Alongside of knowledge, youth has to cultivate the good qualities of humility, reverence, devotion to God and steadfast faith. He has to engage himself in good works and enjoy them for the sheer elation they confer.
The tongue should be engaged only in speaking the truth, in speaking sweetly and in consuming what is pleasant and wholesome for the body.
Engage yourselves rather in things that will make you immortal and serve your best interests by service to the World !
Engage yourselves in service activity. Consider social service as service to God. This is the best way to earn God's Love.
Engage in those activities which will please God, which you feel and know will please God, rather than in activities which will please you.
