Disciple: But, sir, how many monks are to be found who are truly devoted to the good of men?
Swamiji: Ah, quite enough if one great Sannyasin like Shri Ramakrishna comes in a thousand years! For a thousand years after his advent, people may well guide themselves by those ideas and ideals he leaves behind. It is only because this monastic institution exists in the country that men of his greatness are born here. There are defects, more or less, in all the institutions of life. But what is the reason that in spite of its faults, this noble institution stands yet supreme over all the other institutions of life? It is because the true Sannyasins forgo even their own liberation and live simply for doing good to the world. If you don't feel grateful to such a noble institution, lie on you again and again!
