2.56

「離憂」下，標示禪義。「初禪」下，約四教明禪也。初約四禪即藏通，後得六根互用即別圓。他住初禪等者，約支林功德以辨也。初禪五支：一覺、二觀、三喜、四樂、五一心。二禪四支：一內淨、二喜、三樂、四一心。三禪五支：一捨、二念、三喜、四樂、五一心。四禪四支：一不苦不樂、二捨、三念清淨、四一心。心與定法名一心支，四禪俱有心及定法，故具有此支。三禪有喜支，今云除喜，未詳。「六根具禪」者，從便言六，意具顯眼。「究竟盡」者，藏通究竟盡見思、別盡塵沙，圓盡無明，當分而論各名究竟。

From "departing from sorrow" downward marks and indicates the meaning of dhyāna. From "the first dhyāna" downward clarifies dhyāna in terms of the four teachings. First, in terms of the four dhyānas, it refers to the Tripiṭaka and shared [teachings]; later, obtaining the mutual functioning of the six faculties refers to the distinct and perfect [teachings]. "Others abide in the first dhyāna," and so forth, is distinguished in terms of the virtues of the limbs. The first dhyāna has five limbs: 1. vitarka, 2. vicāra, 3. joy, 4. bliss, 5. one-pointedness of mind. The second dhyāna has four limbs: 1. internal purification, 2. joy, 3. bliss, 4. one-pointedness of mind. The third dhyāna has five limbs: 1. equanimity, 2. mindfulness, 3. joy, 4. bliss, 5. one-pointedness of mind. The fourth dhyāna has four limbs: 1. neither-pain-nor-pleasure, 2. equanimity, 3. purification of mindfulness, 4. one-pointedness of mind. Mind and the dharma of concentration are named the limb of one-pointedness of mind; all four dhyānas possess both mind and the dharma of concentration, so they all possess this limb. The third dhyāna has the joy limb; now saying "excluding joy" is not yet clear. "The six faculties possessing dhyāna": it speaks of six for convenience, but the intention is fully to reveal the eye. "Utmost exhaustion": the Tripiṭaka and shared completely exhaust [the defilements of] views and thought; the distinct exhausts [those numerous as] dusts and sands; the perfect exhausts fundamental ignorance; discussed according to their respective scopes, each is named utmost.
