摩訶止觀 4.88

4.88

運此十懺時，深觀三諦；又加事法，以殷重心，不惜身命，名「第二健兒」。是名事理兩懺，障道罪滅，尸羅清淨，三昧現前，止觀開發。事戒淨故，根本三昧現前，世智、他心智開發。無生戒淨故，真諦三昧現前，一切智開發。即假戒淨故，俗諦三昧現前，道種智開發。即中戒淨故，王三昧現前，一切種智開發。得此三諦三昧，故名「王三昧」，一切三昧悉入其中。又能出生一切諸定，無不具足，故名為「止」；又能具足一切諸智，故名為「觀」。故知持戒清淨，懇惻懺悔，俱為止觀初緣，意在此也。

When employing these ten repentances, one profoundly contemplates the three truths. In addition, one applies ritual practice with a deeply earnest mind, not sparing bodily life; this is called the 'second stalwart person.' These are called the two repentances of phenomena and principle. Sins that obstruct the Path are extinguished, morality is purified, samādhi becomes manifest, and calming and contemplation are developed. Because the morality of phenomena is purified, fundamental samādhi becomes manifest, and worldly knowledge and the knowledge of others' minds develop. Because the morality of non-arising is purified, the samādhi of the true truth becomes manifest, and the knowledge of all phenomena (sarvajñatā) develops. Because the morality identical to the provisional is purified, the samādhi of the conventional truth becomes manifest, and the knowledge of the aspects of the Path develops. Because the morality identical to the middle is purified, the king of samādhis becomes manifest, and the knowledge of all modes (sarvākārajñatā) develops. Having obtained the samādhi of these three truths, it is called the 'king of samādhis,' for all samādhis completely enter into it. Furthermore, it is able to produce all concentrations, lacking none; therefore it is called 'calming.' Furthermore, it is fully endowed with all kinds of wisdom; therefore it is called 'contemplation.' Hence we know that pure observance of the precepts and earnest repentance are both the preliminary conditions for calming and contemplation; such is the intent here.
