The thirteen cetasikas below are common to both beautiful and non-beautiful cittas. They assume the ethical quality given to the citta by the other cetasikas, especially the associated roots. With kammically wholesome cittas they become wholesome, with kammically unwholesome cittas they become unwholesome, and with kammically indeterminate cittas they become kammically indeterminate.
The seven universals are the cetasikas common to all cittas. These factors perform the most basic cognitive functions, without which cognition of an object would be impossible.
Contact here is the cetasika with which the consciousness mentally “touches” the object that has appeared, thereby initiating the entire cognitive process.
Feeling here is the affective state in which the object is experienced. Feeling does not mean feeling as such, but is the mere affective quality of an experience. Other cetasikas only experience the object secondhand, while feeling experiences it directly.
Perception is the perception of the object’s qualities. Its function is to cognize what has previously been perceived. It manifests as the interpretation of the object using the perceived properties.
Volition is the cetasika concerned with the actualization of a goal. Constitutes the will-aspect of cognition. Its characteristic is the state of will, and its function is to accumulate kamma. Volition determines the ethical quality of the action, and is therefore the most important piece in the formation of kamma
One-pointedness here means focusing the mind on its object. It manifests as peace.
Mental life faculty vitalizes the associated mental states. It is characterized by the fact that it sustains them and its function is to cause them to arise.
Attention is responsible for making the mind aware of the object. Its function is to connect the relevant states of mind and the object.
The six cetasikas in this group differ from the universals in that they exist only with certain types of consciousness.
Initial application is the initial application of the mind to the object. Its characteristic is to direct the mind on the object.
Sustained application is continued investigation of the object. Its function is the persistent application of the associated mental phenomena to the object. It manifests itself as the anchoring of these phenomena onto the object.
Decision has the nature of conviction. It manifests as determination.
Energy is the state of being energetic. Its characteristics are support, effort and mobilization. Its function is to support the associated modes.
Zest has the function of refreshing the mind and body. It manifests itself as excitement.
Desire here means desire to perform an action or achieve some result. This kind of desire must be distinguished from desire in the unwholesome sense, that is, from greed and lust.
