Our various Yogas do not conflict with each other; each of them leads us to the same goal and makes us perfect. Only each has to be strenuously practiced. The whole secret is in practicing. First you have to hear, then think, and then practice. This is true of every Yoga. You have first to hear about it and understand what it is; and many things which you do not understand will be made clear to you by constant hearing and thinking. It is hard to understand everything at once. The explanation of everything is after all in yourself. No one was ever really taught by another; each of us has to teach himself. The external teacher offers only the suggestion which rouses the internal teacher to work to understand things. Then things will be made clearer to us by our own power of perception and thought, and we shall realise them in our own souls; and that realisation will grow into the intense power of will. First it is feeling, then it becomes willing, and out of that willing comes the tremendous force for work that will go through every vein and nerve and muscle, until the whole mass of your body is changed into an instrument of the unselfish Yoga of work, and the desired result of perfect self-abnegation and utter unselfishness is duly attained. This attainment does not depend on any dogma, or doctrine, or belief. Whether one is Christian, or Jew, or Gentile, it does not matter.
