觀音義疏 2.79

2.79

夜叉，此云捷疾，此有三處，海島、空中、天上，傳傳相持，不得食人，佛初成道及說法傳唱至天。乾闥婆，此云香陰，帝釋樂神，在須彌南金剛窟住，天欲作樂，其心動。什師云：「在寶山中住，身有異相。」即上奏樂也。

Yakṣas: translated here as 'swift'. These dwell in three places: ocean islands, the sky, and the heavens. Holding [their boundaries] successively, they are not permitted to eat humans. When the Buddha first attained awakening and preached the Dharma, their proclamations reached up to the heavens. Gandharvas: translated here as 'fragrance-aggregate'. They are Śakra's music deities, dwelling in the vajra cave south of Mount Sumeru; when the gods wish to make music, their minds are moved. Master Shi says: 'Dwelling in the jewelled mountains, their bodies have unusual marks.' They then ascend to play music.
