masc nom sg of passaddha (pp)
Etymology. From pa- (forward, forth) + √sad (sit, settle), literally 'settled forth' or 'thoroughly settled'; related to Sanskrit prasanna 'clear, bright', from pra- + sad-. The sense evolves from the concrete image of settling down completely into the abstract meaning of mental ease and tranquility.
