He was torn by the struggle for an interminable instant, and then it was over. He felt it writhe loose from the encumbrance of his mind, like a madman writhing out of a strait-jacket, and then It was falling back toward Earth, away from him. He could sense It plainly, once It was outside him--a malevolent, intangible Thing that fell back swiftly toward the emerald crescent of Earth. He sat for a moment dazed while breath came back into his lungs and the steel-panelled cubicle grew steady again before his starting eyes. And, when It had gone in the distance and he could no longer feel the frenzy of Its terror, he felt the swift unbounded freedom that a spirited horse feels when it has, unexpectedly, lost its rider. He was still Robert Maynard, but with a difference. _He was free._ * * * * * The feeling of utter freedom staggered him. For the first time in his life he possessed himself entirely, without doubt or reservation, a complete and serene entity. He could feel his consciousness still expanding, reaching into every hidden corner of his mind and taking control of functions he had not dreamed of before. An analogy occurred to him in perfect exactness of detail: he was like a man waking from a vague world of sleep to find that what he had thought a single small room was in reality a spacious house. There were other rooms than the cramped chamber he had lived in all his life--rooms that had been tenanted a moment before by Something else, but which lay open and ready for his own use now that their Tenant was gone. A moment before his ego had occupied a meager one-twelfth of his brain; with Its departure the whole of his mind was his. As suddenly as that he knew what had happened to him and why, and his incredibly-multiplied intelligence arranged the details of it precisely for his consideration. He had been host to a parasitic intelligence, without knowing it, all his life. He had moved at Its dictates, following his own will only when It slept or tired or was distracted, never succeeding fully in any endeavor of his own because It was in control and must be obeyed. He knew when he had explored the vacated premises of his newly freed mind that It was only one of many, that all earthmen had Tenants like It, intangible parasitic entities subsisting upon and controlling the human life force. He thought: _No wonder we have wars on Earth! We have no common ground for agreement because we are under Their compulsion. They know our inherent abilities and keep us at each others' throats lest we learn of and destroy them. Everything that man has accomplished has been done in spite of Them._
