“Excuse me, Mijnheer Swammerdam, I would like to ask you a brief question. All that you said about hysteria and the power that resides in names made me think; but, on the other hand …”“Allow me to give you a piece of advice, Mejuffrouw.” Swammerdam looked at her earnestly. “I am well aware that everything that you saw and heard just now has only confused you. But it could be of great importance to you if you learn from it the first lesson, and that is to seek spiritual enlightenment not from others but within yourself. Only the teachings that come from our own spirit come at the right moment, at the moment when we are ready for them. You must close your eyes and ears to revelations made to others. The path to eternal life is as narrow as a knife-edge; you cannot help others when you see them stumble, nor should you expect help from them. Anyone who watches others will lose his balance and plunge into the abyss. Here we do not advance together as in the world outside; a guide is essential, but he must come to you from the spirit world.
