In plain words
If you set a feast of five dishes and sweet rice on a plate and say, "Feast of five dishes and sweet rice!", will it go into your stomach? Not even one grain of rice goes in. For the food on the plate to go into the stomach, you must put the hand and the mouth to work. Service with the hand, and with the mouth we must chant the mantra. Only through the sādhana of these two does divinity come to us. Otherwise, without doing any sādhana at all, if you want God to spring up before you, how will He spring up? Not a penny must be spent, not a foot must cross the threshold. Kaivalya must drop into the lap! That is the way of a lazy man. For such lazy people divinity stays very far away. Laziness is rust and dust. Realization is best and rest. We must make the effort it takes to realise.
Toil without morality, wealth without toil, education without character, sādhana without sacrifice, science without humanity, politics without inquiry into the eternal and the passing: these six are great forms of karma for the world. That is why these are the six sins. Because of these sins alone the world is falling into trouble. So some sins are cling… to the world as well. These very six sins torment the world. Science without humanity, that is not science. Education without character, that is not education. It is agitation. Sādhana without sacrifice is no sādhana at all. That sacrifice alone gives immortality. So we cannot reap a harvest without toil. Without tilling, how will we get a harvest? In the same way, commerce without morality, a harvest without toil, education without character, sādhana without sacrifice, science without humanity, politics without morals and rules: these six alone, the six inner enemies, are tormenting the country. These six sins alone are the root cause of the country's fall. If these six sins are absent, that very thing will take shape as divinity. The dust called these sins has covered it over. We must wipe away this dust that has gathered. That itself is the chief duty students must do today. If we do not take part in such work, all our studies become worthless. For everything, Bhakti is essential.
Though they study hard and earn their M.A.s and B.A.s, though they be great men of renown, though they have riches and be given to good charity, though they be virtuous souls who won fame on earth, though long life and health be theirs without a break, though they be men of perfect strength, ever doing japa in plenty, though they be brāhmaṇas who teach the Vedas, they never equal the devotees, not at any time. Without worshipping God, Bhakti does not come. What else beyond this can I make known, O students, good and counted among the virtuous?
