Acquiring knowledge is different. Possessing a discriminative mind is different.

Knowledge itself is burden if we do not possess discriminative mind. Knowledge is like curd. Discriminative mind is like butter. Discriminative mind originates by churning knowledge. Many become arrogant and egoistic by becoming knowledgeable.

The knowledge we acquire and possess must develop discriminative mind. Then knowledge is useful. 

If the knowledge we acquire makes us egoistic it is useless.

Discriminative mind is truth-finder and peace-giving.
