In plain words
In every man there is the individuality to recognise such a truth. Not only that. There is another reason. The human body has five kośas. The annamaya kośa, the prāṇamaya kośa, the manomaya kośa, the vijñānamaya kośa, the ānandamaya kośa. But the fourth, the vijñānamaya kośa, is known to man alone, and not to cattle, birds, beasts and the rest. That is precisely why man has gone on growing into so great a man of knowledge, a genius. In man there is the individuality to recognise such a truth. The power of discrimination, of what is good and what is bad, what is fit to be done and what is not, man alone has. Man has the power to show plainly, ‘This is for self, this is for others.’ If we go on examining in this way, the divine power in man cannot be said to be this much or that much. Where is the earth, where is the moon? From where did the strength and skill come to travel from the earth to the moon? This is his own power of intellect! The power of knowledge itself! But does everyone have this power? No. That power is visible to only a few. Some people have japa-mālās in their hands. The thread in that japa-mālā does not show on the surface. Yet without the thread the beads cannot stay. But in time this thread in the mālā comes into view.
If we want to make the heart pure, we must serve
Only in a pure heart does the sacred divine feeling become visible to us. So, if we want to make the heart pure, we must serve. That is precisely why Vedānta said, ‘Cittasya śuddhaye karmaḥ.’ When we perform sacred actions, purity of citta comes about. When purity of citta comes about, purity of Jñāna arises. When purity of Jñāna has arisen, ‘Jñānādevatu kaivalyaṃ.’ So we must serve. For whose sake are we serving? If you do not serve, the world loses nothing at all. You must not think, ‘By my service I am bringing about uplift.’
