述曰：「界」者，藏義，無為功德涅槃所藏，有為功德菩提所含；或是因義，或為所緣，或為增上，展轉傳說為利益等，謂體能生五乘世、出世間利樂事業，或為緣生他利樂事。何故經云在纏名如來藏，出纏名法身？此中出纏方名為藏。彼約位，此約體；或彼依有障、無障以辨法門，此明本末，故不相違。即是總解第一句訖。

The Commentary states: 'Dhātu' means storehouse: unconditioned merits are stored by nirvāṇa, and conditioned merits are contained by bodhi. Or it has the meaning of cause, whether serving as an objective condition or as an activating condition, successively transmitted to bring about benefit and so forth—meaning that its essence can produce the beneficial and joyful affairs of the five vehicles, both worldly and supramundane, or serve as a condition to produce beneficial and joyful affairs for others. Why do sūtras say that while in entanglement it is named tathāgatagarbha, and when free from entanglement it is named the dharmakāya? Here, only when free from entanglement is it called a storehouse. That is according to stage; this is according to substance. Or that relies on having obstructions versus being unobstructed to distinguish the Dharma portals; this clarifies the root and the branch, and therefore they do not contradict each other. This concludes the overall explanation of the first line.
