A hog is eating stool, but he's thinking that "I am enjoying, very nice." He's becoming fat. This is called illusion. You are not happy. Nobody's happy in this material world.

Rotary Club Lecture -- Ahmedabad, December 5, 1972:

So these things are very subtle matters, and we have got very, very scientific, authorized information of these matters. But people have become so degraded. They do not want to take any information of the soul, of the transmigration of the soul, of God, our relationship with God, what is the ultimate goal of life, why we are put into this miserable condition of life. Janma... You may say that "I am very happy." I may say, "I am very happy." But actually, there is no happiness. How there can be happy? Janma happiness? Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). Actually who is in knowledge, he should know, "Where is happiness? I do not wish to die; I am dying. I do not wish to be diseased; I am diseased. I do not wish to become old; I am becoming old. So where is my happiness?" This is called māyā. There is no happiness, but still, he's thinking that he is in happiness. This is called illusion. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). So this is... Just like the animal is in illusion. A hog is eating stool, but he's thinking that "I am enjoying, very nice." He's becoming fat. This is called illusion. You are not happy. Nobody's happy in this material world. Therefore the inquiry should be... That is the Brahma-sūtra. That is the Vedānta-sūtra: athāto brahma jijñāsā. Athāto brahma-jijñāsā. This human life is for understanding Brahman. What is that Brahman, Absolute Truth? That is required. If you are simply engaged, animal-like, eating, sleeping, mating, then where is the distinction between animal and us? There is no such distinction. So this Kṛṣṇa consciousness movement is very, very important movement.
