Kṛṣṇa consciousness includes varieties of activities. They, in..., the press representatives they asked me, "Whether your students, do you take part in politics? Is it sanctioned?" Why not? Our Bhagavad-gītā is produced in battlefield, in battlefield. So why should I deride battle? No. When there is need for fighting, there must be fighting. This world is like that. Otherwise there is no need of fighting. But there is a class of men who will fight. Still it is existing. When there is fight, those who are meant for military purposes, they fight. Not the civilians go and fight. No. Similarly, in the society, there must be divisions. Not that everyone should be called, "Come on, you go to fight." Where is his training? That was not the system. First of all, cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13). These children, according to strict Vedic principle, by practical psychology, they should be tested, "What is the tendency of this boy?" There can be four kinds of tendencies: brāhmaṇa, kṣatriya, vaiśya, śūdra. Some child is to become a brāhmaṇa, some child is to be become a kṣatriya, some child is to become a vaiśya, and the rest, śūdras. They do not... Śūdras does not require any training. Śūdra means no training. Ordinary worker class. Otherwise other three, especially two, namely the brāhmaṇas and kṣatriyas, they require very magnificent training. Because they will administer the whole affairs of the society.
So brāhmaṇas, they would give advice to the kṣatriyas, and kṣatriyas, according to their advice, would rule over the citizens. This was the system. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). Vibhāgaśaḥ, "by division of quality and work." A brāhmaṇa must be qualified and at the same time work as a brāhmaṇa. So we are training, especially, our students to become qualified brāhmaṇas. We cannot take up all other department. Similarly, others may take up the line of training... Military men... Others may take... There are training classes. Maybe mercantile firm, you can get your lessons. So there was organized method to train these mercantile men, administrator and brāhmaṇa.
