By His Divine Grace A.C.B. Swami Prabhupada
A kshatriya never goes back from the promise, never refuses any challenge. If a kshatriya is challenged by somebody, that “I want to fight with you,” oh, he cannot refuse. This is kshatriya spirit. He cannot say that “I am now busy.” Suppose somebody comes to you, that “I want to fight with you.” You may say, “What nonsense fight? I have no time. We are in the temple.” But a kshatriya cannot deny that. A kshatriya at once must accept. “Oh, yes. Come on.” And the weapon should be, if he has no sword or weapon, he should be supplied weapon and fight. This is kshatriya spirit. They were highly charitable and chivalrous and keeping promise and with a great tendency for ruling over. They shall rule over.
