So maintenance cannot be taken by anyone except by God. Therefore this material world is being operated in three departmental qualities: sattva, raja, tama. Sattva is maintenance. Sattva means goodness. Goodness is maintenance. And raja means activity. Without activity, there cannot be any creation in this material world. If you want to construct something, there must be activity. Raja means activity. And tama means darkness. So these, these qualities are working. These qualities are working. Now, in your country, by the rajo-guṇa you have created so many things, a nice country, very nicely operating. But another side: the confusion is there, the hippies. You see? Future hope of the country is very dark. You see? It will spoil the whole thing if the country's not alive to the situation. This is another way of protest. Just like in Europe there are, in Russia there is communist, so this is another way of... So these qualities will work because this material world—one side, goodness; another side, darkness; another side, activity. This is going on. So as there are so many departments of activities, all these demigods, they are in charge of, director, director in chief. So brahmādayaḥ. Brahmā is in charge of something. Indra is in charge of something.
The demigods, they're officers. They have no information. They say, "It is nature, nature, nature, nature." No nature. They are department, department. Indra is in charge of this cloud, how cloud is conducted, how rain falls there, and he's in charge of... Water department, like that. Just like moon. Moon is in charge of lighting at night. Sun is in charge of lighting in daytime. Because it is darkness. The whole world is darkness. So these demigods... Similarly, Lord Śiva is in charge of destroying, tamo-guṇa. When there will be necessity of destroying this whole thing... Because this world is like that. Everything that is created, that must be destroyed. Your body is being created from the father and mother. Now it is being maintained. So creation and maintenance, and then a time will come—it will be destroyed. So these, these three departments are there. So for creative department of this material world, Lord Brahma; for maintenance department, Lord Viṣṇu Himself; and for destruction, Lord Śiva. These are the guṇa avatāras, three, trinity. One is creating, one is maintaining...
