A dog, in such abominable condition, still he's joyful. He thinks, "I am very happy." A hog, any animal . . . we are human beings; we are given better facilities of life. The animals are not given so much facilities by nature, but still, they feel happy. If we say, of course, straight, somebody may be sorry, but this is nature's law. So however abominable condition it may be, one feels that he's happy.
So these two kinds of things are going on, parallel. But actually, everyone who is encaged in this material body, he's unhappy. That is the sum and substance of the whole material existence. In the Caitanya-caritāmṛta it is said, dvaite bhadrābhadra (CC Antya 4.176) sakale samān.
In the dual world, or in this material world, what we have manufactured that, "This is very nice and this is not nice"—this "bad" or "good" conception—he says that it is simply mental concoction. Actually, there is nothing good here. One should be very much pessimistic. Otherwise, he'll have to remain in the darkness of ignorance of this material nature.
One should thoroughly understand that we are in a very precarious condition of this material . . . because they have no information that there is happy life, there is eternal life, there is blissful life. They have no information. They think, "This is the life. So let us adjust things as far as possible." This is the covering energy of material energy.
