南傳佛教心法AI資料提供：
南傳佛教（以阿毗達磨/論藏體系為核心，
特別是《勝義阿毗達磨集集論》即《阿毗達磨攝義論》）將一切法分為四種勝義諦（Paramattha）：心法、心所法、色法、涅槃。
其中，心法（Citta） 指的是「知覺目標的意識本體」或「知境的作用」。
一、 心法的核心定義與特性
單一性與多樣性：從勝義諦（究竟法）來看，心法只有一種，即「知覺目標（所緣）的能力/作用」。
但依據其相應的心所、界（欲界、色界、無色界、出世間）及業性（善、不善、異熟、唯作），可細分為 89種心（簡略分類）或 121種心（詳細分類）。
生滅迅速：心法極為迅速地生起與滅去（一彈指間有數萬億個心識生滅），
每一剎那包含生（Uppāda）、住（Thīti）、滅（Bhaṅga）三個小剎那。
心心所相應：心法絕不單獨生起，每次生起必有相應的「心所法（Cetasika）」伴隨（如觸、受、想、命根等），心像是指揮官或主題，
心所則是具體的心理狀態與作用。
二、 心法的八十九種分類（89 Citta）
南傳阿毗達磨將89心依界與性質劃分如下：
1. 欲界心（45種）
不善心（12種）：與貪、瞋、痴相關的心（貪根心8、瞋根心2、痴根心2）。
無因心（18種）：不與善/不善因相應的心，包含五門轉向心、雙五識（眼耳鼻舌身識）、領受心、推度心、確定心、意門轉向心、笑心等。
欲界美麗心（24種）：欲界中的善心（8）、異熟心（8）、唯作心（8）。
2. 色界心（15種）
對應四禪八定中的色界禪定狀態：
色界善心（5種）：初禪至五禪善心。
色界異熟心（5種）：初禪至五禪異熟心（果報）。
色界唯作心（5種）：阿羅漢入色界禪的心。
3. 無色界心（12種）
對應四無色定（空無邊處、識無邊處、無所有處、非想非非想處）：
無色界善心（4種）
無色界異熟心（4種）
无色界唯作心（4種）
4. 出世間心（8種 / 若開合廣說則為40種）
超越三界、以涅槃為所緣的心：
道心（4種）：須陀洹道心、斯陀含道心、阿那含道心、阿羅漢道心（斷除煩惱）。
果心（4種）：須陀洹果心、斯陀含果心、阿那含果心、阿羅漢果心（體驗斷除煩惱後的寂靜）。
三、 心路過程（Citta-vīthi）
在南傳體系中，心法不是一個固定不變的「靈魂」，而是依條件連續生起的「心識流（Citta-santāna）」。
當外境（色、聲、香、味、觸、法）與感官（眼、耳、鼻、舌、身、意）接觸時，會引發一連串依固定順序生滅的心識，稱為心路過程：
1. 有分心（Bhavaṅga）：生命維持流轉的底層心識狀態（類似無意識/潛意識狀態）。
2. 轉向心：注意到新目標。
3. 感官識/領受/推度/確定：接收並辨識目標。
4. 速速心（Javana）：通常連續生起7個剎那，在此階段造下善或不善的業（Kamma）。
5. 彼所緣心：領受餘韻，隨後落入有分心。
Theravāda Buddhist Mind Theory (AI Reference)
In Theravāda Buddhism—especially in the Abhidhammasystem (the Abhidhamma Piṭaka), and particularly in the Abhidhammattha Saṅgaha—all phenomena are classified into four ultimate realities (Paramattha):
consciousness (citta), mental factors (cetasika), matter (rūpa), and Nibbāna.
Among these, citta (mind) refers to the basic awareness that knows an object—the function of knowing.
1. Core Definition and Features of Mind (Citta)
One in nature, many in types:
From the ultimate perspective, there is only one kind of mind: the ability to know an object.
However, depending on associated mental factors, planes of existence (sense-sphere, form, formless, supramundane), and moral quality (wholesome, unwholesome, result, functional), it can be classified into 89 types of consciousness (basic system) or 121 types(detailed system).
Arising and passing away rapidly:
Mind arises and disappears extremely quickly—countless times in a moment.
Each moment has three phases: arising (uppāda), presence (ṭhiti), and dissolution (bhaṅga).
Always with mental factors:
Mind never arises alone. Each moment of consciousness is accompanied by mental factors (such as contact, feeling, perception, life faculty, etc.).
Mind is like a leader, while mental factors are the specific activities or qualities.
2. The 89 Types of Consciousness
In the Theravāda Abhidhamma, the 89 types of mind are grouped as follows:
(1) Sense-Sphere Consciousness (45 types)
• Unwholesome (12): rooted in greed (8), hatred (2), and delusion (2).
• Rootless (18): not associated with wholesome or unwholesome roots, including sense-consciousness (seeing, hearing, etc.), receiving, investigating, determining, mind-door adverting, and smiling consciousness.
• Beautiful (24): wholesome (8), resultant (8), and functional (8) consciousness in the sense sphere.
(2) Form-Sphere Consciousness (15 types)
Related to meditative absorption (jhāna) in the form realm:
• Wholesome (5)
• Resultant (5)
• Functional (5)
(3) Formless-Sphere Consciousness (12 types)
Related to the four formless attainments:
• Infinite space
• Infinite consciousness
• Nothingness
• Neither-perception-nor-non-perception
Each has:
• Wholesome (4)
• Resultant (4)
• Functional (4)
(4) Supramundane Consciousness (8 types, or 40 in expanded form)
These transcend the three realms and take Nibbāna as their object:
• Path consciousness (4): stream-entry, once-returner, non-returner, arahant path (cutting off defilements).
• Fruition consciousness (4): the peaceful experience after defilements are removed.
3. The Process of Mind (Citta-vīthi)
In Theravāda thought, mind is not a permanent “soul,” but a continuous flow of mental events (citta-stream).
When an external object (form, sound, smell, taste, touch, or mental object) meets a sense organ (eye, ear, nose, tongue, body, or mind), a sequence of mental events arises in a fixed order. This is called the process of mind:
1. Bhavaṅga (life-continuum): the underlying passive flow of mind, similar to a background or subconscious state.
2. Adverting consciousness: turning attention toward a new object.
3. Sense processing stages: receiving, investigating, and determining the object.
4. Javana (impulsion): usually 7 rapid moments where wholesome or unwholesome karma is created.
5. Registration (tadārammaṇa): briefly holding the object, then returning to bhavaṅga.
This system explains the mind not as a fixed entity, but as a dynamic, conditioned process that arises and ceases moment by moment.
