阿彌陀經疏 1.130

1.130

經曰：「七重行樹皆是四寶」，次釋第三樹同嚴飾，謂皆七寶莊嚴也。若《無量壽經》云：皆以七寶間錯。《清淨覺經》或以四寶百寶一寶莊嚴，隨念即現。若《觀經》云：一一樹皆高八千由旬，其葉華果一一皆作異寶色也。若《無量壽經》說權不言大小，唯佛菩提樹高四百萬里，其本周圍五十由旬，枝葉四布二十萬里，一切眾寶自然合成，彼土天人聞此樹動演出法音，皆得無生深法忍，住不退轉，見嗅及觸皆得適悅，此且形相淨土也。第一義土者，《淨名經》云：無漏法林樹，敷覺意妙華，解脫智慧果。

The sūtra says: 'Seven tiers of trees, all made of the four jewels.' Next is the explanation of the third [point], trees equally adorned; that is, all are adorned with the seven jewels. The Infinite Life Sūtra says: 'All are intertwined with the seven jewels.' The Qingjing jue jing says that they are adorned with four jewels, a hundred jewels, or one jewel, appearing immediately according to thought. The Contemplation Sūtra says: 'Each tree is eight thousand yojanas tall, and its leaves, flowers, and fruits all display the colors of different jewels.' The Infinite Life Sūtra, speaking provisionally, does not specify size, except that the Buddha's Bodhi tree is four million li tall, its trunk measuring fifty yojanas in circumference, its branches and leaves spreading across twenty myriad li, spontaneously formed of all kinds of jewels; when devas and humans of that land hear this tree moving and proclaiming the Dharma sound, all attain the profound anutpattika-dharma-kṣānti and abide in the state of avaivartika, and seeing, smelling, or touching it, all obtain comfort and delight. This is the physical pure land. As for the ultimate land, the Vimalakīrti Sūtra says: 'The groves and trees of āsrava-free dharmas unfold the wondrous flowers of the factors of enlightenment and bear the fruits of liberation and wisdom.'
