At once the motion made and thoughts aroused elicit their own sound, color, motion in ether, amount of etheric light, symbolic picture, disturbance of elemental forces, and so on through the great catalogue. Did but one wink his eye, the same effects follow in due order. Nothing, absolutely nothing. Stop all attempts at clairvoyance. Because it leads them slowly but surely - almost beyond recall into an interior and exterior passive state where the will is gradually overpowered and they are at last in the power of the demons who lurk around the threshold of our consciousness.
Madness lies that way.
But they are not. They are caused by the ethereal fluids from within us making their way out through the skin and thus producing the illusion of a touch. Study the philosophy of life, leave the decorations that line the road of spiritual development for future lives, and practice altruism.
