낙수 (불교)

낙수(樂受, 산스크리트어: sukha-vedanā 수카 베다나-, 팔리어: sukhā-vedanā 수카- 웨-다나-, 영어: pleasant feeling)는 즐거운 느낌으로, 전통적인 표현으로는 적열(適悅)의 수(受)라 하는데, 대략적으로 말하자면, 마음(6식 또는 8식, 즉 심왕, 즉 심법)이 대상으로부터 즐거움을 느끼는 것이다. 다음의 분류 또는 체계에 속한다. 고수 · 낙수 · 불고불락수의 3수(三受) 중 하나이다. 모든 느낌을 신수 · 심수의 2수(二受)로 나눌 때, 여기서의 낙수는 신수(身受, 감각적 느낌, 신체적 느낌)에도 속하고 심수(心受, 정신적 느낌)에도 속한다. 고수 · 낙수 · 우수 · 희수 · 사수의 5수(五受) 중 하나이다. 모든 느낌을 신수 · 심수의 2수(二受)로 나눌 때, 여기서의 낙수는 신수(身受, 감각적 느낌, 신체적 느낌)에만 속한다. 3수 중 낙수를 신체적 즐거운 느낌과 정신적 즐거운 느낌으로 세분하여 각각 5수의 낙수(즐거운 느낌)와 희수(기쁜 느낌)가 된다. 또한 3수 중 고수를 신체적 괴로운 느낌과 정신적 괴로운 느낌으로 세분하여 각각 5수의 고수(괴로운 느낌)와 우수(슬픈 느낌)가 된다. 신체적으로 즐거운 느낌이란 촉각적 즐거움을 말한다. 예를 들어, 새로 산 부드러운 이불을 덮어 기분이 좋은 것을 말한다. 정신적으로 즐거운 느낌이란, 예를 들어, 사랑하는 사람을 만나 그를 보자 마음이 기쁜 것을 말한다. 세친의 《대승오온론》에 따르면, 낙수(즐거운 느낌)의 정의는 어떤 대상과 헤어질 때 다시 만나고 싶어하는 느낌이다.

(2) Feeling (vedanā): Feeling is the mental factor that feels the object: it is the affective mode in which the object is experienced. The Pāḷi word vedanā does not signify “emotion” (which appears to be a complex phenomenon involving a variety of concomitant mental factors), but the bare affective quality of an experience, which may be either pleasant (sukhā-vedanā), unpleasant (dukkhā-vedanā), or neutral (adukkha-masukhā-vedanā). Feeling is said to have the characteristic of being felt (vedayita). Its function is experiencing, or its function is to enjoy the desirable aspect of the object. Its manifestation is the relishing of the associated mental factors. Its proximate cause is tranquility.49 Whereas the other mental factors experience the object only derivatively, feeling experiences it directly and fully. In this respect, the other factors are compared to a cook who prepares a dish for a king and only samples the food while preparing it, while feeling is compared to the king who enjoys the meal as much as he likes. 49 So say the Commentaries. But it seems that tranquility as proximate cause applies solely to the pleasant feeling when developing concentration. A more general proximate cause for feeling would be contact, in accordance with the principle “with contact as condition, feeling comes to be” (phassapaccayā vedanā). In fact, the entire treatment of feeling here is limited to a particular kind of feeling. For a fuller treatment of feeling in all its variety, see Chapter 3, §§2—4, and Guide.

Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.100. Three kinds of feeling: Feeling may be analyzed as either threefold or fivefold. When it is analyzed simply in terms of its attractive quality, it is threefold: pleasant, painful, and neither pleasant nor painful. In this threefold classification, pleasant feeling includes both bodily pleasure and mental pleasure, or joy, and painful feeling includes both bodily pain and mental pain, or displeasure. Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. pp.100-101. Feeling is analyzed as fivefold: When feeling is analyzed by way of the governing faculty (indriya), it becomes fivefold. These five types of feelings are called faculties because they exercise lordship (indra), or control, over their associated states with respect to the affective mode of experiencing the object. When the fivefold analysis of feeling is considered, the pleasant feeling of the threefold scheme becomes divided into pleasure and joy, the former bodily and the latter mental; and neither-pleasant-nor-painful feeling becomes identified with equanimity, or neutral feeling. In the Suttas, the Buddha sometimes also speaks of feeling as twofold, pleasure (sukha) and pain (dukkha). This is a loose or metaphorical method of analysis, arrived at by merging the blameless neutral feeling in pleasure and the blameworthy neutral feeling in pain. The Buddha further declares that whatever is felt is included in suffering (yaṁ kiñci vedayitaṁ taṁ dukkhasmiṁ [cf. Saṁyutta Nikāya 36:11/iv, 216]). In this statement, the word dukkha does not bear the narrow meaning of “painful feeling,” but the broader meaning of “the suffering inherent in all conditional things (sabbe saṁkhārā) by reason of their impermanence (anicca).” Pleasure (sukha): Pleasure has the characteristic of experiencing a desirable tangible object, the function of intensifying associated states, and manifestation as bodily enjoyment. Its proximate cause is the body faculty. Pain (dukkha): Pain has the characteristic of experiencing an undesirable tangible object, the function of withering associated states, and manifestation as bodily affliction. Its proximate cause is also the body faculty. Joy (somanassa): Joy has the characteristic of experiencing a desirable object, the function of partaking of the desirable aspect of the object, and manifestation as mental enjoyment. Its proximate cause is tranquility.69 Displeasure (domanassa): Displeasure has the characteristic of experiencing an undesirable object, the function of partaking of the undesirable aspect of the object, and manifestation as mental affliction. Its proximate cause is the heart-base.70 Equanimity (upekkhā): Equanimity has the characteristic of being felt as neutral, the function of neither intensifying nor withering associated states, and manifestation as peacefulness. Its proximate cause is consciousness without zest.71 69 Tranquility (passaddhi), it seems, is the proximate cause only for joyful feeling that arises in meditative development. 70 On the heart-base, see below, §20. 71 These definitions of the five feelings are found at Visuddhimagga XIV, 128. Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. pp.35~36. Wholesome-resultant rootless consciousness (kusalavipāka-ahetukacittāni): The eight types of consciousness in this category are results of wholesome kamma. In the designation of the previous class, the word ahetuka, “rootless,” was not included because all unwholesome-resultants are rootless; there are no unwholesome-resultants that are accompanied by roots. However, as will be seen later, wholesome-resultants can be accompanied by roots, namely, by beautiful roots that are karmically indeterminate (abyākata). To distinguish the wholesome-resultants that are rootless from those with roots, the word ahetuka is included in their class designation. Seven of these types of consciousness correspond to the unwholesome-resultants. But, whereas the unwholesome-resultants arise in regard to an undesirable object, the wholesome-resultants arise in regard to an object that is desirable (iṭṭha) or extremely desirable (ati-iṭṭha). The first four sense consciousnesses here, like their counterparts, are associated with equanimity, that is, neutral feeling; but since the impact of the object on the body is strong, the feeling associated with wholesome-resultant body-consciousness is that of bodily pleasure (sukha). The rootless wholesome-resultants include one type of consciousness without a counterpart among the unwholesome-resultants. This is the investigating consciousness accompanied by joy (somanassa). Whereas the investigating consciousness resulting from unwholesome kamma is always accompanied by neutral feeling, that resulting from wholesome kamma is twofold: one accompanied by neutral feeling arisen in regard to a moderately desirable object, and one accompanied by joy, which arises when the object is especially desirable. Thus, there are eight types of consciousness in this class, in contrast to the seven types found in the former class. (한국어) 각묵스님 옮김(2015) 《디가 니까야》 제2권 제22경 〈대념처경〉 초기불전연구원. pp.510~511.

Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.37~38. Five-sense-door adverting consciousness (pañcadvārāvajjanacitta): When an external sense object impinges on one of the five physical sense organs, before the appropriate sense consciousness can arise — for example, eye-consciousness seeing a form —, another consciousness must have arisen first. This consciousness is the fivesense- door adverting consciousness (pañcadvārāvajjanacitta), which has the function of adverting (āvajjana)31 to whatever object is presenting itself at one of the five sense doors (dvāra). This consciousness does not see, hear, smell, taste, or touch the object. It simply turns to the object, thereby enabling the sense consciousness to arise in immediate succession.32 31 This is the turning of the mind towards an object. Āvajjana forms the first stage in the process of consciousness. When an object of the five physical senses is involved, it is called “five-sense-door adverting consciousness” (pañcadvārāvajjanacitta); in the case of a mental object, “mind-door adverting consciousness” (manodvārāvajjanacitta). Cf, Nyanatiloka, Buddhist Dictionary: Manual of Buddhist Terms and Doctrines (fourth revised edition [1980]), pp. 30—31. 32 A single unit of sense perception (for example, visual consciousness), being conditioned through a sense organ and its corresponding object, forms in reality an extremely complex process, in which all the single phases of consciousness follow one another in rapid succession, performing their respective functions, for example: “As soon as a visible object has entered the range of vision, it acts on the sensitive eye-organ (cakkhu-pasāda), and, conditioned thereby, an excitation of the subconscious stream (bhavanga-sota) takes place. “As soon, however, as subconsciousness is broken off, the functional mind element, grasping the object and breaking through the subconscious stream, performs the function of ‘adverting’ (āvajjana) the mind towards the object. “Immediately thereupon, there arises at the eye-door, and based upon the sensitive eye-organ, the eye-consciousness, while performing the function of ‘seeing’ (dassana)… “Immediately thereafter, there arises the mind-element, performing the function of ‘receiving’ (sampaṭicchana) the object of that consciousness… “Immediately thereafter, there arises…the mind-consciousness element, while ‘investigating’ (santīraṇa) the object received by the mind-element… “Immediately thereafter, there arises the functional, rootless mind-consciousness-element, accompanied by indifference, while performing the function of ‘determining’ (votthapana) the object… “Now, if the object is large, then immediately afterwards there flash forth six or seven ‘impulsive moments’ (javana-citta), constituted by one of the eight wholesome (kusala) or twelve unwholesome (akusala) or nine functional (kiriya or kriyā) classes of consciousness. “Now, if, at the end of the impulsive moments, the object at the five-sense doors is very large and at the mind-door clear, then there arises, once or twice, one of the eight root-accompanied kamma-resultant classes of consciousness of the sense-sphere, or one of the three rootless kamma-resultant mindconsciousness- elements… Because this consciousness, after the vanishing of the impulsive moments, possesses the faculty continuing with the object of the subconsciousness, taking the object of the subconsciousness as its own object, thereby, it is called ‘registering’ (tadārammaṇa, literally, ‘that object’ or ‘having that as object’).” (Visuddhimagga XIV, 115ff.) If, however, the sense-object is weak, then it reaches merely the stage of “impulsion” (javana), or of “determining” (votthapana); if very weak, only an excitation of the subconsciousness takes place. The process of the inner, or mind, consciousness, that is, without participation of the five physical senses, is as follows: in the case that the mind-object entering the mind-door is distinct, then it passes through the stages of “adverting at the mind-door” (manodvārāvajjana), “the impulsive stage,” and “the registering stage,” before finally sinking into the subconscious stream.

