Now, you see that the result of this teaching is that all the duties of the world are sanctified. There is no duty in this world which we have any right to call menial: and each man's work is quite as good as that of the emperor on his throne.
Listen to Buddha's message — a tremendous message. It has a place in our heart. Says Buddha, "Root out selfishness, and everything that makes you selfish. Have neither wife, child, nor family. Be not of the world; become perfectly unselfish." A worldly man thinks he will be unselfish, but when he looks at the face of his wife it makes him selfish. The mother thinks she will be perfectly unselfish, but she looks at her baby, and immediately selfishness comes. So with everything in this world. As soon as selfish desires arise, as soon as some selfish pursuit is followed, immediately the whole man, the real man, is gone: he is like a brute, he is a slave' he forgets his fellow men. No more does he say, "You first and I afterwards," but it is "I first and let everyone else look out for himself."
