緣事 (1) Things and affairs as conditions--as karma. (2) The consciousness that fully believes in the perfect connection between cause and effect. (3) The matters concerned with one's life; the things one has to do in his/her daily life; one's business. (4) The objects cognized by the mental consciousness. The objective aspect(xiangfen) 相分 of the four aspects (sifen 四分) of Consciousness-only.

To lay hold of, or study things or phenomena, in contrast to principles or noumena, cf. 緣理; meditation on the Buddha's nirmāṇakāya and saṃbhogakāya, in contrast with the dharmakāya. 

信有因果報應的事實，叫做緣事，若信非因非果法性之妙理，則叫做緣理。
