大方便佛報恩經 4.20

4.20

「爾時善友太子與盲導師即前進路，行一七日，水齊到膝。復更前行一七，水齊到頸。前進一七，浮而得渡。即到海處，其地純以白銀為沙。導師問言：『此地何物？』太子答言：『其地純是白銀沙。』導師言：『四望應當有白銀山。汝見未耶？』太子言：『東南方有一白銀山現。』導師言：『此道在此山下。』至彼山已，導師言：『次應到金沙。』

"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.'
