Inner - strength of man is in fact the ' CATALYST ' which transforms his animal existence with its incessant involvement in eating, comfort,and SEX into a Mahamanav ( superman, leader, social reformer etc.

Take the field of music:  Singers and instrumentalistics do not become accomplished in a day. They have to make a persistent edeavour to tune in with the octavates. In absence of the practice the musical notes of the vocalists become irractic and fingers of  the instrumentalists lose its coordination. Musical concerts are held on rare occasions, but to make oneself worthy of participation in these conference, the musician has to keep constantly in practice which is nothing but sadhana ( meditation ) An accomplished artist remains indifferent to the reactions of the audience nor does he bother about the remunerations. He feels contented with the pleasure derive from his daily practice itself. A true artist would not find any difference even when he does not get reward or recognition for his art. He would nonchalantly continue to do his music sadhana even while dwelling in a mud hut in the forest without losing interest. Mental make of a person practicing self---- discipline should have at least this much in common.
