阿彌陀經通贊疏 2.25

2.25

贊曰：第二池嚴眾寶。文分為七：第一、七寶池深；第二、八德水滿；第三、金砂作地；第四、玉砌成階；第五、朱閣凌空；第六、寶蓮覆水；第七、結成極樂。此即初也。又者，如前解。七寶者：一金，金有五種，黃者為上，久埋不失，百鍊不輕，從草不違，生於土左右，所以金字象金在土中形。二、銀，易知。三、瑠璃者，梵云吠瑠璃，有五種色，略云瑠璃。四者、玻𭹳者，《智度論》云：出山石窟中，過千年氷化為玻𭹳。淨國無其寒暑，土地無氷，何物化焉？但是石類，非實石也，謂淨土故亦云胝迦。五、車𤦲者，梵云牟娑洛揭拉婆，青白間色也。六、赤真珠者，珠體赤也。七、瑪瑙者，梵云遏濕摩揭婆，此云杵藏，下辨七寶亦依此處。池者，池沼。嚴寶瓔珞砌墁池潭，異種光曜自然嚴顯。《瑞應經》云：其池縱廣深淺或十由旬乃至百千由旬，其池岸上有栴檀樹，華葉垂布香氣馥薰也。

The Commentary says: Second, the ponds adorned with manifold jewels. The text is divided into seven parts: first, the depth of the ponds of the seven jewels; second, their fullness with water of eight virtues; third, golden sand forming the ground; fourth, jade masonry forming the steps; fifth, vermilion pavilions soaring into the air; sixth, jeweled lotuses covering the water; seventh, concluding the establishment of Sukhāvatī. This is the first. 'Furthermore' is explained as before. Regarding the seven jewels: first, gold. Gold has five types, of which the yellow is supreme; buried for a long time it does not perish, smelted a hundred times it does not lose weight, it does not disobey plants, and it is born to the left and right of earth; hence the character for 'gold' (金) depicts the shape of gold inside earth. Second, silver, easily understood. Third, lapis lazuli: in Sanskrit, vaiḍūrya; it has five colors, abbreviated as liúlí. Fourth, crystal: the Zhidu lun says that it comes from mountain caves, formed when ice over a thousand years turns into crystal. The pure realm has no cold or heat, and the land has no ice; how could anything transform into it? It is merely a kind of stone, not actual stone; because it is the Pure Land, it is also called phatiga [sphaṭika]. Fifth, giant clam shell: in Sanskrit, musāragalva, of alternating blue-green and white colors. Sixth, red pearls: the body of the pearl is red. Seventh, agate: in Sanskrit, aśmagarbha, translated here as 'pestle receptacle'. The discernment of the seven jewels below also follows this. Regarding 'ponds': pools and reservoirs. Adorned with jeweled necklaces, masonry lines the ponds and basins, their varied kinds of radiance naturally adorning and manifesting. The Ruiying jing says: the length, breadth, and depth of the ponds are ten yojanas up to hundreds of thousands of yojanas; on the banks of the ponds are sandalwood trees, their flowers and leaves hanging down, their fragrant scent richly perfuming.
