The society must be divided into four classes of order. There must be intelligent class of men, who are called brāhmaṇas. They must give spiritual education to the society. Not that everyone should remain laborer and work hard day and night like hogs and dogs for sense gratification. It is a very dangerous civilization. You cannot expect any peace and prosperity in this type of civilization.Therefore this Kṛṣṇa consciousness movement is very, very essential. Very, very essential. I am very glad to inform you that this movement is being especially received in the Western country by the younger generation. I am very much hopeful. I am old man of seventy-six years' age. Now, I can pass away at any moment, but I am confident my disciples, who are mostly Europeans and Americans, they will continue this movement, and I wish there will be considerable change on the face of the globe.
