Percepção supra-sensorial (um trecho em Inglês do livro 'Fundamentals of Therapy' de Ita Wegman e Rudolf Steiner)

“All the results of the accepted science of our time are derived from the impressions of the human senses. For to whatever degree, in experiment or in observation with the help of instruments, man may extend the sphere of what is yielded by his senses, nothing in essence new is added by these means to his experience of that world in which the senses place him.
But his thinking too, inasmuch as he applies it in his researches of the physical world, adds nothing new to what is given through the senses. In thinking he associates, analyses the sense-impressions, and so forth, in order to reach the laws (the Laws of Nature); yet the man who researches into this world must say to himself: “This thinking, as it wells up within me, adds nothing real to what is already real in the world of sense.”
Now all this at once becomes different if we no longer stop short at the thinking activity which is yielded, to begin with, by ordinary life and education. This thinking can be strengthened, vitalised within itself. We place some simple, easily encompassed thought in the centre of consciousness and, to the exclusion of all other thoughts, concentrate all the power of the soul on the one conception. Then, as a muscle grows strong when exerted again and again in the direction of the same force, our force of soul grows strong when exercised in this way with respect to that sphere of existence which otherwise holds sway in Thought. It should again be emphasised that these exercises must be based on simple, easily encompassed thoughts. For in carrying out the exercises the soul must not be exposed to any kind of influences from the unconscious or the semi-conscious. (Here we can but indicate the principle; a fuller description, and directions showing how such exercises should be done in individual cases, will be found in Rudolf Steiner’s books, Knowledge of the Higher Worlds and its Attainment, An Outline of Occult Science, and other works in Anthroposophy.)
Anthroposophy shows how the exercises should be done from the outset; it shows the way to advance within the sphere of consciousness, step by step and fully wide-awake in carrying out the exercises, as in the solving of an arithmetical or geometrical problem. At no point in solving a problem of Arithmetic or Geometry can our consciousness slide into unconscious regions; nor can it do so during the practices here indicated, provided always that the anthroposophical directions are properly observed. In the course of such training we attain a strengthening of the force of thought of which we had not the remotest idea before. Like a new content of our human being we feel the force of thought holding sway within us. And with this new content of our own human being, there is revealed at the same time a World-content which, though we might perhaps have divined its existence, was unknown to us by experience until now.
If in a moment’s introspection we consider our everyday activity of thought, we find that the thoughts are shadow-like beside the impressions that out senses give us. What we perceive in the now strengthened force of thought is not pale or shadow-like by any means. It is full of inner content, vividly real and graphic; it is, indeed of a reality far more intense than the contents of our sense-impressions.
A new world begins to dawn for the man who has thus enhanced the force of his perceptive faculty. He, who till now was only able to perceive in the world of the senses, learns to perceive in this new world.”
