cetasika]: Mental concomitant (see vedana, sañña, and sankhara).

mental concomitants

(p) mental factor arising with consciousness. The second paramattha dhamma is cetasika which is nama. As we have seen, citta experiences an object: seeing has what is visible as its object, hearing has sound as its object, thinking has what is thought about as its object. However, there is not only citta, there are also mental factors, cetasikas, which accompany a citta. One can think of something with aversion, with a pleasant feeling, with wisdom. Aversion, feeling and wisdom are mental phenomena which are not citta; they are cetasikas which accompany different cittas. There is only one citta at a time, but there are several cetasikas (at least seven) arising together with the citta and falling away together with the citta, citta never arises alone. For example, feeling, in Pali: vedana, is a cetasika which arises with every citta. Citta only knows or experiences its object; it does not feel.
