In plain words
Without weighing whether it is night or day, whenever it is needed, you must stand ready to give your help at that moment. Only when you dedicate your body to such service of others, paropakārārtham idaṃ śarīram, does this body find its fulfilment. But today people grow their cleverness greatly. They take these very things to be great qualities. No. No. Truly, the real feelings of Satya that well up and spring from the bond of the heart are themselves our qualities of Satya. That quality is very slight in today's educated man. A man so empty of good qualities, however great the learning he has studied, cannot shine in this world.
If one has little virtue and great learning, what fruit is there, what is he worth? Why ten acres of land that bears no crop? A little good land is enough.
What use is any amount of cleverness that serves no purpose? What use is any number of studies? Even one good quality that holds up an ideal is enough.
Students! Today we must try to show the humility and obedience that befit learning. But today's education makes man merely a slave of the senses. No, no. We must grow into students who master their senses. These four alone are the foundation pillars of this education. Self control, Self satisfaction, Self sacrifice, Self support. When we develop these four, that itself becomes what makes true education shine. Students! Man's mind today is very fickle. Students must, without fail, try to gain the six treasures. They are śama, dama, uparati, titīkṣā, śraddhā and samādhāna. First, śama. What is śama? We must try first of all to restrain the outer senses. The journey of the outer senses. Our eyes long only for outer sight; they do not long for inner sight. The ears listen only to outer things; they do not long at all for the inner sound. Our feet roam only in the outer world; they make no journey at all in the inner realm. In this way the outward-turned senses go on practising, enjoying and experiencing only the outward principle. To restrain the senses that journey outward like this is śama. Then what is dama? It has to do with the inner senses. Manas, Buddhi, citta, Ahaṅkāra. But these four are not visible to man.
