Modern Kshatriya

People with a poor fund of knowledge do not know the difference between the death of a devotee and the death of a nondevotee. In this connection, an example can be given: a cat carries its kittens in its mouth, and it also catches a rat in its mouth. Superficially, the catching of the rat and the kitten appear to be one and the same, but actually they are not. When the cat catches the rat in its mouth it means death for the rat, whereas when the cat catches the kitten, the kitten enjoys it. (Prabhupada purport SB 4:12:30)

"Even when there are reasons for grief like separation from beloved ones, the enlightened one’s mind is not perturbed. He has no craving for sense enjoyment, he has no hankering for them. He is free from desire, fear and anger;— desire is craving for objects not yet obtained. Fear is mental agitation produced by the awareness of factors which cause separation from objects that one loves, or by encountering that which is undesirable. Anger is a disturbed state of mind which produces aggression directed at another sentient being who is perceived as the cause of separation from the beloved object or when confronting what is undesirable. An aspirant of this sort, who constantly meditates on the atman, is said to have attained steady intellect." (Ramanuja Acharya, Gita Bhashya, 2.56)

for when people here were without a king and fleeing in all directions out of fear, to protect this whole world the Lord created the King by extracting eternal particles from Indra, wind, Yama, Surya, Agni, Varuna, Chandra (Moon), and the Lord of Wealth. The Law Code of Manu

After properly settling the country and building a fort according to textual norms, a king should direct his maximum effort constantly at the eradication of thorns. By protecting those who follow the Arya way of life and by clearing the thorns, kings devoted to the protection of their subjects reach the highest heaven... Bribe-takers, frauds, cheats, gamblers, those who live by abjuring good luck, fortune-tellers, corrupt high-officials... The non-Aryans wearing the marks of an Arya... should be identified as thorns on his people's side. - The Law Code of Manu

We try to conquer many things - even empires - but if we fail to conquer the mind, we are failures even if we manage to conquer an empire. Srila Prabhupada

"Lord Brahmā chastised the demigods for not properly respecting this brāhmaṇa, who was their guru." Śrimad Bhagavatam 6.7.21, Purport.

The truth is that man has gained nothing from the progress of science and technology, neither in regard to knowledge (and I have already spoken of that), nor in regard to his own power, and still less in regard to any higher law of conduct. At best, one could make an exception for medicine, but still only on the physical level. As for power, let no one claim that the ability of the hydrogen bomb to destroy an entire metropolis, or the promise of nuclear energy that heralds the “second industrial revolution,” or the games for grown-up children that are space exploration, have made a single person more potent and superior in himself, in his concrete being. These forms of a mechanical, external, and extrinsic power leave the real human being untouched; he is no more powerful or superior using space missiles than he ever was when using a club, except in its material effects; apart from those he remains as he was, with his passions, his instincts, and his inadequacies.
