Prabhupāda: The kṣatriyas, they are royal class, they possessed land, so they had obligation to protect the country. Therefore they were fighting. How nice arrangement. Those who are occupying administration of the country, they should fight. But they are sitting very nicely in their armchair and calling somebody, "Go and fight and be killed." This system is not scientific system. Therefore the caste system is very nice. They have now been condemned... Not condemned, but they want to revise it. But this is a very scientific system. Why? It is created by Kṛṣṇa. Kṛṣṇa says in the
Bhagavad-gītā: cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). "I have created the four divisions of caste." It is not exactly caste; section, varṇa. So how you can stop? It is natural.
