In plain words
He must give his services free. He must put this medicine he has learnt to the right use, an unselfish use, for these poor people. Then, those who are lawyers: when the powerless are caught in some trouble, they must give up their own selfishness and take up, free of charge, the work of clearing those troubles that are theirs to deal with. A trader. From what he has, he must look to some extent to a way of getting an income, and the rest he must payōgiṃcāli for charity and good works. In this way learning must be brought into the service organisations. But, unfortunately, nowhere today are these three kinds of path to be seen. Whether doctors, lawyers or traders, they look only to their own earning of money as the chief aim, and do not look at all to the welfare of the people. With money earned by oppressing others, no one can know happiness and joy. So it is only from money earned through right use that happiness and joy come. Money earned by tormenting others goes on tormenting. People must recognise this truth and take part in service to society. When we wish to know peace and security in our future, we must use our strengths to good purpose. So service is the chief sādhana.
Even without doing any japa, any sādhana or any yoga, there is truly a chance through service to recognise the divinity of the Paramātma and the principle of Prema. This service proves the unity in diversity. That is why, when we wish to recognise the divinity in all, service to the people is itself the right sādhana: we must provide facilities for education and medical care, and bring fitting help to the helpless and those who have no one. Living for oneself is no greatness. Only a life lived for others is true life. Nowhere at all, in this age or in this world, is there any such thing as man living by himself alone. Without the encouragement of society, and without his recognising the conditions of society, it is hard for man to live. Man is born in society itself, lives in society itself and ends in society itself. So the duty is this alone: to give such a society the gratitude it deserves.
