The mental factor that causes the mental activity to face an object or to go in its direction.
The subsidiary awareness (mental factor) that causes the mental activity to face an object or to go in its direction. In general, it moves a mental continuum to cognitively take an object. It is equivalent to mental karma and, according to Sautrantika, Chittamatra, Svatantrika-Madhyamaka, and the non-Gelug Prasangika-Madhyamaka schools, it is equivalent to physical and verbal karmas as well.
