The Inseparable Operation of Citta and Cetasika

The mind dharmas must rely on the mental factors dharmas to manifest and function; the function of the mind dharmas is the function of the mental factors dharmas, and the function of the mental factors dharmas is the function of the mind dharmas. The mental factors dharmas must accompany the mind dharmas instant by instant; the two cannot be separated for even an instant. The discernment of the mind dharmas is achieved in two ways: one is realized through the functioning of the mental factors dharmas, and the other is accomplished through the Buddha-nature formed by the seeds of the seeing-element.
