"Where did you get this idea? Is it in the Koran?"

"Actually, it is a concept that appears in one way or another in most of the great religions. I have changed it slightly to suit what we have learned about the world in the last few hundred years. But the Holy Koran gives me my inspiration for this kind of study, because the Koran commands me to study everything, and learn everything, in order to serve Allah."

"But where does this _life _characteristic come from?" I insisted, sure that I had him trapped in a reductionist dead-end at last.

"Life, and all the other characteristics of all the things in the universe, such as consciousness, and free will, and the tendency toward complexity, and even love, was given to the universe by light, at the beginning of time as we know it."

"At the Big Bang? Is that what you're talking about?"

"Yes. The Big Bang expansion happened from a point called a singularity-another of my favourite five-syllable English words - that is almost infinitely dense, and almost infinitely hot, and yet it occupies no space and no time, as we know those things.

The point is a boiling cauldron of light energy. Something caused it to expand-we don't know yet what caused it-and from light, all the particles and all the atoms came to exist, along with space and time and all the forces that we know. So, light gave every little particle at the beginning of the universe a set of characteristics, and as those particles combine in more complex ways, the characteristics show themselves in more and more complex ways."

He paused, watching my face as I struggled with the concepts and questions and emotions that looped in my mind. He got away from me again, I thought, suddenly furious with him for having an answer to my question, and yet struck with admiring respect for the same reason. There was always something eerily incongruous in the wise lectures-sometimes they were like sermons-of the mafia don Abdel Khader Khan. Sitting there against a stone wall in an all-but-Stone Age village in Afghanistan, with a cargo of smuggled guns and antibiotics nearby, the dissonance created by his calm, profound discourse about good and evil, and light and life and consciousness, was enough to fill me with exasperated irritation. "What I have just told you is the relationship between consciousness and matter," Khader proclaimed, pausing again until he had my eye. "This is a kind of test, and now you know it. This is a test that you should apply to every man who tells you that he knows the meaning of life. Every guru you meet and every teacher, every prophet and every philosopher, should answer these two questions for you: What is an objective, universally acceptable definition of good and evil? And, What is the relationship between consciousness and matter? If he cannot answer these two questions, as I have done, you know that he has not passed the test."

"How do you know all this physics?" I demanded. "All this about particles and singularities and Big Bangs?"

He stared at me, reading the full measure of the unconscious insult: How is it that an Afghan gangster like you knows so much about science and higher knowledge? I looked back at him, remembering a day at the slum with Johnny Cigar when I'd made the cruel mistake of assuming him to be ignorant simply because he was poor.

"There is a saying-When the student is ready, the teacher appears-do you know it?" he asked, laughing. It seemed that he was laughing at me, rather than with me.

"Yes," I whistled patiently, through clenched teeth.

"Well, just at the point in my studies of philosophy and religion when I came to need the special knowledge of a scientist, one appeared for me. I knew that there were many answers for me in the science of life and stars and chemistry. But, unfortunately, these were not the things that my dear Mackenzie Esquire taught to me, except in the most elementary fashion. Then I met a physicist, a man who was working at the Bhabha Atomic Research Centre in Bombay. He was a very good man, but he had a weakness for gambling at that time. He found himself in big trouble. He lost a lot of money that was not his to lose. He was gambling at one of the clubs owned by a man I knew well-a man who worked for me, if I needed it. And there was more trouble. The scientist was involved with a woman-he fell in love with her, and he did stupid things for the sake of this love, and so there were many dangers. When he came to me, I solved the problems of this scientist, and kept all the matters strictly between us. No-one else ever knew the details of his indiscretions, or of my involvement in solving them. And, in exchange for this, the man has been teaching me ever since that day. His name is Wolfgang Persis, and I have arranged it that you will meet him, if you wish, soon after we return."

"How long has he been teaching you?"

"We have been studying together once every week for the past seven years."

"Jesus!" I gasped, thinking, with a little curl of mean delight, that wise and mighty Khader hacked out his pound of flesh when it suited him. In another heartbeat I was ashamed of the thought: I loved Khader Khan enough to follow him into a war. Wasn't it possible that the scientist loved him just as well? And in thinking that, I knew I was jealous of the man, the scientist I didn't know and probably would never meet. Jealousy, like the flawed love that bears it, has no respect for time or space or wisely reasoned argument. Jealousy can raise the dead with a single, spiteful taunt, or hate a perfect stranger for nothing more than the sound of his name.

"You are asking about life," Khader said gently, changing tack, "because you are thinking about death. And you are thinking about the taking of a life, if it happens that you must shoot a man. Am I right in this?"

"Yeah," I muttered. He was right, but the killing that preoccupied me wasn't in Afghanistan. The life I wanted to take was perched on a throne, in a secret room in a grotesque brothel called The Palace, in Bombay. Madame Zhou.

"Remember," Khader said insistently, resting his hand on my forearm to emphasise his words. "Sometimes it is necessary to do the wrong thing for the right reasons. The important thing is to be sure that our reasons are right, and that we admit the wrong- that we do not lie to ourselves, and convince ourselves that what we do is right."

And later, as the wedding whirled and clamoured to the last wail of its rejoicing, and as we rejoined our men and scrambled, clattered, and strained our way across new mountains, I tried to unwind the wreath of thorns that Khader had coiled around my heart with his words. The wrong thing for the right reasons...

Once before he'd tormented me with that phrase. I chewed at it, in my mind, as a bear will chew at a leather strap that binds it by the leg. In my life, the wrong things were almost always done for the wrong reasons. Even the right things that I did were too often goaded by the wrong reasons.

A gloomy mood enwrapped me. It was a sullen, doubting temper that I couldn't shake off, and as we rode into the winter I thought often of Anand Rao, my neighbour from the slum. I remembered Anand's face smiling at me through the metal grille of the visitor's room at Arthur Road Prison: that gentle, handsome face, so serene, and softened with the peace that had suffused his heart. He'd done the wrong thing for the right reasons, as he saw it. He'd calmly accepted the punishment that he'd earned, as he said to me, as if it was a privilege or a right. And at last, after too many thinking days and nights, I cursed Anand. I cursed him to drive him from my mind because a voice kept telling me-my own voice, or maybe it was my father's-that I would never know that peace.

I would never come to that Eden in the soul, where acceptance of punishment and acknowledgement of wrong and right roll away the troubles that lodge like stones in the barren field of an exiled heart.
