阿彌陀經通贊疏 2.45

2.45

贊曰：第四地布黃金。心無穢種，地感黃金，柔軟自然高低隨步。《觀經》云：其地猶如日宮懸處虛空，其地柔軟，下足即凹、舉足便起。又彼國無須彌山及諸山等，《瑞相經》亦說：其佛國土，自然七寶合成其地，不可限量殊特妙好，逾諸十方一切世界。此唯金者，亦文略也。又眾寶妙衣遍有其地，一切人天踐之而行，種種莊嚴以顯殊特也。

The Praise says: The fourth [feature is that] the ground is spread with yellow gold. Because their minds are free from defiled seeds, the ground manifests as yellow gold, naturally soft and yielding, rising and falling in accordance with one's steps. The Contemplation Sūtra says: 'Its ground is like the sun-palace suspended in empty space; the ground is soft, dipping down as one sets foot on it and rising back up as one lifts a foot.' Furthermore, that land has no Mount Sumeru or other mountains. The Auspicious Signs Sūtra also says: 'In that Buddha-land, the ground is naturally composed of the seven jewels; it is immeasurably extraordinary, exquisite, and fine, surpassing all worlds throughout the ten directions.' That here only gold is mentioned is also an abbreviation of the text. Furthermore, exquisite robes of various jewels cover the ground everywhere; all humans and devas walk upon them, and various adornments display its extraordinary magnificence.
