Concentration can be mastered in dhyaana (meditation) and this will lead to disinterestedness in the results of one's actions, for the actions are not one's own, but God's. The results too are not one's; they are God's. When you become detached from the fruits of your actions, though intent on action (offering to the Lord your skill and energy), then, you attain peace of mind, Prashanthi. If, however, you cultivate attachment to things of the world - houses, bank balance and insignia of power - then, dhyaana (meditation) fails.

- Divine Discourse, January 5th, 1971.

The essence of education is concentration of the mind and not collection of facts. - Baba
