masc nom sg of cetosamathamanuyutta (adj)
Analysis. ceto-samatha-manuyutta: 'mind' (ceto, from cetas) + 'tranquillity, calming' (samatha, from sam- 'together' + √atha 'stop', bringing mental states into stillness) + 'yoked to, devoted to' (manuyutta, from manu- 'thinking' + yutta 'joined', or more likely a past participle meaning 'attached to, engaged with'). The compound denotes devotion to the practice of calming the mind.
Etymology. ceto- from cetas (mind, heart, consciousness); samatha from sam- (together, completely) + atha (to stand still, stop), cognate with Sanskrit sthā and English stand—the image is of thought brought to rest and stillness; manuyutta combines manu (thinking, intent) with yutta (yoked, joined), or is a past participle of man- + yu- meaning 'applied to, devoted to'.
