In any case the Sufis here proved to be very enthusiastic about the idea of an underground congress. As they pointed out, theirs was a syncretic religion, which had taken some of its elements not only from the various types and nationalities of Islam, but also from the older religions of Asia that Islam had encountered, and also newer ones such as Baha’i. Something similarly flexible was going to be needed here, they said. Meanwhile, their concept of the gift had already been influential throughout the underground, and some of their theoreticians were working with Vlad and Marina on the specifics of eco-economics. So as the morning passed and they waited for the late winter sunrise, standing at the great window and looking across the dark canyon to the east, they were quick to make very practical suggestions about the meeting. “You should go talk to the Bedouin and the other Arabs as quickly as possible,” Dhu told them. “They won’t like being late in the list of those consulted.”

Then the eastern sky lightened, very slowly, from dark plum to lavender. The opposite cliff was lower than the one they were on, and they could see over the dark plateau to the east for a few kilometers, to a low range of hills that formed the horizon. The Sufis pointed out the cleft in the hills where the sun would rise, and some began to chant again. “There is a group of Sufis in Elysium,” Dhu told them, “who are exploring backwards to our roots in Mithraism and Zoroastrianism. Some say there are Mithraists on Mars now, worshipping the sun, Ahura Mazda. They consider the soletta to be religious art, like a stained glass window in a cathedral.”
