Surely this red one was the devil, but my devil. That is, he was my joy, the joy of the serious person, who keeps watch alone on the high tower-his red-colored, red-scented, warm bright red joy. Not the secret joy in his thoughts and in his looking, but that strange joy of the world that comes unsuspected like a warm southerly wind with swelling fragrant blossoms and the ease of living. You know it from your poets, this seriousness, when they expectantly look toward what happens in the depths, sought out first of all by the devil because of their spring-like joy. It picks up men like a wave and drives them forth. Whoever tastes this joy forgets himself And there is nothing sweeter than forgetting oneself And not a few have forgotten what they are. But even more have taken root so firmly that not even the rosy wave is able to uproot them. They are petrified and too heavy, while the others are too light.
I earnestly confronted my devil and behaved with him as with a real person. This I learned in the Mysterium: to take seriously every unknown wanderer who personally inhabits the inner world, since they are real because they are effectual. It does not help that we say in the spirit of this time: there is no devil. There was one with me. This took place in me. I did with him what I could. I could speak with him. A religious conversation is inevitable with the devil, since he demands it, if one does not want to surrender to him unconditionally. Because religion is precisely what the devil and I cannot agree about. I must have it out with him, as I cannot expect that he as an independent personality would accept my standpoint without further ado. I would be fleeing if I did not try to come to an understanding with him. If ever you have the rare opportunity to speak with the devil, then do not forget to confront him in all seriousness. He is your devil after all. The devil as the adversary is your own other standpoint; he tempts you and sets a stone in your path where you least want it.
Taking the devil seriously does not mean going over to his side, or else one becomes the devil. Rather it means coming to an understanding. Thereby you accept your other standpoint. With that the devil fundamentally loses ground, and so do you. And that may be well and good.
Although the devil very much abhors religion for its particular solemnity and candor, it has become apparent, however, that it is precisely through religion that the devil can be brought to an understanding. What I said about dancing struck him because I spoke about something that belonged in his own domain. He fails to take seriously only what concerns others because that is the peculiarity of all devils. In such a manner, I arrive at his seriousness, and with this we reach common / ground where understanding is possible. The devil is convinced that dancing is neither lust nor madness, but an expression of joy, which is something proper to neither one nor the other. In this I agree with the devil. Therefore he humanizes himself before my eyes. But I turn green like a tree in spring. ~Carl Jung; Red Book.
