If you identify with the distinguished ﬁgure, all the minor qualities have no place in that image, but are excluded, and they will heap up and cover the fountain of life, which is of course the unconscious.
Out of the unconscious ﬂows the well of life, and what you don’t accept in yourself naturally falls back into that well and poisons it; when you don’t recognize certain facts, they form a layer in the unconscious through which the water of life must come up, and it will be poisoned by all those things you have left down below.
If they are accepted in your conscious life, then they are mixed with other more valuable and cleaner sub- stances, and the odious qualities of the lower functions disappear more or less.
They only form little shadows here and there, sort of spice for the good things.
But by excluding them, you cause them to heap up and they become entirely evil substances; for a thing to become poisonous, you only need to repress it.
If you carefully sterilize everything that you do, you make an extract of the impurity and leave it at the bot- tom, and once the water of life is poisoned, it doesn’t need much to make everything wrong. Carl Jung, Zarathustra Seminar, Page 1058.
