Bujjhaka (adjective) [from budh] intelligent, prudent, judicicus, in a° Dīp IX 17, foolish, imprudent, unmindful of their own interest (translation suggested by E. Hardy as preferable to Oldenberg's "unnoticed"). Morris, JPTS 1893, 69 suggests "not fighting," thus making abujjhaka = avujjh° = ayujjh° (of yudh).
