So this Parīkṣit Mahārāja was hunting, and when he became tired and thirsty he entered in the hermitage home of a sage. Because in those days in the jungles there were many hermitages. Those who wanted to live secluded life in the jungle, in the forest, they would have their home, very small cottage, and their means of living was milk and fruit. They would get fruits from the trees, and the kings would sometimes contribute some cows. So that was sufficient for them. To have some milk from the cow and get the fruits from the trees in the jungle, that was sufficient. That is sufficient still. Anywhere, any part of the world, you can live without any economic problem, provided... There is no question of "provided." Anywhere, you can keep a cow. There is no expenditure. The cow will go out and eat some vegetables and grass, so you haven't got to spend anything for the cow. And when she returns, she gives you milk, nice milk. We are trying to introduce this system in our New Vrindaban scheme.
We are keeping there cows, and that place is in Virginia, Moundsville. It is about three miles away from any city or any citizen approach. But they are living very nicely, depending on some vegetables, fruits, and cow's milk. So actually, a man can live very peacefully and healthy life. Not only peacefully. If you are healthy, if your mind is equilibrium, then naturally you are peaceful. So that was a system for the sages and hermitages, hermits, that they used to live on cow's milk and fruits.
