Many postpone sadhana (spiritual discipline) to old age. This is wrong. Earn the precious reward while you are young and fresh. It is never too soon to begin. The tongue, the eye, the ear, the hand and mind should all be trained from childhood upwards to avoid evil. If these are kept clean and holy, the grace of God is won. When the flesh urges you to fall into falsehood, do not yield, stand firm. When the individual is strong and steady, the family prospers; when the family prospers, the village is happy; when the village is happy, the country is secure and strong; when countries are strong and secure, the world is full of humility and reverence, charity and peace. Sing aloud the glory of God and charge the atmosphere with divine adoration; the clouds will pour the sanctity through rain on the fields; the crops will feed on it and purify and fortify the food; the food will induce divine urges in man. This is the chain of progress. This is the reason why I insist on group singing of the Names of the Lord.
