And eight thousand Rakshasas called Kinkaras, fierce, huge-bodied and endued with great strength, of red coppery eyes and arrowy ears, well-armed and capable of ranging through the air, used to guard and protect that palace. Within that palace Maya placed a peerless tank, and in that tank were lotuses with leaves of dark-coloured gems and stalks of bright jewels, and other flowers also of golden leaves. And aquatic fowls of various species sported on its bosom. Itself variegated with full-blown lotuses and stocked with fishes and tortoises of golden hue, its bottom was without mud and its water transparent. There was a flight of crystal stairs leading from the banks to the edge of the water. The gentle breezes that swept along its bosom softly shook the flowers that studded it. The banks of that tank were overlaid with slabs of costly marble set with pearls. And beholding that tank thus adorned all around with jewels and precious stones, many kings that came there mistook it for land and fell into it with eyes open. Many tall trees of various kinds were planted all around the palace. Of green foliage and cool shade, and ever blossoming, they were all very charming to behold. Artificial woods were laid around, always emitting a delicious fragrance. And there were many tanks also that were adorned with swans and Karandavas and Chakravakas (Brahminy ducks) in the grounds lying about the mansion.
