In plain words
Swami has taught you in so many ways, cared for you like little children, given you many comforts and seen you through your education: if you forget the truth of Swami, you will have to forget your very life. Swami has no greed at all, either to be offered gratitude or to take it. This is good counsel spoken for your sake.
Only when you lead an ideal life with honour and dignity will there be any lasting worth, either in your having studied in our college or in the message you give the whole world. So first of all take these two, sacrifice and character, as your eyes. When the young take this path there will be no want of any kind in Bhārata. First of all you must develop faith. Students! I bring My talk to a close in the hope that you will take all these things into your hearts, keep holy thoughts in mind, reflect on them, put them into practice, and so find fulfilment.
