首楞嚴義疏注經 7.33

7.33

What is practiced in the three seven-day periods differs for each. First, one prostrates to the buddhas, circumambulates the altar, recites the mantra, and performs the practice; here one must carry out the five repentances, prostrating to the buddhas to plead for compassionate empowerment and repenting so as to leave behind the obstacle of pride and the like. Next, setting aside the previous practice, one constantly generates great vows, thus making the mind vast and leaving behind the obstacle of narrow inferiority. Finally, one single-mindedly recites and upholds the heart-mantra, empowering the portal of practice and guarding against all demonic events. Through the auxiliary cultivational power of these three terms, resonance and response interact along the Path, and one visibly receives the Buddha's response in crowning touch and comfort.
