Dhruva Mahārāja, at the age of five years old, he left his father's home, went to the forest, and with determination he saw God, Kṛṣṇa, within six months. But after coming back, when he was older, when he became king, oh, he was so powerful that there was some mischief done by the sons of Kuvera, he killed them like anything. You see? He killed them like anything, so that the Kuvera personally requested that "Mahārāja Dhruva, I know that they are criminals, you are doing your duty as king, but I request... Otherwise my whole dynasty will be finished." So immediately, Dhruva Mahārāja accepted a great man's request, Kuvera. And this Kuvera being so satisfied by the behavior of Dhruva Mahārāja that he was prepared to give him any benediction: "My dear king, you can ask me, from me, any benediction you like. You have kept my request." So what Dhruva Mahārāja asked him? He was Kuvera. Kuvera means the treasurer of the demigods. If he wanted that "The whole treasury of the universe should to given to me," he would have given him. But what he asked? He asked, "My dear sir, you are so kind, you are prepared to give me all benediction. Please give me this benediction so that I may be attached to the lotus feet of Kṛṣṇa."
This is kṣatriya. If required, they'll fight and finish the whole opposite party. Otherwise they are devotees. Just like Arjuna. Arjuna, a kṣatriya. Not that Arjuna was coward. He was sympathetic: "Kṛṣṇa, what is the use of this fighting? The other party, all my relatives, if I kill them, then what do I gain?" Actually, that is the fact. We work so hard, accumulate money for showing to our relatives, to our friends: "Now, just see how I have become rich." "But if they are all gone, then whom shall I show this kingdom?" Thinking like ordinary worldly man. But he was not a coward. Not that he was hesitating to fight, but when he understood that "Kṛṣṇa wants this fighting. Oh, that's all right." Then Kṛṣṇa asked him, "My dear Arjuna, what is your decision?" "Yes." Kariṣye vacanaṁ tava (BG 18.73). "Yes, I shall fight." This is Kṛṣṇa consciousness. "Kṛṣṇa wants this fighting. I do not want. I have nothing to... What is my value? Kṛṣṇa wants it. That is value." This is kṣatriya. So finished—the whole grandfather and grandchildren and everything, finished. The other party, Kauravas, not a single person lived.
