The Kerala stared at him intently, and Ismail gulped, feeling the heat of that impatient eye. The Kerala was short and compact, black haired, narrow faced, quick of movement. His torso seemed just a touch too long for his legs. His face was very handsome, chiselled like a Greek statue.

'I hope you are impressed by the hospital here,' he said in clear Persian.

'It is the best I have ever seen.'

'What was the state of Ottoman medicine when you left it?'

Ismail said, 'We were making progress in understanding a little of the parts of the body. But much remained mysterious.'

Bhakta added, 'Ismail has examined the medical theories of the ancient Egyptians and Greeks, and brought what was useful in them to us, as well as making very many new discoveries of his own, correcting the ancients or adding to their knowledge. His letters to us have formed one of the main bases of our work in the hospital.'

'Indeed.' Now the Kerala's gaze was even more piercing. His eyes were protuberant, their irises a jumble of colours, like circles of jasper. 'Interesting! We must speak more of these things. But first I want to discuss recent developments with you alone, Mother Bodhisattva.'

The abbess nodded, and walked hand in hand with the Kerala to a pavilion overlooking the dwarf orchard. No bodyguard accompanied them, but only settled back and watched from the yard, rifles at the ready, with guards posted on the monastery wall.

Ismail went with some monks to the streamside, where they were arranging a ceremony of sand mandalas. Monks and nuns in maroon and saffron robes flowed everywhere about the bankside, setting out rugs and flower baskets, happily chattering and in no great hurry, as the Kerala often conferred with their abbess for half the day, or longer. They were famous friends.

Today, however, they finished earlier, and the pace quickened considerably as word came back that the two were leaving the pavilion. Flower baskets were cast on the stream, and the soldiers reappeared to the sound of the pulse quickening tablas. They skipped to the banksides without their rifles and sat, cleaving an aisle for their leader's approach. He came among them, stopping to put a hand to one shoulder or another, greeting men by name, asking after their wounds, and so on. The monks who had led the mandala effort came out of their studio, chanting to a gong and the blast of bass trumpets, carrying two mandalas – wooden discs as big as millstones, each held level by two men, with the vibrantly coloured mandalas laid in unfixed sand on their tops. One was a complex geometrical figure in bold red, green, yellow, blue, white and black. The other was a map of the world, with Travancore a red dot like a bindi, and India occupying the centre of the circle, and the rest of the mandala depicting almost the whole width of the world, from Firanja to Korea and Japan, with Africa and the Indies curved around the bottom. All was coloured naturally, the oceans dark blue, inland seas lighter blue, land green or brown, as the case might be, with the mountain ranges marked by dark green and snowy white. Rivers ran in blue threads, and a vivid red line enclosed what Ismail took to be the border of the Kerala's conquests, now including the Ottoman empire up through Anatolia and Konstantiniyye, though not the Balkans or the Crimea. A most beautiful object, like looking down on the world from the vantage of the sun.

The Kerala of Travancore walked with the abbess, helping her with her footing down the path. At the riverside they stopped, and the Kerala inspected the mandalas closely, slowly, pointing and asking the abbess and ber monks questions about one feature or another. Other monks chanted in low voices, and the soldiers helped to sing a song. Bhakta faced them and sang over their sound in a high thin voice. The Kerala took the mandala in his hands and lifted it up carefully; it was almost too large for one man to hold. He stepped down into the river with it, and bouquets of hydrangea and azalea floated into his legs. He held the geometrical mandala over his head, offering it to the sky, and then, at a shift in the song, and the growling entry of trumpets, he lowered the disc in front of him, and very slowly tilted it up on its side. The sand slid off all at once, the colours pouring into the water and blurring together, staining the Kerala's silken leggings. He dipped the disc into the water and washed the rest of the sand away in a multi coloured cloud that dissipated in the flow. He cleared the surface with his bare hand, then strode out of the water. His shoes were muddy, his wet leggings stained green and red and blue and yellow. He took the other mandala from its makers, bowed over it to them, turned and took it into the river. This time the soldiers shifted and bowed forehead to ground, chanting a prayer together. The Kerala lowered the disc slowly, and like a god offering a world to a higher god, rested it on the water and let it float, spinning slowly round and round under his fingers, a floating world that at the height of the song he plunged down into the stream as far as it would go, releasing all the sand into the water to float up over his arms and legs. As he walked to shore, spangled with colour, his soldiers stood and shouted three times, then three again.

Later, over tea scented with delicate perfumes, the Kerala sat in repose and spoke with Ismail. He heard all Ismail could tell him of Sultan Selim the Third, and then he told Ismail the history of Travancore, his eyes never leaving Ismail's face.

'Our struggle to throw off the yoke of the Mughals began long ago with Shivaji, who called himself Lord of the Universe, and invented modern warfare. Shivaji used every method possible to free India. Once he called the aid of a giant Deccan lizard to help him climb the cliffs guarding the Fortress of the Lion. Another time he was surrounded by the Bijapuri army, commanded by the great Mughal general Afzal Khan, and after a siege Shivaji offered to surrender to Afzal Khan in person, and appeared before that man clad only in a cloth shirt, that nevertheless concealed a scorpion tail dagger; and the fingers of his hidden left hand were sheathed in razor edged tiger claws. When he embraced Afzal Khan he slashed him to death before all, and on that signal his army set on the Mughals and defeated them.

'After that Alamgir attacked in earnest, and spent the last quarter century of his life reconquering the Deccan, at a cost of a hundred thousand lives per year. By the time he subdued the Deccan his empire was hollowed. Meanwhile there were other revolts against the Mughals to the northwest, among Sikhs, Afghans and the Safavid empire's eastern subjects, as well as Rajputs, Bengalis, Tamils and so forth, all over India. They all had some success, and the Mughals, who had overtaxed for years, suffered a revolt of their own zamindars, and a general breakdown of their finances. Once Marathas and Rajputs and Sikhs were successfully established, they all instituted tax systems of their own, you see, and the Mughals got no more money from them, even if they still swore allegiance to Delhi.

'So things went poorly for the Mughals, especially here in the south. But even though the Marathas and Rajputs were both Hindu, they spoke different languages, and hardly knew each other, so they developed as rivals, and this lengthened the Mughals' hold on mother India. In these end days the Nazim became premier to a khan completely lost to his harem and hookah, and this Nazim went south to form the principality that inspired our development of Travancore on a similar system.

'Then Nadir Shah crossed the Indus at the same ford used by Alexander the Great, and sacked Delhi, slaughtering thirty thousand and taking home a billion rupees of gold and jewels, and the Peacock Throne. With that the Mughals were finished.

'Marathas have been expanding their territory ever since, all the way into Bengal. But the Afghans freed themselves from the Safavids, and surged east all the way to Delhi, which they sacked also. When they withdrew the Sikhs were given control of the Punjab, for a tax of onefifth of the harvests. After that the Pathans sacked Delhi yet once more, rampaging for an entire month in a city become nightmare. The last emperor with a Mughal title was blinded by a minor Afghan chieftain.
