It seems to be very hard for people to live with riddles or to let them live, although one would think that life is so full of riddles as it is that a few more things we cannot answer would make no difference. But perhaps it is just this that is so unendurable, that there are irrational things in our own psyche which upset the conscious mind in its illusory certainties by confronting it with the riddle of its existence. ~Carl Jung, CW 10, Para 307

Often the hands know how to solve a riddle with which the intellect has wrestled in vain. ~Carl Jung, CW 8, Para 180

The nature of the psyche reaches into obscurities far beyond the scope of our understanding. It contains as many riddles as the universe with its galactic systems, before whose majestic configurations only a mind lacking in imagination can fail to admit its own insufficiency. This extreme uncertainty of human comprehension makes the intellectualistic hubbub not only ridiculous, but also deplorably dull. ~Carl Jung, CW 8, Para 815

For behind all this looms the vast and unsolved riddle of life itself and of evolution in general, and the question of overriding importance in the end is not the origin of evolution but its goal. Nevertheless, when a living organism is cut off from its roots, it loses the connections with the foundations of its existence and must necessarily perish. When that happens, anamnesis of the origins is a matter of life and death. ~Carl Jung, CW 9ii, Para 279

The black beetle is the death that is necessary for renewal; and so thereafter, a new sun glowed, the sun of the depths, full of riddles, a sun of the night. And as the rising sun of spring quickens the dead earth, so the sun of the depths quickened the dead, and thus began the terrible struggle between light and darkness. ~Carl Jung, Liber Novus, Page 238.

I went through a torment unto death and I felt certain that I must kill myself if I could not solve the riddle of the murder of the hero. ~Carl Jung, Liber Novus, Page 242.

Just as some alchemists had to admit that they never succeeded in producing the gold or the Stone, I cannot confess to have solved the riddle of the coniunctio mystery. On the contrary I am darkly aware of things lurking in the background of the problem-things too big for our horizons. ~Carl Jung, Letters Vol. II, Page 393.

Together with my wife I have tried to unriddle your words, and we have reached surmises which, for the time being at any rate, I would rather keep to myself. ~Carl Jung, Freud/Jung Letters, Vol. 1, Pages 438-441

For Jung the figure of the detective was a modern version of the alchemical Mercurius, solver of all riddles, and he was entertained by his heroic deeds. He also enjoyed science fiction. ~Aniela Jaffe, Jung’s Last Years, Page 131.

What occurs between the lover and the beloved is the entire fullness of the Godhead. Both are unfathomable riddles to each other. For who understands the Godhead? / But the God is born in solitude, from the secret / mystery of the individual. / The separation between life and love is the contradiction between solitude and togetherness. ~Carl Jung, The Black Books, Feb. 23, 1920, Page 88.
