佛說仁王般若波羅蜜經 2.30

2.30

「復次，勝達菩薩，於順道忍，以四無畏，觀那由他諦內道論、外道論、藥方、工巧、呪術故，我是一切智人；滅三界疑等煩惱故，我相已盡；知地地有所出，故名出道；有所不出，故名障道；逆三界疑。修習無量功德故，即入斯陀含位。復集行八阿僧祇劫中行諸陀羅尼門故，常行無畏觀不去心。

“Furthermore, the Victorious-Comprehending Bodhisattva, regarding the patience of compliance with the path, uses the four fearlessnesses to contemplate nayutas of truths, internal treatises, external treatises, medicinal prescriptions, crafts, and incantations; thus [they realize]: ‘I am an omniscient person.’ Having extinguished defilements such as doubt in the three realms, the characteristic of a self is already exhausted. Knowing that on ground after ground there is emergence, it is called the path of emergence; knowing that there is non-emergence, it is called the obstructing path; they oppose the doubts of the three realms. Cultivating limitless merit, they immediately enter the sakṛdāgāmin position. Further accumulating practices over eight asaṃkhyeya kalpas through practicing various dhāraṇī gates, they constantly maintain the contemplation of fearlessness without letting it leave their minds.
