4.20

"At that time, Crown Prince Kalyāṇamitra and the blind guide proceeded forward on the road. Traveling for seven days, the water came up to their knees. Advancing for another seven days, the water came up to their necks. Advancing for another seven days, they swam and were able to cross. They then reached a place in the sea whose ground was entirely of white silver sand. The guide asked: 'What is this ground?' The prince replied: 'The ground is entirely white silver sand.' The guide said: 'Looking around in all four directions, there should be a white silver mountain. Have you seen it yet?' The prince said: 'In the southeast, a white silver mountain appears.' The guide said: 'This path lies below that mountain.' Having arrived at that mountain, the guide said: 'Next we should reach golden sand.'
