In plain words
Our teachers are already showing fine enthusiasm in such work. But at times some of them feel that the work load is far too heavy. But they must not think that way. There must be more and still more. We must not waste time but taste it. For what must we use the learning we have gained? When we give the learning we have gained to many others and use it rightly, we become people who have done good to many. What does the Veda, too, say? It says: cross over yourself, and help others to cross over. Let us all work together, live together and fight hardships together. That is
Saha nāvavatu Saha nau bhunaktu Saha vīryaṃ karavāvahai
"Saha nāvavatu" means: let us all be together. "Saha nau bhunaktu" means: let us all grow together. "Saha vīryaṃ karavāvahai": let us all live together. See how broadly the Veda has spoken! No one comes to know its meaning. Even those who know it do not use it rightly. As for why we must be together: "Sahasraśīrṣāḥ puruṣaḥ sahasrākṣa sahasrapāt", that is, all heads, all eyes, all hands are God's! So with all these heads, all these eyes, all these feet, it is God alone; keeping this feeling, whomever we serve, we should regard it as service to God; that is its inner meaning. But why did they say "sahasra", only a thousand? The people of the Vedic age were, all told, only in thousands. Today they are in crores. We need not go back that far. Two hundred years ago, when the British entered our country, the people of Bhārata, Bhārata and Pakistan together, numbered thirty-nine crores. Now, if we look, it is seventy-eight crores. Today the whole world together numbers 536 crores.
