Kāmāvacaracittas

Kusala vs. Akusala Cittas

What Makes a Citta Kusala / Akusala?

The association with cetasikas such as lobha, dosa, and moha which produce bad results, oppress the mind and body makes a citta unwholesome.

Association with cetasikas such as alobha, adosa, amoha, faith, mindfulness, wisdom, lovingkindness, and so on, which produce good results, satisfy and develop the mind and body, makes a citta wholesome.

4 Definitions of Akusala

Association: associates lobha, dosa, or moha
Immediate effects: disturbs mental peace (1), oppresses the body (2)
Results: produces bad results in the future

4 Definitions of Kusala

Association: associates alobha, adosa, or amoha
Immediate effects: tranquilizes the mind (1), supports and lightens the body (2)
Result: produces good results

Hetu (root)

The cetasikas which firmly take the object or that have a firm footing on the object. The cetasikas that facilitate vedanā to feel the object well.

3 Akusala Hetus

Lobha, dosa, and moha

3 Kusala (Sobhana) Hetus

Alobha, adosa, and amoha Note: they can be kusala, vipāka, or kiriya.

Akusalacittas

How are Akusalacittas Classified?

According to the 3 akusalahetus, resulting in 3 types as lobhamūla, dosamūla, and mohamūla.

Lobhamūlacittas

Lobha

What lobha is: greed that is attached to the object, craves for and thirsts after it. It grasps at even trifling qualities of the object and can occur in any intensity from subtle liking to holding on tenaciously.

Other terms: like, crave, desire, wish for, need, want, cling to, attach to, thirst for.

How are lobhamūlacittas classified? According to vedanā (somanassa or upekkhā), sampayoga (diṭṭhi sam/vipayutta), and saṅkhāra (sa/asaṅkhārika).

Prompted (Sasaṅkhārika) or Unprompted (Asaṅkhārika)

Prompted can be bodily, verbal, or mental. Prompted means there is reluctance. Prompted is not always associated with thīnamiddha, but if there is thīnamiddha, it is surely prompted.

Payoga (instigation, prompting, force) — mostly external
Upāya (expedient) — can be either external or internal

Asaṅkhārika ⇒ sasaṅkhārika: possible Sasaṅkhārika ⇒ asaṅkhārika: not possible

3 Types of Ārammaṇarasa (Flavor of the Object)

Iṭṭha (desirable): ati iṭṭha, iṭṭhamajjhatta
Aniṭṭha (undesirable): aniṭṭhamajjhatta, atianiṭṭha
Majjhatta (neutral): slightly desirable or slightly undesirable

Ārammaṇarasa is objective, but a wise being can cognize according to his will.

Vedanā

What is vedanā? That which experiences, feels, or tastes the desirable, undesirable, or neutral flavor of the object.

Why is vedanā separated into kāyika and mānasika under indriyabheda? Because the vedanā that arises due to bodily contact is particularly different.

Why is vedanā an indriya? Because it is the principal reality in the department of cognition responsible for feeling the taste of the object — citta cannot perform such function without it.

There are 22 indriyas.

Dosamūlacittas

Dosa is that which opposes, resists, dislikes, fears, or hates the object. Dosa is also called ‘paṭigha’ (ill-will) because of the nature of clashing.

Dosamūlacittas are classified according to what?

Saṅkhāra (prompted or unprompted)

What other cetasikas occasionally associate dosamūlacittas?

Issā (envy), macchariya (stinginess), or kukkucca (remorse).

Dosamūlacittas arise when committing seven of the ten courses of unwholesome actions:

Pāṇātipāta (killing)
Adinnādāna (stealing)
Musāvāda (lying)
Pisuṇavācā (slandering)
Pharusavācā (harsh speech)
Samphappalāpa (vain talk)
Byāpāda (wishing others’ death)

Mohamūlacittas

Moha (Delusion): that which darkens the mind making it incapable of realizing the object properly. Moha is an akusalasādhāraṇa cetasika — present in all unwholesome consciousnesses but very strongly in delusion rooted ones.

2 cetasikas that help classify mohamūlacittas

Vicikicchā (skeptical doubt) and uddhacca (restlessness).

3 reasons for mohamūlacitta being always accompanied by neutral feeling

Moha conceals the nature of the object
Vicikicchā has no certainty about the object
Uddhacca shakes due to excessive restlessness

prompted or unprompted?

According to Ledi: they are never prompted but always unprompted since they naturally/spontaneously occur in beings.
