Evidently there is one difficulty: in your conscious being something does not want the difficulty, wishes sincerely to overcome it, but there are numberless movements in other parts of your consciousness of which you are not conscious. You say, “I want to be cured of that”; unfortunately it is not sufficient to say “I want”, there are other parts of the consciousness which hide themselves so that you may not be busy with them, and when your attention is turned away these parts try to assert themselves. That is why I say and shall always repeat, Be perfectly sincere; do not try to deceive yourself, do not say, “I have done all that I could.” If you do not succeed, it means that you do not do all that you can. For, if you truly do “all” that you can, you will surely succeed. If you have any defect which you want to get rid of and which still persists, and you say, “I have done all that I could”, you may be sure that you have not done all that you should have. If you had, you would have triumphed, for the difficulties that come to you are exactly in proportion to your strength—nothing can happen to you which does not belong to your consciousness, and all that belongs to your consciousness you are able to master. Even the things and suggestions that come from outside can touch you only in proportion to the consent of your consciousness, and you are made to be the master of your consciousness. If you say, “I have done all that I could and in spite of everything the thing continues, so I give up”, you may be already sure that you have not done what you could. When an error persists “in spite of everything” it means that something hidden in your being springs up suddenly like a Jack-in-the-box and takes the helm of your life. Hence, there is only one thing to do, it is to go hunting for all the little dark corners which lie hidden in you and, if you put just a tiny spark of goodwill on this darkness, it will yield, will vanish, and what appeared to you impossible will become not only possible, practicable, but it will have been done. You can in this way in one minute get rid of a difficulty which would have harassed you for years. I absolutely assure you of it. That depends only on one thing: that you truly, sincerely, want to get rid of it.
