are far apart. The image, it seemed to Kull, had an individuality apart from Kull's; he was no more dependent on Kull than Kull was dependent on him. And day by day Kull doubted in which world he really lived; was he the shadow, summoned at will by the other? Did he instead of the other live in a world of delusion, the shadow of the real world?
Kull began to wish that he might enter the personality beyond the mirror for a space, to see what might be seen; yet should he manage to go beyond that door could he ever return? Would he find a world identical with the one in which he moved? A world, of which his was but a ghostly reflection? Which was reality and which illusion?
At times Kull halted to wonder how such thoughts and dreams had come to enter his mind and at times he wondered if they came of his own volition or—here his thoughts would become mazed. His meditations were his own; no man ruled his thoughts and he would summon them at his pleasure; yet could he? Were they not as bats, coming and going, not at his pleasure but at the bidding or ruling of—of whom? The gods? The Women who wove the webs of Fate? Kull could come to no conclusion, for at each mental step he became more and more bewildered in a hazy gray fog of illusory assertions and refutations. This much he knew: that strange visions entered his mind, like bats flying unbidden from the whispering void of non-existence; never had he thought these thoughts, but now they ruled his mind, sleeping and waking, so that he seemed to walk in a daze at times; and his sleep was fraught with strange, monstrous dreams.
"Tell me, wizard," he said, sitting before the mirror, eyes fixed intently upon his image, "how can I pass yon door? For of a truth, I am not sure that that is the real world and this the shadow; at least, that which I see must exist in some form."
"See and believe," droned the wizard. "Man must believe to accomplish. Form is shadow, substance is illusion, materiality is dream; man is because he believes he is; what is man but a dream of the gods? Yet man can be that which he wishes to be; form and substance, they are but shadows. The mind, the ego, the essence of the god-dream—that is real, that is immortal. See and believe, if you would accomplish, Kull."
The king did not fully understand; he never fully understood the enigmatical utterances of the wizard, yet they struck somewhere in his being a dim responsive chord. So day after day he sat before the mirrors of Tuzun Thune. Ever the wizard lurked behind him like a shadow.
Then came a day when Kull seemed to catch glimpses of strange lands; there flitted across his consciousness dim thoughts and recognitions. Day by day he had seemed to lose touch with the world; all things had seemed each succeeding day more ghostly and unreal; only the man in the mirror seemed like reality. Now Kull seemed to be close to the doors of some mightier worlds; giant vistas gleamed fleetingly; the fogs of unreality thinned; "form is shadow, substance is illusion; they are but shadows" sounded as if from some far country of his consciousness. He remembered the wizard's words and it seemed to him that now he almost understood—form and substance, could not he change himself at will, if he knew the master key that opened this door? What worlds within what worlds awaited the bold explorer?
