[453] How should the faculties (indriya) be seen in the sense of initial purification (ādivisodhana)?
The faith faculty (saddhindriya) [should be seen] in the sense of resolution (adhimokkha); purity of morality (sīlavisuddhi), in the sense of restraint of faithlessness, is the initial purification of the faith faculty. The energy faculty (viriyindriya) in the sense of exertion; purity of morality, in the sense of restraint of laziness (kosajja), is the initial purification of the energy faculty. The mindfulness faculty (satindriya) in the sense of establishing (upaṭṭhāna); purity of morality, in the sense of restraint of heedlessness (pamāda), is the initial purification of the mindfulness faculty. The concentration faculty (samādhindriya) in the sense of non-distraction; purity of morality, in the sense of restraint of restlessness (uddhacca), is the initial purification of the concentration faculty. The wisdom faculty (paññindriya) in the sense of seeing; purity of morality, in the sense of restraint of ignorance, is the initial purification of the wisdom faculty.
For the five faculties in renunciation (nekkhamma), purity of morality, in the sense of restraint of sensual desire, is the initial purification of the five faculties. For the five faculties in non-ill will, purity of morality, in the sense of restraint of ill will, is the initial purification of the five faculties. … For the five faculties in the path of Arahantship, purity of morality, in the sense of restraint of all defilements (kilesa), is the initial purification of the five faculties. Thus should the faculties be seen in the sense of initial purification.
