In plain words
Through this mirror called Ahaṅkāra that they have set before their eyes, they forget their very humanness. That is why students have to toil hard indeed to raise up this humanness.
A citta free of attachment and hatred, speech untouched by Asatya and the like, a body unsoiled by the mire of sin: these are what we need today. So, to curb man's attachment and hatred, to grow holy good qualities, and to free him from the grip of these three demons called selfishness, envy and Ahaṅkāra, teachers must strive their hardest. Once these three vices enter the heart, humanness can no longer be recognised at all. We must step forward to selfless service.
Trees are doing selfless service. Whether those who praise them or those who hate them come and sit in their shade, the trees give cool shade to all alike and bring them comfort. Rivers and cows too are doing selfless service. Without trees, cows and rivers, society could not live for even a moment. If man, who enjoys his comforts through selfless beings, lives merely as a selfish one, that is simply a dishonour to humanness itself. So man's chief duty is to put the wealth of learning he has earned, or any other riches whatever, into selfless works.
The teacher's property is learning. Teachers must stand ready to make this learning reach the hearts of the students in the right way, with a selfless spirit, for the nurture of qualities that serve the people.
In Bhārata there is no lack of wealthy men, of great men of learning, of great heads of religious seats, and of mighty kings. Though there are people who have reached such holy positions, if they cannot win Śānti and happiness, the root cause is the fault in their conduct! Today Ahaṅkāra and selfishness have entered everyone's heart and have been setting many kinds of obstacles in the way of their divine powers. So the responsibility of purifying the hearts of students to rid them of these vices, and of shaping them thereby into the uplifters of the Bhārata to come, lies on the teachers. Teachers are embodiments of the ideal. They must set out to practise first and then teach the students. As the teachers are, so the students turn out. Teachers are like a “water tank”. Students are merely like a tap. Whatever water we fill the tank with, that same water comes from the tap. So only when holy, selfless feelings are put into the ‘tank’ called the teachers' heart is there room for holy feelings to take shape, to show themselves and to blossom in the taps called students.
Today there are about 5000 Sathya Sai Bal Vikas gurus. If each teacher sets a hundred students right, there is a chance for the country to prosper greatly.
