The Tasks and Aims of Spiritual Science

If one thinks in this way, then all the dangers which are otherwise bound up with what is called the Theosophical Movement, will be, in the main, averted. These very dangers will however immediately arise if people develop clairvoyant powers and do not see to it that their thinking, and more especially their perception and discernment, are enriched at the same time through their own thinking. Many people have the desire just to seize hold of something out of the spiritual world instead of carefully bringing their perceptive thought to bear upon what has after all to be acquired on the physical plane. Even a God cannot comprehend the world in terms of thought unless he incarnates on this physical earth. He can comprehend the world in other forms and ways, but to comprehend it in this form he must incarnate upon the earth. If you reflect upon this it will be clear to you that there are certain dangers connected with the development of faculties within oneself which are then wrongly used. He who develops a certain visionary clairvoyance and uses it wrongly by cutting off all possibility of convincing the world with it, he who remains on the astral plane alone and does not bring his experiences down on to the physical plane, is laying himself open to the danger that an abyss will open between his visions and the physical plane. Let us suppose that someone has had visions of real significance which belong to the astral plane. They may be true visions of reality—for this may happen even with the non-thinking, visionary clairvoyant. But now between him and the real foundations of the physical plane there opens out an abyss. Imagine for a moment that this cloth were the physical plane. The visionary clairvoyant is standing in front of it; he sees his vision. But behind the physical plane is the real spiritual world; the physical plane is Maya. The visionary clairvoyant does not strip away the physical plane; this can be done only by one who makes use of the means of thought. Then only do you penetrate behind the physical plane; only with thinking clairvoyance can you ever understand it. The physical plane is there, but you do not see the spiritual world, the real spiritual world. The abyss opens before you, and the physical plane remains as Maya. And the impossibility of penetrating through the physical plane rests upon the fact that the brain is not capable of eliminating itself. If you have learnt to think rightly, you do not directly use your brain in thinking. Thinking works on the brain, but the activity of thinking does not directly need the brain; it is nonsense to assert that the brain itself thinks.
