大乘義章 16.56

次解七覺。四門分別：一釋其名、二定體具、三分止觀、四明次第。名字如何？經中說之為七覺分，亦名覺支。無漏聖慧名之為覺，念等七種覺中差別名分名支。亦可無學聖智名覺，念等七種能為彼因名分名支。問曰：三十七道品法通是覺分、齊是覺支，何故此七偏名覺支？七覺修道隣於無學，以此近果，為因相顯，故偏對覺說支說分。名義如是（此一門竟）。

Next, the seven factors of awakening (bodhyaṅga) are explained. They are differentiated into four sections: first, explaining their names; second, determining their essential constituents; third, dividing śamatha and vipaśyanā; fourth, clarifying their sequence. What of their names? In the sūtras they are called the seven limbs of awakening (sambodhyaṅga), and also called the branches of awakening. Anāsrava noble prajñā is called "awakening" (bodhi), and the distinctions within awakening such as mindfulness and the rest are called "limbs" (bhāga) or "branches" (aṅga). It may also be that the noble knowledge of the stage of no-more-learning is called awakening, and the seven kinds, mindfulness and the rest, are able to serve as its causes, so they are called "limbs" or "branches." Question: All the dharmas of the thirty-seven factors of awakening are limbs of awakening, and are equally branches of awakening; why are these seven specifically called branches of awakening? The cultivation of the path in the seven factors of awakening borders on the stage of no-more-learning; because this is close to the fruit, its aspect as cause is prominent, and therefore it is specifically designated as branches and limbs with respect to awakening. Such is the meaning of their names. (This concludes the first section.)
