仁王護國般若波羅蜜多經疏 3.524

3.524

解曰：能鎮毒龍者，鎮惡龍鬼德。謂摩尼寶鎮諸毒龍，止惡風雨；鎮惡鬼神，不行疾疫，不令非法夭害有情。能遂人心者，遂人所求德。謂摩尼寶，若有所求，衣服飲食及諸珍寶，所須皆得。能應輪王者，輪王意珠德。謂摩尼寶應轉輪王，隨王之意所須皆得。能令難陀等者，龍降甘雨德。謂摩尼寶能令難陀此翻云喜、跋難陀者此云賢喜，等者等和修吉等諸大龍王，隨順法行，降霔甘雨、潤澤草木。若於闇夜者，光照天地德。謂摩尼寶若於闇夜，置高幢上，光照天地明如日出，無所不見。從此第三結申般若。

Exposition: 'It can quell venomous nāgas' is the virtue of quelling evil nāgas and ghosts. It means that the maṇi jewel quells all venomous nāgas, stopping unwholesome winds and rain; it quells evil ghosts and spirits, preventing pestilences from circulating, and not letting unrighteousness prematurely harm sentient beings. 'It can fulfill whatever human hearts desire' is the virtue of fulfilling what humans seek. It means that through the maṇi jewel, if there is anything sought—clothing, food and drink, and all precious gems—everything required is obtained. 'It can respond to a wheel-turning king' is the virtue of being the wish-fulfilling jewel of a wheel-turning king. It means that the maṇi jewel responds to a cakravartin, so that whatever corresponds to the king's wish is obtained as needed. 'It can cause Nanda and others' is the virtue of causing nāgas to send down sweet rain. It means that the maṇi jewel can cause Nanda (translated here as 'Joy'), Upananda (translated here as 'Virtuous Joy'), and other [kings], et cetera including Vāsuki and other great nāga kings, to comply with dharmic conduct, pour down sweet rain, and moisten grasses and trees. 'If placed upon a high banner in the dark night' is the virtue of illuminating heaven and earth with light. It means that if the maṇi jewel is placed upon a high banner in the dark night, its light illumines heaven and earth as bright as the rising sun, leaving nothing unseen. From here on is the third, concluding by applying it to prajñā.
