Prabhupāda: In the Īśopaniṣad, it is said, pūrṇam adaḥ pūrṇam idaṁ pūrṇāt pūrṇam udacyate (Īśopaniṣad, Invocation). In the creation of Kṛṣṇa, there cannot be any scarcity. Everything is sufficiently there. Pūrṇam, it is complete, perfectly made, either this planet, that planet. Everywhere, the living entities are there, and Kṛṣṇa has made provision for every one of them. There is no question of scarcity. But people are not obeying the orders of Kṛṣṇa or the authorities, that "You produce..." Annād bhavanti bhūtāni (BG 3.14). Even in Bible, it is said, "Thou shalt not kill." They are not producing food grains, and they are killing the animals and eating.
How they will be happy? It is not possible. Most sinful activities. You produce your food. The bull will help you. And the cows will supply you milk. They are considered to be father and mother. Just like father earns money for feeding the children, similarly, the bulls help producing, plowing, producing food grains, and the cow gives milk, mother. And what is this civilization, killing father and mother? This is not good civilization. It will not stay. There will be catastrophe, waiting. Many times it has happened, and it will happen because transgressing the law of nature, or laws of God, is most sinful. That is sinful. Just like you become criminal by transgressing the law of state, similarly, when you transgress the law of God, then you are sinful.
