The great battle that the Sufis and sages and Yogis fight is the battle with the ego, but the sage battles with his own ego, the ordinary man with other people's egos. And the difference in the result of these two battles is that the victory and the failure of the ordinary man are momentary, but the victory of the sage is eternal. The former, when they have finished one battle, must begin another, but the latter, once he has succeeded, is victorious. All that the former gains, after all, is not his own, because his kingdom is not his own; all he gains does not belong to him, but the sage is king in his own kingdom.
