So present crisis, food crisis . . . everything is described in the Bhagavad-gītā. Bhagavad-gītā does not say that, "You live by breathing air." No. Bhagavad-gītā says, annād bhavanti bhūtāni (BG 3.14). Anna. Anna means food grains. There is necessity of food grain. Annād bhavanti bhūtāni. Bhagavad-gītā never says that, "You don't require to eat. You simply breathe air and practice yoga." No. But we must eat neither more nor less. That is recommended. Yuktāhāra-vihārasya. We should not eat more nor less. And nirāśīḥ. Nirāśīḥ means desireless of extravagance. Now we are desiring for sense gratification more and more. That is not wanted.
If you want perfection of life . . . this is called tapasya. One has got the desire, but he should not desire unnecessarily. Everyone has got the right to eat, even the animals. Everyone has got the right. But because we are desiring to enjoy more, therefore we do not give the chance to the animals to live properly, rather we are trying to eat the animals. This is not required. This is called nirāśīḥ. Why you should eat animals? That is uncivilized life. When there is no food, when they are aborigines, they may eat animals, because they do not know how to grow food. But when the human society becomes civilized, he can grow so many nice foods, he can keep the cows; instead of eating the cows, he can get milk, sufficient milk. We can make so many preparation from milk and grains. So we should not desire unnecessarily to enjoy more.
