Everyone is envious. If his neighbor, if his brother, if his friend becomes more prosperous than himself, he becomes envious. This is material nature. Similarly, in our Kṛṣṇa consciousness movement, if we become envious, "Oh, my Godbrother, oh, he has become so popular. He is making so much progress. So put some impediments towards his progressive path," this is also material. The Vaikuṇṭha consciousness is that if your neighbor, if your brother is prosperous or progressive, then one should think, "Oh, he's so nice that he has served God so nicely. God is so pleased upon him that he is making so nice progress." That is Vaikuṇṭha consciousness. And material consciousness is that "Oh, he has advanced so much. Oh, let me check him." This is material. That is going on.
The whole world, enviousness. I remember in, long ago, about sometimes in 1936, my eldest son in Bombay—he was in school—he stood first. So his class friends became envious that "Here is a boy, he is coming from Bengal, and he has stood first." They wanted to fight with him. My son came and complained to me that "This is the position." Just see. Children even, envious. You see. That means this is the nature of this world. If you prosper, then your brothers and your neighbors, your friends, will be envious.
