Cetas, everything is working within the heart, the whole thing. Heart is the central point of this body. So when the heart is not punctured by the rajo-guṇa and tamo-guṇa, and you become situated on the modes of goodness, then you become jubilant. Jubilant means he can understand at that time that "Why these people are working so hard like cats and dogs?"
The human life is meant for understanding what is God. Athāto brahma jijñāsā. This life is meant for simply understanding what is God. The animal life, they cannot understand. That life is different. But the human life is developed, consciousness is developed. He can understand. This is called goodness. Tasyaiva hetoḥ prayateta kovidaḥ.
How one becomes intelligent? He can study . . . when he is on the platform of goodness, he can study the nature that, "Why I shall work so hard for getting all my material necessities?" This is being supplied by nature. The birds and beast, they are getting their food, they are getting their mates, they are being protected in their own way; they have got a sleeping nest, apartment. So even an animal, even a small ant . . .
We sit down in the garden, we see, even the small ant it has got family, it has got home, it has got eating. Everything is there, from ant to the elephant. Who is supplying? They have no business. They do not do any business. They have no profession. But they are getting their necessities of life.
