Let me take one instance which seems to be the most hopeless of all--the instance of war. What can be more inhuman than war, what more brutal and more terrible, stirring the angriest passions of man and making him like a wild beast in his rage? Aye, but that is not all. Let us look at the life within a soldier which has been evolved by this terrible discipline without. What is that life learning as its vehicles are plunged into strife, into blood-shed, into mutilation, into death? It is learning lessons that without that stern experience it could not learn, without which its evolution would be checked and be unable to proceed it is learning that there is something greater than the body, something greater than the physical existence, something higher, more noble, more compelling, than the guarding of the physical vehicle from injury and even from death; and the poorest soldier who goes out on a campaign, who goes through hardship after hardship, who finds himself frozen with cold or burnt up with heat, who plunges through frozen river or toils across sandy desert, who learns to preserve discipline and submission under hardship, who learns to keep cheerful under difficulty, so that his comrades may not be depressed, who is moved, not by the thought of the body which is suffering, but by the great ideal of the military renown of his regiment, and the safety of the country which he is serving, who is learning thus to sacrifice himself for an ideal, is developing thereby qualities invaluable in lives to come. Need I say this to you, who know the place of the Kshattriya in human evolution? Did Manu when he described these different castes demarcate a caste that had not its place in the evolution of life, that had not something to teach? Was not a man kept in the Kshattriya vehicle until he had learned that life was not dependent on the body, that life was to be held at the service of the ideal, at the service of the mother-land that gave him birth, of the king who ruled him, and who to him stood, as to every Hindu the king should stand, as an Avatâra of God? He learned that when that king called him to the battle-field, he had to give his body to mutilation and to death, because the life that was in him recognised the service of the ideal as evolving the real life, and the body as a mere garment to be thrown aside when duty called? Without that training, no Brâhmana could be; no man could come into the caste of the Brâhmana, save as he had gone through that discipline in the ranks of the Kshattriya; because until he had learned that life was everything and form nothing--and that is the lesson which war teaches when it is rightly understood--until that lesson was learned, he was not prepared for the far harder evolution of the life, which is to master the lesson of unity beneath diversity, of love beneath antagonism, of being the friend of every creature and the foe of none.
