Zhènquàn yòngxīn 鎭勸用心
Settled-Earnest Exhortation on Mental Disposition by 證空 Shōkū (記)
About the work
A single-fascicle short doctrinal exhortation in compressed couplet-style prose by 證空 Shōkū. The title’s chinkan 鎭勸 — “settled-earnest exhortation” — and yōjin 用心 — “use-of-mind, mental disposition” — together signal the work’s genre: a kashō (戒勸 — admonitory) text addressed to practitioners on the proper mental orientation for nenbutsu praxis. The text is brief but doctrinally dense, with each couplet encoding a specific practical-mental instruction.
Abstract
The opening couplets exemplify the style: “Sleeping, illumined: a single night on the bench of the retributive-Buddha’s gratitude-cause — straight away illumined. Waking, sunset: a single day in the inner-realization of the broad vow — straight away sunset. The power-of-faculties is obstinate — do not give rise to retrospective anxiety: the Buddha’s vow to embrace the inferior-faculty is already accomplished. The action-task is meagre — do not entertain doubt-as-a-fox: the sūtra’s word that ten thoughts suffice is the very proof.” (睡而明一夜報佛酬因之榻即明。覺而暮一日弘願内證之裡即暮 …).
The text proceeds through admonitions against (i) fearful self-doubt about whether one’s practice or faculties are adequate to attain rebirth; (ii) over-evaluation of one’s own good-faculties (which can lead to jiriki self-power complacency); (iii) fretting over the goodness or badness of one’s life-circumstances; and (iv) spiritual exhaustion in the practice — each addressed by an appeal to the Original Vow’s already-accomplished salvific work. The doctrinal substance is the standard Seizan-line kihō ichinyo (機法一如) and ichinen go-jō (一念業成) teaching, here presented in compressed exhortatory form.
Genre. The work belongs to the medieval Pure-Land kashō / yōjin (admonition / mental-disposition) genre, of which other notable examples include Genshin’s KR6t0393 Ōjōyōshū mental-discipline sections and Kakuban’s Mitsugen yōjin. Shōkū’s contribution is distinguished by the paired-couplet prose-style — each couplet using parallelism (對偶) to oppose a negative admonition with a positive doctrinal counter — which became a stylistic model for later Seizan-line catechetical writing.
Date. Shōkū’s mature period; no internal precise date.
