大般涅槃經集解 69.30

69.30

案僧亮曰：一切法，謂經法也。能濟窮乏，謂之寶。無寶不備，名藏也。此經說佛性果，能出生死，名寶。說果則無法不常，說因則無法非性，名藏也。自大海以下譬藏，猛風以下譬寶也。

Sengliang states: 'All dharmas' refers to the dharmas of the sūtra. Being able to rescue the destitute is called a 'treasure'. Having every treasure without lack is called a 'storehouse'. This sūtra explains the fruit of the buddhadhātu, which can transcend saṃsāra; this is called 'treasure'. Explaining the fruit, no dharma is not permanent; explaining the cause, no dharma is not the nature; this is called 'storehouse'. From 'the great ocean' onward is a metaphor for the storehouse; from 'fierce wind' onward is a metaphor for the treasure.
