There are a total of 25 beautiful cetasikas divided into four groups. The first 19 are called universal because they will arise with any beautiful citta — that is, with all cittas except the 12 unwholesome and 18 rootless ones. After this large group come three groups of beautiful cetasikas, which are variable factors not necessarily contained in beautiful cittas.
Faith is characterized by trust. It manifests as clarity and removal of the impurities of the mind. Its proximate cause is something to believe in.
Mindfulness means presence of mind, attention to the present. It has the property that it does not float away from the object. Its function is absence of confusion and forgetfulness.
Shame and Fear of wrongdoing both have the function of not doing evil. They manifest as turning away from evil. The proximate cause of shame is self-respect, and the proximate cause of fear of wrongdoing is respect for others.
Non-greed is characterized by the mind’s lack of desire for its object. Its function is non-grasping and its manifestation is detachment. Non-greed is not simply the absence of greed, but also the presence of positive virtues such as generosity and renunciation.
Non-hate has the character of lack of ferocity and non-resistance. Its function is to remove nuisance. Its manifestation is pleasantness. Non-hatred includes positive virtues such as loving-kindness, gentleness, friendship, etc.
Mind-neutrality is a synonym for equanimity — not as a neutral feeling, but as a mental attitude of balance and impartiality. The function of neutrality is to prevent a shortage or excess of something and to prevent partiality. Mind-neutrality treats all beings without discrimination, without preference and prejudice, considering everyone as equal.
The next twelve beautiful universal cetasikas are made up of six pairs, in which one cetasika affects the citta and the other cetasika affects the entire collection of associated cetasikas.
Tranquility has the characteristic of subduing disturbances in the citta and associated cetasikas. Its function is to crush such disturbances. It manifests as peace and is opposed to defilements such as restlessness and worry.
Lightness is characterized by diminishing heaviness in the citta and associated cetasikas. Its function is to crush heaviness. It manifests as non-sluggishness and is opposed to impurities such as sloth and torpor.
Malleability is characterized by diminishing rigidity in the citta and associated cetasikas. Its function is to crush rigidity. It manifests as non-resistance and is opposed to defilements such as wrong view and conceit.
Wieldiness has the function of crushing unwieldiness. It is opposed to the remaining hindrances.
Proficiency has the characteristic of healthiness in the citta and associated cetasikas. Its function is to crush unhealthiness in the citta and associated cetasikas. It is manifested as an absence of disability and is opposed to lack of faith.
Rectitude is characterized by uprightness of citta and associated cetasikas. Its function is to crush tortuousness in the citta and associated cetasikas. It is opposed to hypocrisy, deceit, fraudulence, etc.
Abstinence here includes three beautiful cetasikas which are responsible for deliberate abstinence from wrong speech, wrong action and wrong livelihood. These cetasikas are called right speech, right action and right livelihood.
Right speech is the deliberate abstinence from wrong speech, which includes everything from lying and slander to harsh language and frivolous talk.
Right action is the deliberate abstinence from wrong actions such as violence, killing, theft and sexual abuse.
Right livelihood is the conscious abstinence from wrong livelihood, such as the trade in poisons, drugs, weapons, humans, or animals for slaughter.
The function of the three abstinences is to avoid evil deeds. They are manifested as abstinence from such deeds. They can be considered as the mind’s aversion to wrongdoing.
There are four cetasikas which are called limitless because they must encompass all living beings and thus have a potentially limitless reach. The four limitless cetasikas are loving-kindness, compassion, appreciative joy and equanimity.
Although there are four limitless cetasikas, only two — compassion and appreciative joy — are included here. This is because loving-kindness is a form of the non-hatred cetasika, and equanimity is a form of the mind-neutrality cetasika. Non-hate does not necessarily manifest as loving-kindness. It can also appear in other ways, but when loving-kindness arises in the mind, it happens as a manifestation of the non-hate cetasika . A similar relationship holds between mind-neutrality cetasika and the sublime state of equilibrium and impartiality towards all living beings.
Compassion has the property of promoting the removal of suffering in others. Its function is to not be able to bear the suffering of others. It is expressed as non-cruelty. Its proximate cause is seeing helplessness in those overwhelmed by suffering.
Appreciative joy has the characteristic of delighting in the success of others. Its function is not to envy the success of others. It manifests as the elimination of aversion. Its proximate cause is seeing the success of others.
While non-hatred and neutrality of mind are present in all beautiful cittas, compassion and appreciative joy are present only on occasions when their functions are explicitly exercised.
In the Abhidhamma, the three terms — wisdom, knowledge and non-delusion — are used synonymously. Wisdom is here called a faculty because it predominates in understanding things as they really are.
Wisdom faculty has the characteristic that it penetrates into things according to their intrinsic nature. Its function is to illuminate things objectively. It manifests as non-confusion and its proximate cause is wise attention.
