Did his nakedness mean anything to her? Among Christians, he knew, men and women often saw each other naked. Not only did women go through the streets with their faces uncovered, but in warm weather the common folk, men and women both, walked to the public baths with barely a bit of cloth wrapped around their loins. And all Christians slept naked. When Sophia saw his body like this, was it just another unclothed body, like the many she had doubtless seen in her lifetime? Did she feel any embarrassment? Or desire? As for himself, his sense of helplessness made him feel only embarrassed, nothing more. He turned his head again to look at her. She was intent on administering the poultice, and that doubtless took her mind off his nakedness. She had lifted off the old cloth, stained an ugly yellow-brown, and dropped it to the floor. He got a glimpse of the wound, a red slit about half a finger's length with black knots of thread in it in the back of his right leg, halfway between knee and buttock. Gently she patted and stroked on the wound a paste made of ground rose petals, lime water, and egg white, the Sufi remedy he had taught her to make. Lorenzo had used his knife to open the hole made by the arrow so that he would not tear Daoud's flesh pulling the barbed head out. While Lorenzo worked over him, Daoud drew upon Saadi's final teaching to him to defend himself against the pain. In his mind he began to create the drug called Soma. He envisioned it as a bowl of glowing, silver-colored liquid, and he believed it could form a capsule around any part of his body where there was pain and wall it off from the rest of himself, at the same time filling him with a feeling of well being. _Once you have experienced the effects of material drugs on your body and learned to master them_, Saadi said to him, _you have the knowledge you need to create a drug of the mind, Soma. This is more powerful and more reliable, and it will not harm your body in any way. Indeed, Soma will make your body stronger. It will calm your mind, fill you with peace, sometimes give you visions. But if you should suddenly need all your faculties, they are yours at once. The drug is gone in an instant._ It was Saadi's teaching that whatever a man could accomplish with drugs, he could accomplish more effectively and reliably with his mind alone. A trained man could envision a drug that would serve any desired purpose. And thus a man could transcend the Hashishiyya reliance on administered drugs. While he had drunk from the bowl of Soma and it had flooded through his body, Daoud's fingers had gripped the little leather case hung around his neck that contained the Sufi tawidh, the numerological invocation that he believed would speed his healing. A river of blood had poured out of his leg when Lorenzo drew out the arrow, and he had fainted. Sophia had stitched the wound with cotton thread that was now black with congealed blood.
