You know just a little and you begin to teach others, and you are immediately compelled to say more than you know, because people put questions to you which you cannot answer, unless you are a hero of silence. In the world, those who want to pass themselves off as spiritual teachers—when people come and ask them something they do not know, they invent it. Therefore, if in your inner discipline you begin to pretend, you may be sure of falling into the worst hole—of all things pretence is the most ruinous. In the world you may perhaps pass for what you are not, for people allow themselves to be easily deceived, and that will not lead you to a catastrophe (although if you exaggerate, it always leads to a catastrophe), but in the spiritual world, you don’t have to deal with human beings, you have to deal with the Divine; it is impossible for you to pretend that you are this or that, for the Divine knows better than you, doesn’t He? He knows what you are and it is not what you will say which will influence Him.
