In regard to the world of feeling the soul should attain for spiritual training a certain degree of calmness. It is necessary for that purpose that the soul become ruler over expressions of joy and sorrow, of pleasure and pain. It is just in regard to the acquiring of this ability that much prejudice may result. One might imagine that one would become dull and without sympathy in regard to one’s fellowmen if one should not feel joy with the joyful and with the painful, pain. Yet this is not the point in question. With the joyful the soul should rejoice, with sadness it should feel pain. But it should acquire the ability to control the expression of joy and sorrow, of pleasure and pain. If one endeavors to do this, one will soon notice that one does not become less sensitive, but on the contrary more receptive to all that is joyous and sorrowful in one’s environment than one was previously. To be sure, if one wishes to acquire the ability with which we are concerned here, one must strictly observe oneself for a long period of time. One must see to it that one is able fully to sympathize with joy and sorrow without losing one’s self-control so that one gives way to an involuntary expression of one’s feelings. It is not the justified pain that one should suppress, but involuntary weeping; not the horror of an evil action, but the blind rage of anger; not attention to danger, but fruitless fear, and so forth. — Only through such practice does the student of the spiritual attain the tranquility of mind that is necessary to prevent the soul at the birth of the higher ego, and, above all, during its activity, from leading a second, abnormal life like a sort of Doppelganger — soul double — along side this higher ego. It is just in regard to these things that one should not surrender oneself to any sort of self-deception. It may appear to many a one that he already possesses a certain equanimity in ordinary life and therefore does not need this exercise. It is just such a person who doubly needs it. It may be quite possible to be calm when confronting the things of ordinary life, but when one ascends into a higher world, the lack of equilibrium that heretofore was only suppressed may assert itself all the more. It must be grasped that for spiritual training what one already appeared to possess previously is of less importance than the need to practice, according to exact rules, what one lacks. Although this sentence appears contradictory, it is, nevertheless, correct. Even though life has taught us this or that, the abilities we have acquired by ourselves serve the cause of spiritual training. If life has brought us excitability, we should break ourselves of the habit; if life has brought us complacency, then we should through self-education arouse ourselves to such a degree that the expression of the soul corresponds to the impression received. Anyone who never laughs about anything has just as little control of his life as someone who, without any control whatever, is continually given to laughter.
