This is the idea of spiritual communism. In Bhāgavata these things are stated, how to feel spiritual communism. In the spiritual communism... The present communists, they are thinking of the human being only. And the animals are being sent to the slaughterhouse. Although the human being and the animal is born in the same land... Actually, they are also nationals. National means one who's born in that particular land. So why not these animals, nationals? But because they have no Kṛṣṇa consciousness, they cannot think so broadly. They think nationalism means it is limited to the human being, not to the animals, not to the trees.
But when you become Kṛṣṇa conscious you understand that the trees, the plants the reptiles, the aquatics, the human beings, the beasts, everyone, each and everyone, part and parcel of God. According to their karma, they have got different bodies, the color, as I explained. According to kāraṇam guṇa-sango 'sya sad-asad-janma-yoniṣu (BG 13.22). These things are described in the Bhagavad-gītā. One has got a different type of body according to his karma. Karmaṇā daiva netreṇa jantor deha upapattaye (SB 3.31.1). By karma we create next body.
So this is a great science. People do not know how things are taking place, how there are so many species of life, how one is so-called happy, one so-called distressed. Why one is rich, one is poor. Why there are so many planets. Why some of them are demigods and some of them are human beings, some of them are animals. It is a great science. But there is no cultivation of this knowledge in the modern universities or educational institutions. Perhaps we are the only group of men, we are trying to propagate this science of Kṛṣṇa consciousness. But it is a perfect science to understand the position.
