[945] **"When one would know the turbidity of the mind (yadāvilattaṃ manaso vijaññā)"** — "When" (yadā): at whatever time. "Of the mind (manaso)": that which is mind (citta), mentality (mano), mentation (mānasa), heart (hadaya), the lucid (paṇḍara), mind (mano), the mind base (manāyatana), the mind faculty (manindriya), consciousness (viññāṇa), the aggregate of consciousness (viññāṇakkhandha), the mind-consciousness element arising from that (tajjā manoviññāṇadhātu).
Through bodily misconduct the mind becomes turbid, stirred up, agitated, struck, shaken, whirling, unstilled; through verbal misconduct, through mental misconduct, through lust (rāga), through hatred, through delusion, through anger, through grudge, through denigration, through domineering, through envy, through avarice, through deceit, through hypocrisy, through obstinacy, through contentiousness, through conceit, through excessive conceit, through intoxication, through heedlessness — through all defilements (kilesa), all misconduct, all distress, all fevers, all torments, all unwholesome volitional formations (akusalābhisaṅkhāra) — the mind becomes turbid, stirred up, agitated, struck, shaken, whirling, unstilled.
"When one would know the turbidity of the mind": one should know, understand thoroughly, discern, recognize distinctly, and penetrate the turbid state of the mind (citta) — hence, "when one would know the turbidity of the mind."
