A scholar who contributes nothing to the edification of his community is like a fresh fruit just sitting in a basket to only rot itself in the end and is in fact working against the welfare of his society, and above all himself . He is like a like a flying cloud overhead which gives a false hope and then fly away without pouring a single drop of water only to shed itself in an ocean where it will only annihilate itself and the very purpose of its very being: to feed the circle of life. He is like a drunkard who have all the fantasies of grander and magnificence only to find himself in some pathetic state next morning. He is like a mule laden with the all the books of antiquity and present. As emotions without thoughts lead to nothing such is knowledge without passion of benevolence and sharing.
