阿彌陀經要解 1.40

1.40

欄楯以嚴際畔，羅網以嚴空界，行樹以嚴露地。各言七重者，表七科道品。皆是四寶者，表常樂我淨四德。周匝圍繞者，彼土佛及菩薩并諸聲聞其數無量，則有無量住處，亦有無量七重欄楯羅網行樹遍滿彼國，處處莊嚴不可窮盡，故云周匝圍繞也。同居淨土此等莊嚴，則是增上善業所感，亦是圓五品觀所感，以緣生微妙五塵為體。方便淨土此等莊嚴，則是即空觀智所感，亦相似三觀所感，以妙真諦無漏五塵為體。實報淨土此等莊嚴，則是妙假觀智所感，亦分證三觀所感，以妙俗諦無盡五塵為體。常寂光土此等莊嚴，則是即中觀智所感，亦是究竟三觀所感，以妙中諦稱性五塵為體。欲令易解作此分別，得意為言，四土莊嚴一一無非因緣生法，一一無不即空假中。下皆倣此，不復繁述。

The railings adorn the boundaries; the netting adorns the sky; the rowed trees adorn the open ground. Each being sevenfold signifies the seven categories of the requisites of enlightenment. Being made entirely of the four jewels signifies the four virtues of permanence, bliss, self, and purity. 'Surrounding it all around': in that land, the Buddhas, bodhisattvas, and śrāvakas are measureless in number, so there are measureless dwelling places, and likewise measureless sevenfold railings, netting, and rowed trees filling that realm, with adornments everywhere that cannot be exhausted; hence it is said to 'surround it all around'. In the pure Land of Cohabitation, such adornments are brought about by superior good karma, and also brought about by the contemplation of the perfect five grades; they take the subtle, five sensory objects born of conditions as their substance. In the pure Land of Expediency, such adornments are brought about by the contemplative wisdom of realizing emptiness, and also by the conforming three contemplations; they take the outflow-free five sensory objects of the wondrous truth of absolute reality as their substance. In the pure Land of Real Reward, such adornments are brought about by the contemplative wisdom of the wondrous provisional, and also by the partially realized three contemplations; they take the inexhaustible five sensory objects of the wondrous conventional truth as their substance. In the Land of Eternally Quiescent Light, such adornments are brought about by the contemplative wisdom of realizing the middle, and also by the ultimate three contemplations; they take the five sensory objects that accord with nature of the wondrous middle truth as their substance. To make it easy to understand, this distinction is made; but to speak from grasping the core meaning, the adornments of the four lands are each without exception phenomena born of causes and conditions, and each without exception is identical to emptiness, the provisional, and the middle. The explanations below all follow this model and will not be repeated at length.
