Scholars who incessantly contemplate on acquiring strength and knowledge should also consider it their moral duty to impart knowledge to the ignorant, so that they can develop their mental faculties. This would automatically lead to the latter’s self-development and spiritual progress.

True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance… To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
