大方廣佛華嚴經疏 56.15

56.15

第五「善男子從此下」指示後友。六十由旬者，修六度行，淨六根故。聚落名海岸者，是往楞伽山之道，次南海北岸故。然楞伽梵言，此云難往。又含四義：一種種寶性所成，莊嚴殊妙故；二有大光明，映日月故；三高顯寬廣故；四伽王等居，佛復於此開化群生，作勝益事故。然體即是寶，具斯四義，名無上寶，存以梵音。此山居海之中，四面無門，非得通者莫往，故云難往。表修行之住，是入智海，絕四句、離分別之道故。比丘善住者，身住虛空故，表此住中觀一切法如虛空無處所故。亦比丘者，入道未久，宜依僧故。又初念佛、次聞法，今依僧修，三寶吉祥為所依故。

Fifth, from 'Good man, from here' onward, he indicates the subsequent spiritual friend. 'Sixty yojanas' refers to cultivating the practices of the six pāramitās to purify the six sense faculties. The settlement is named Shore (Sāgara-tīra) because it is the way toward Mount Laṅkā, situated on the northern shore of the southern ocean. Now, the Sanskrit word 'Laṅkā' is translated here as 'Hard to Reach.' It also contains four meanings: first, it is formed of various precious natures, adorned and exceptionally wondrous; second, it has great light that outshines the sun and moon; third, it is lofty, prominent, wide, and vast; fourth, kings of the yakṣas and others dwell there, and the Buddha also instructed and transformed living beings there, performing superior and beneficial deeds. Its substance is indeed gems, and possessing these four meanings, it is called 'Supreme Gem,' retaining the Sanskrit phonetics. This mountain sits in the midst of the ocean, without gates on its four sides, and none but those who have attained spiritual penetrations can reach it; hence it is called 'Hard to Reach.' This symbolizes that the abode of cultivation is the path of entering the ocean of wisdom, transcending the four propositions and departing from conceptual discrimination. As for the monk Supratiṣṭhita (Good Abiding), his body abides in empty space, symbolizing that in this abode one contemplates all dharmas as like empty space, having no spatial location. He is also a monk because, not long after entering the path, one ought to rely on the Saṅgha. Moreover, first was recollecting the Buddha, next was hearing the Dharma, and now one relies on the Saṅgha to cultivate, taking the auspiciousness of the Triratna as one's refuge.
