Co-workers and messengers may be either conscious or unconscious ones. The entrusting of commissions is considered honorable, but unconscious co-workers usually do not even know when they have been inspired by a commission. They proceed in accord with a command unknown to them, transmitting something or forewarning someone, but they themselves do not know where is the beginning and where the end of their mission. There are many such messengers; they differ according to their condition, but none the less they do not tarry. Also, there are particular silent commissions, when it is needful to exert influence, not by a word, but by silence. (BR (opens in new tab), 66)
