妙法蓮華經玄贊 2.230

2.230

“Vidyācaraṇasampanna” is “accomplished in clear knowledge and conduct.” “Clear knowledge” refers to the three clear knowledges: first, the knowledge of remembering past abodes; second, the knowledge of the birth and death [of beings]; third, the knowledge of the exhaustion of outflows. “Conduct” refers to preventive conduct and active conduct. “Active conduct” refers to the purification of the three karmas and actualized right livelihood. Moreover, the four kinds of higher mental phenomena dwelling in bliss in the present life are dwelling conduct; both of these are subsumed under active conduct. Guarding the sense gates closely is preventive conduct. Both of these conducts and the three clear knowledges are all perfected. Thereby the Tathāgata displays the three unguardeds and the state of non-forgetfulness; by not committing errors, he attains worldly dhyāna and prevents self-mortification. Here, “by not committing errors” is because the three karmas are pure; that is the three unguardeds, and because he closely guards the sense gates, possessing non-forgetfulness, he attains worldly dhyāna, dwelling in bliss in the present life, and prevents self-mortification. Therefore he is called “accomplished in clear knowledge and conduct.”
