammar): if you are mahw (dead to self), plunge into the sea without peril.
The water of the sea places the dead one on its head (causes him to float on the surface); but if he be living, how shall he escape from the sea?
Another of Molana’s advice about knowledge is that knowledge makes its owner gain a high esteem when it is united with good deeds. it is not sufficient to be knowledgeable (Fihi Mafih, 93). Those who are knowledgeable but devoid of good deeds are not scholars but only knowledge keepers (Masnavi, III/3060). What is understood from this thought is that Mevlana favours that theoretical knowledge should be applied to life. Knowledge should never be kept in words and theory, but to be applied to life, to be lived with.
