大乘起信論義疏 1.17

1.17

言隨文釋者，文中有二：一者總表；二者問「有何因緣」以下，別表其意。就第一中有二：一者總勸起信；二者從「有五分」以下，總判科文。言「論曰」者，馬鳴菩薩說法之辭也。言「有法」者，是所說法也，謂七八識。言「能起」者，能應起也。言「摩訶衍」者，是其胡語。此方翻者，摩訶言大，衍是言乘。大乘之言，如先說也。言「信根」者，信是諸行之根本也，故言應起大乘信根也。何以故？此法中信者即是大乘信故，即是最勝感佛近因。故經說言「復有正因，所謂信心首楞嚴等」也。信者是其報佛正因，首楞嚴者亦名佛性，即是法佛之正因也。言「是故應」者，總結釋之。自下第二科文。「說有五分」者，是總舉也。「因緣分」等，是其別釋。文題可知。

Regarding "explaining according to the text": within the text there are two parts. First, a general presentation; second, from the question "For what reason..." onward, a specific presentation of the intention. Within the first part there are two: first, a general exhortation to give rise to faith; second, from "there are five parts" onward, a general division of the text's sections. As for "The treatise states": these are the words spoken when Bodhisattva Aśvaghoṣa expounded the Dharma. As for "There is a dharma": this is the dharma that is taught, namely the seventh and eighth consciousnesses. As for "can give rise": it can appropriately give rise [to it]. As for "mahāyāna": this is a foreign word. In translation into this land, mahā means "great" and yāna means "vehicle". The words "Great Vehicle" (Mahāyāna) are as explained previously. As for "root of faith": faith is the root of all practices; therefore it says one should give rise to the root of faith in the Mahāyāna. Why is that? Because faith in this dharma is faith in the Mahāyāna, which is the most supreme immediate cause for affecting [the attainment of] Buddhahood. Therefore a sūtra says: "Furthermore, there is a direct cause, which is called the mind of faith, the Śūraṅgama, and so forth." Faith is the direct cause of the saṃbhogakāya Buddha; the Śūraṅgama is also called Buddha-nature, which is the direct cause of the dharmakāya Buddha. As for "Therefore, one should...": this is a concluding summary and explanation. Next, the second part divides the text. "It is said that there are five parts": this is a general citation. "The section on reasons", and so forth, are the specific explanations. The titles of the text are self-evident.
