Osho – Remember this. It is impossible to help others till you have obtained some certainty of your own. Resist the temptation to help others. It is evil unless you have obtained some certainty of your own. Don’t try to be a guru, don’t try to be a helper. because you will disturb; you will create more problems. Remember well that you cannot help. you cannot guide anyone. unless you have got the inner light. When the inner light is there, the help, the guidance, will flow from you.
Resist the temptation. The temptation is great, because the ego feels very fulfilled. Someone comes to ask your advice. The temptation is there to give advice without knowing what you are doing, without being aware that you don’t know. If someone asks you whether God is, you are not strong enough to say, ”I don’t know.” You say something. Either you say, ”Yes. God is. I am a believer,” or you say, ”No, God is not. I am a disbeliever,” but in both.cases you give advice. In both cases you confirm something that you don’t know.
Remember this, for the spiritual seeker a very basic, very significant point: whatsoever you really know, confirm only that. If you don’t know, it is better to say, ”I don’t know.”
