People will do anything, no matter how absurd, in order to avoid facing their own souls. They will practice Indian yoga and all its exercises, observe a strict regimen of diet, learn theosophy by heart, or mechanically repeat mystic text from the literature of the whole world – all because they cannot get on with themselves and have not slightest faith that anything useful could ever come out of their own souls. Thus the soul has been turned into a Nazareth Gradually from which nothing good can come. Therefore let us fetch it from the four corners of the earth – the more far-fetched and bizarre it is the better. ~ Carl Jung, CW 13, Page 99.

If one studies the occult with the wrong attitude one can get infected, for this whole field is full of metaphysical traps through which one can fall, disappear as into an oubliette, and became the astrologer, the theosophist, or the black magician. ~Carl Jung, Visions Seminar,  Page 72

If we now try to cover our nakedness with the gorgeous trappings of the East, as the theosophists do, we would be playing our own history false. A man does not sink down to beggary only to pose afterwards as an Indian potentate. It seems to me that it would be far better stoutly to avow our spiritual poverty, our symbol-lessness, instead of feigning a legacy to which we are not the legitimate heirs at all. We are, surely, the rightful heirs of Christian symbolism, but somehow we have squandered this heritage. We have let the house our fathers built fall into decay, and now we try to break into Oriental palaces that our fathers never knew. ~Carl Jung, CW 9i, Para 28

The usual mistake of Western man when faced with this problem of grasping the ideas of the East is like that of the student in Faust. Misled by the devil, he contemptuously turns his back on science and, carried away by Eastern occultism, takes over yoga practices word for word and becomes a pitiable imitator. (Theosophy is our best example of this.) ~~Carl Jung, CW 11, Para 3

I don’t say that we should accept an Eastern philosophy. Many people do go in for Indian theosophy and such stuff, but I am an opponent of that because I know that for us it is not healthy. ~Carl Jung, Dream Analysis Seminar, Page 622.

Filling the conscious mind with ideal conceptions is a characteristic of Western theosophy, but not the confrontation with the shadow and the world of darkness. One does not become enlightened by imagining figures of light, but by making the darkness conscious. ~Carl Jung, CW 13, Page 335

Though it would be wrong to draw a parallel between Darmstadt and theosophy, it does seem to me that the same danger exists in both cases: of a new house being built on the old shaky foundations, and of new wine being poured into old bottles. Though the old damage is covered up, the new building does not stand firm. Man must after all be changed from within, otherwise he merely assimilates the new material to the old pattern. ~Carl Jung, Letters Vol. 1, Page 40

You are quite right in supposing that I reckon astrology among those movements which, like theosophy, etc., seek to assuage an irrational thirst for knowledge but actually lead it into a sidetrack. Astrology is knocking at the gates of our universities: a Tubingen professor has switched over to astrology and a course on astrology was given at Cardiff University last year.  Astrology is not mere superstition but contains some psychological facts (like theosophy) which are of considerable importance. Astrology has actually nothing to do with the stars but is the 5000-year-old psychology of antiquity and the Middle Ages. Unfortunately I cannot explain or prove this to you in a letter. ~Carl Jung, Letters Vol. 1, Page 56

Sometimes you express yourself ( in the MS ) as if my symbols and my text were a sort of confession or a belief. Thus it looks as if I were moving in the vicinity of theosophy. In America especially one blames me for my so-called mysticism. Since I don’t claim at all to be the happy proprietor of metaphysical truths, I should much prefer that you attribute to my symbols the same tentativeness which characterizes your explanatory attempt. ~Carl Jung, Letters Vol. 1, Page 290

I don’t feel happy about these things, since you merely fall into such experiences without being able to integrate them. The result is a sort of theosophy, but it is not a moral and mental acquisition . It is the eternally primitive man having experience of his ghost-land, but it is not an achievement of your cultural development.  ~Carl Jung, Letters Vol. 1, Page 382.