IMMORAL RESULTANT CONSCIOUSNESS (Akusala Vipāka Citta) The seven akusala vipāka cittas are given the following symbols and names. cakkhu ghāna kāya santī — — — — ^ — — sota jivhā sampa 1 Upekkhā-sahagataṁ cakkhuviññāṇaṁ  eye-consciousness accompanied by neutral feeling. 2 Upekkhā-sahagataṁ sotaviññāṇaṁ  ear-consciousness accompanied by neutral feeling. 3 Upekkhā-sahagataṁ ghānaviññāṇaṁ  nose-consciousness accompanied by neutral feeling. 4 Upekkhā-sahagataṁ jivhāviññāṇaṁ  tongue-consciousness accompanied by neutral feeling. 5 Dukkha-sahagataṁ kāyaviññāṇaṁ  body-consciousness accompanied by painful feeling. 6 Upekkhā-sahagataṁ sampaṭicchana-cittaṁ  receiving consciousness accompanied by neutral feeling. 7 Upekkhā-sahagataṁ santīraṇa-cittaṁ  investigating-consciousness accompanied by indifference. Of the seven cittas mentioned above, the first five are known as pañca-viññāna, i.e., five cittas that are conscious of the five senses. The last two, i.e., sampaṭicchana-citta and santīraṇa-citta, represent two connecting stages in the process of cognition (awareness of an object). For example, when a visible object appears in the eye, a series of consciousness has to arise and perish in order to see the object. First pañca-dvārāvajjana (five-door directing consciousness) directs the consciousness stream towards the object. Then cakkhu-viññāṇa (eye consciousness) sees the object and transmits it to the next consciousness. Then sampaṭicchana (receiving consciousness) receives the sense object. Then santīraṇa (investigating consciousness) investigates the sense object. Then mano-dvārāvajjana (mind-door directing consciousness) determines the sense object whether it is good or bad. We are aware of the sense object roughly at this stage. Similarly, when an audible voice strikes the eardrum, a series of consciousness, i.e., pañca-dvārāvajjana, sotaviññāṇa, sampaṭichana, santīraṇa, mano-dvārāvajjana, etc., has to arise and perish before we can hear the voice. Thus sampaṭicchana-citta, santīraṇa citta together with pañca dvārāvajjana citta and mano-dvārāvajjana citta are essential for cognition of the senses at the five sense-doors (eye, ear, nose, tongue and body). Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.35. Accompanied by joy (somanassasahagata): The word somanassa, “joy,” is derived from su- = “pleasant” + manas- = “mind;” thus, it means, literally, a pleasant mental state. Somanassa is a type of feeling, specifically, pleasant mental feeling. All consciousness is accompanied by some feeling, which may be physical or mental, pleasant, painful, or neutral. Somanassa is a feeling that is mental rather than physical (bodily), and pleasant rather than painful or neutral. This feeling “accompanies” (sahagata) this type of consciousness in that it is inextricably blended with it, just as when the waters of two rivers meet, they blend together and cannot be distinguished. The Abhidhamma describes four cittas rooted in greed (lobha) and accompanied by a joyful mental feeling (somanassa). The other four cittas in this class are accompanied by equanimity (upekkhāsahagata). The word upekkhā is often used in the Pāḷi texts to signify the lofty spiritual quality of equanimity, or impartiality, the state of mind that cannot be swayed by biases and preferences. Here, however, the word is used simply to mean neutral feeling, a mental feeling that leans neither towards gladness nor sadness. In contrast to pleasant and painful feelings, which experience an object in diametrically opposed ways, upekkhā experiences the object in a neutral manner. Thus, upekkhā, or “equanimous feeling”, is also called “adukkhamasukhā vedanā,” “neither-painful- nor-pleasant feeling.” Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.100. Analysis of feeling: As we have seen, feeling (vedanā) is a universal mental factor, the cetasika with the function of experiencing the “flavor” of the object. Since some sort of feeling accompanies every citta, feeling serves as an important variable in terms of which consciousness can be classified. In this section, the author’s main concern is to classify the totality of cittas by way of their concomitant feeling. Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.31. Accompanied by equanimity (upekkhāsahagata): Even if a desirable object is present when a delusion-rooted consciousness arises, it is not experienced as desirable and thus pleasant mental feeling (somanassa) does not arise. Similarly, an undesirable object is not experienced as such, and thus unpleasant mental feeling (domanassa) does not arise. Moreover, when the mind is obsessed by doubt (vicikicchā) or restlessness (uddhacca), it is not capable of forming a determinate positive or negative evaluation of the object, and thus cannot be associated with either pleasant or painful feeling. For these reasons, the feeling that accompanies these two cittas is neutral, the feeling of equanimity (upekkhā).
