摩訶止觀 9.126

9.126

○第九、明念佛發者：或發念佛，次發諸禪；或因諸禪而發念佛。於坐禪中忽然思惟諸佛功德無量無邊，不可思議，信敬慚愧，深生慕仰。存想諸佛有大神力、有大智慧、有大福德、有大相好。如是相好從此功德生；如此相好從彼功德生。如是相好有如此福德；如此相好有如彼福德。知相體，知相果，知相業，一一法門照達明了，深解相海而無疑滯。定心怗怗，亦不動亂；安住此定，漸漸轉深，忽發麁細住、欲界、未到，進入初禪等。

Ninth, explaining the arising of mindfulness of the Buddha: either mindfulness of the Buddha arises and then the various dhyānas arise, or because of the various dhyānas mindfulness of the Buddha arises. While seated in dhyāna, one suddenly contemplates the immeasurable, boundless, and inconceivable merits of the Buddhas, giving rise to profound faith, reverence, shame, and yearning admiration. One visualizes the Buddhas possessing great spiritual power, great wisdom, great blessing and merit, and great marks and signs. Such marks and signs arise from this merit; such marks and signs arise from that merit. Such marks and signs possess this blessing and merit; such marks and signs possess that blessing and merit. One knows the essence of the marks, knows the fruits of the marks, and knows the karmic actions of the marks; illuminating and comprehending each and every Dharma gate clearly, one deeply understands the ocean of marks without doubt or impediment. The settled mind is calm and peaceful, without agitation or distraction; abiding peacefully in this absorption, it gradually deepens, suddenly giving rise to the coarse and fine abide, the desire realm [concentration], the threshold [concentration], and advancing into the first dhyāna and beyond.
