In the late afternoon, when the stairway was no longer blasted by the full fury of the sun, the Venerable Parakarma began his descent. By nightfall, he would reach the highest of the pilgrim renthouses; and by the following day, he would have returned to the world of men.
The Mahanayake Thero had given neither advice nor discouragement, and if he was grieved by his colleague’s departure, he had shown no sign. He had merely intoned, “All things are impermanent,” clasped his hands, and given his blessing.
The Venerable Parakarma, who had once been Dr. Choam Goldberg, and might be so again, would have had great difficulty in explaining all his motives. “Right action” was easy to say; it was not so easy to discover.
At the Sri Kanda Maha Vihara he had found peace of mind—but that was not enough. With his scientific training, he was no longer content to accept the Order’s ambiguous attitude toward God. Such indifference had come at last to seem worse than outright denial.
If such a thing as a rabbinical gene could exist, Dr. Goldberg possessed it. Like many before him, Goldberg-Parakarma had sought God through mathematics, undiscouraged even by the bombshell that Kurt Gödel, with the discovery of undecidable propositions, had exploded early in the twentieth century. He could not understand how anyone could contemplate the dynamic asymmetry of Euler’s profound yet beautifully simple e + 1 = 0 without wondering if the universe was the creation of some vast intelligence.
Having first made his name with a new cosmological theory that had survived almost ten years before being refuted, Goldberg had been widely acclaimed as another Einstein or N’goya. In an age of ultraspecialization, he had also managed to make notable advances in aero- and hydrodynamics—long regarded as dead subjects, incapable of further surprises.
Then, at the height of his powers, he had experienced a religious conversion not unlike Pascal’s, though without so many morbid undertones. For the next decade, he had been content to lose himself in saffron anonymity, focusing his brilliant mind upon questions of doctrine and philosophy. He did not regret the interlude, and he was not even sure that he had abandoned the Order; one day, perhaps, this great stairway would see him again. But his God-given talents were reasserting themselves. There was massive work to be done, and he needed tools that could not be found on Sri Kanda—or even, for that matter, on Earth itself.
He felt little hostility, now, toward Vannevar Morgan. However inadvertently, the engineer had ignited the spark; in his blundering way, he, too, was an agent of God. Yet, at all costs, the temple must be protected. Whether or not the wheel of fate ever returned him to its tranquillity, Parakarma was implacably resolved upon that.
And so, like a new Moses bringing down from the mountain laws that would change the destinies of men, the Venerable Parakarma descended to the world he had once renounced. He was blind to the beauties of land and sky that were all around him. They were utterly trivial compared to those that he alone could see in the armies of equations that were marching through his mind.
