I. The Astral Centers
If one reflects upon such matters, one can measure how deep a source of illusion and fantasy they supply. It is this that he who desires to foster the ten-petalled lotus must dam up, for by means of the latter one can perceive characteristics deeply embedded in human and other beings. But the truth can only be extracted from these perceptions if one has entirely freed oneself from the delusions here described. For this purpose it is necessary that one should become master of that which is carried in to one from the external world. One must extend this mastery so far that veritably one does not receive those influences which one does not desire to receive, and this can only be achieved gradually by living a very powerful inward life. This must be so thoroughly done that one only allows those things to impress one on which one voluntarily directs the attention, and that one really prevents those impressions which might otherwise be unconsciously registered. What is seen must be voluntarily seen, and that to which no attention is given must actually no longer exist for oneself. The more vitally and energetically the soul does its inward work, the more will it acquire this power. The occult student must avoid all vague wanderings of sight or hearing. For him only those things to which he turns his eye or his ear must exist. He must practise the power of hearing nothing even in the loudest disturbance when he wishes to hear nothing: he must render his eyes unimpressionable to things which he does not especially desire to notice. He must be shielded as by a mental armor from all unconscious impressions. But in the region of his thoughts particularly must he apply himself in this respect. He puts a thought before him and only seeks to think such thoughts as, in full consciousness and freedom, he can relate to it. Fancy he rejects. If he finds himself anxious to connect one thought with another, he feels round carefully to discover how this latter thought occurred to him. He goes yet further. If, for instance, he has a particular antipathy for anything, he will wrestle with it and endeavor to find out some conscious connection between the antipathy and its object. In this way the unconscious elements in his soul become ever fewer and fewer. Only by such severe self-searching can the ten-petalled lotus attain the form which it ought to possess. The mental life of the occult student must be an attentive life, and he must know how to ignore completely everything which he does not wish, or ought not, to observe.
