In plain words
If, on the other side, we do not give up the food we have eaten, our health declines. On one side we breathe in air. If, on the other side, we do not let out the air we have breathed in, our lungs will be ruined. In one part of our hand the blood keeps flowing. If this flowing blood stays still in that one place, a Boil forms there. So, in every way and in every field, we must stand ready in a spirit that says: tyāga, tyāga, tyāga. When one gives up one's own welfare and keeps the welfare of the world as the aim, our welfare too becomes one with that welfare of the world. So, first of all, when we join this department, we must be ready for many toils, many troubles and many hardships, keep the welfare of the world as our aim and grow in faith in God, and so be prepared in carrying out our duty, our (duties). To have faith in God in this way, to trust in our duty, and so to go on doing our duty rightly: this is the main path; it is the ladder to man's rising. As I see it, discipline is not to be seen anywhere at all. Every officer and every leader keeps saying discipline, discipline, discipline, but the very person who says it has lost his discipline. When we develop this discipline well, we shall carry out our duty well and rightly.
Above all these, “The man of śraddhā gains Jñāna”: we must develop śraddhā. For those who have śraddhā, even what is unattainable is attained. Even things beyond reach come within reach. Śraddhā is a sāttvic trait. Lack of śraddhā is a trait of tamoguṇa. Those who have this trait of tamoguṇa have no tyāga of any kind. Those who have the sāttvic guṇa only ever step forward. Those who lack śraddhā are forever stepping back. This lack of śraddhā is a lazy man's trait. This laziness can never reach the summit called the sāttvic. So if those who have śraddhā are given even a tiny spark of fire, they fan it in many ways and make it grow. Even if those who have no śraddhā are given a basketful of fire, they put it out. The man without śraddhā, though every provision is in his Store-room, does not cook for himself out of laziness, and ends up suffering his own hunger. Those who have śraddhā, though they have no provisions at all, somehow gather food together themselves and eat. So today we must develop śraddhā. Whatever learning we came here to learn, whatever we came to know, whatever we came to practise, we must develop śraddhā in it, and so, without turning aside from our goal, step forward with the aim of being of help to the country. Merely reaching this place, coming and gathering here from distant regions far and wide, and then failing to recognise the learning we must learn, the path we must know and the duty we must do: through this we become not only people who betray ourselves, but people who have betrayed our country too. We are not living for a salary. We must recognise the Satya that we are living for the sake of life. Only when the police and the whole military department take up some kinds of śraddhā for this kind of tyāga will our country have the chance to be protected.
