'''고수'''(苦受, {{llang|sa|duḥkha-vedanā|두카 베다나-}}, {{llang|pi|dukkhā-vedanā|둑카- 웨-다나-}}, {{llang|en|unpleasant feeling}})<ref>Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.68.
<br/><b>(2) Feeling (<i>vedanā</i>):</b> Feeling is the mental factor that feels the object: it is the
affective mode in which the object is experienced. The Pāḷi word <i>vedanā</i> 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 (<i>sukhā-vedanā</i>), unpleasant (<i>dukkhā-vedanā</i>),
or neutral (<i>adukkha-masukhā-vedanā</i>). Feeling is said to have the characteristic of being felt (<i>vedayita</i>). 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.<sup>49</sup> 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.
<br/><sup>49</sup> 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” (<i>phassapaccayā vedanā</i>). 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.

신체적으로 괴로운 느낌이란 통증을 말한다. 예를 들어, 바늘에 찔리거나 병에 걸려 아픈 것을 말한다. 정신적으로 괴로운 느낌이란, 예를 들어, 사랑하는 사람이 여윈 모습을 보고 걱정이 되거나 마음이 아픈 것을 말한다.

[[세친]]의 《[[대승오온론]]》 등에 따르면, 고수(괴로운 느낌)의 정의는 어떤 대상을 만났을 때 헤어지고 싶어하는 느낌이다. 즉, 만나고 싶어하지 않는 느낌이다. 달리 말하여, 고수(괴로운 느낌)는 [[마음에 들지 않는]][不可意] 대상을 만났을 때 가지게 되는 느낌이다. 그리고 불교에 따르면, 마음에 드는 대상 또는 마음에 들지 않는 대상을 만나는 것은 [[인과 (불교)|인과법칙]] 즉 [[업]]과 업의 [[과보]]의 법칙 즉 [[연기법]]에 따른 것으로, 과거에 [[3업|몸과 말과 뜻]]으로 지은 [[불선]]한(해로운) 행위로 인해 불선한(해로운) 업이 쌓이고 이 업으로 인해 [[마음에 들지 않는]] 대상과 만나게 된다.<ref name="원인_없는_유익한_과보의_마음-Bodhi1">Bhikkhu Bodhi & Allan R.

<br/><b>Wholesome-resultant rootless consciousness (<i>kusalavipāka-ahetukacittāni</i>):</b>
<br/>The eight types of consciousness in this category are results of wholesome kamma. In the
designation of the previous class, the word <i>ahetuka</i>, “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
(<i>abyākata</i>). To distinguish the wholesome-resultants that are rootless from those with
roots, the word <i>ahetuka</i> is included in their class designation.
<br/>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 (<i>iṭṭha</i>) or extremely
desirable (<i>ati-iṭṭha</i>). 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 (<i>sukha</i>).
<br/>The rootless wholesome-resultants include one type of consciousness without a
counterpart among the unwholesome-resultants. This is the investigating consciousness
accompanied by joy (<i>somanassa</i>). Whereas the investigating consciousness resulting
from unwholesome kamma is always accompanied by neutral feeling, that resulting from
wholesome <i>kamma </i>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.

<br/><b>Five-sense-door adverting consciousness (<i>pañcadvārāvajjanacitta</i>):</b> 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 (<i>pañcadvārāvajjanacitta</i>), which has the function of
adverting (<i>āvajjana</i>)<sup>31</sup> to whatever object is presenting itself at one of the five sense doors
(<i>dvāra</i>). 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.<sup>32</sup>
<br/><sup>31</sup> 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” (<i>pañcadvārāvajjanacitta</i>); in the case of a mental object, “mind-door adverting
consciousness” (<i>manodvārāvajjanacitta</i>). Cf, Nyanatiloka, <i>Buddhist Dictionary: Manual of Buddhist
Terms and Doctrines</i> (fourth revised edition [1980]), pp. 30—31.
<br/><sup>32</sup> 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:
<br/>“As soon as a visible object has entered the range of vision, it acts on the sensitive eye-organ
(<i>cakkhu-pasāda</i>), and, conditioned thereby, an excitation of the subconscious stream (<i>bhavanga-sota</i>) takes
place.
<br/>“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’ (<i>āvajjana</i>) the
mind towards the object.
<br/>“Immediately thereupon, there arises at the eye-door, and based upon the sensitive eye-organ, the
eye-consciousness, while performing the function of ‘seeing’ (<i>dassana</i>)…
<br/>“Immediately thereafter, there arises the mind-element, performing the function of ‘receiving’
(<i>sampaṭicchana</i>) the object of that consciousness…
<br/>“Immediately thereafter, there arises…the mind-consciousness element, while ‘investigating’
(<i>santīraṇa</i>) the object received by the mind-element…
<br/>“Immediately thereafter, there arises the functional, rootless mind-consciousness-element,
accompanied by indifference, while performing the function of ‘determining’ (<i>votthapana</i>) the object…
<br/>“Now, if the object is large, then immediately afterwards there flash forth six or seven ‘impulsive
moments’ (<i>javana-citta</i>), constituted by one of the eight wholesome (<i>kusala</i>) or twelve unwholesome
(<i>akusala</i>) or nine functional (<i>kiriya</i> or <i>kriyā</i>) classes of consciousness.
<br/>“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 <i>kamma</i>-resultant
classes of consciousness of the sense-sphere, or one of the three rootless <i>kamma</i>-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’ (<i>tadārammaṇa</i>, literally, ‘that object’
or ‘having that as object’).” (<i>Visuddhimagga</i> XIV, 115ff.)
<br/>If, however, the sense-object is weak, then it reaches merely the stage of “impulsion” (<i>javana</i>), or
of “determining” (<i>votthapana</i>); if very weak, only an excitation of the subconsciousness takes place.
<br/>
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” (<i>manodvārāvajjana</i>), “the impulsive stage,” and “the
registering stage,” before finally sinking into the subconscious stream. Cf, Nyanatiloka, <i>Buddhist
Dictionary: Manual of Buddhist Terms and Doctrines</i> (fourth revised edition [1980]), pp. 227—228.

<br/>{{pad|1em}}receiving consciousness accompanied by neutral feeling.
<br/>7 Upekkhā-sahagataṁ santīraṇa-cittaṁ
<br/>{{pad|1em}}investigating-consciousness accompanied by indifference.
<br/>
<br/>Of the seven cittas mentioned above, the first five are known as
<i><b>pañca-viññāna</b></i>, i.e., five <i>cittas</i> that are conscious of the five senses.
The last two, i.e., <i>sampaṭicchana-citta</i> and <i>santīraṇa-citta</i>, represent
two connecting stages in the process of cognition (awareness of
an object).
<br/>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
<i>pañca-dvārāvajjana</i> (five-door directing consciousness) directs the consciousness
stream towards the object. Then <i>cakkhu-viññāṇa</i> (eye consciousness)
sees the object and transmits it to the next consciousness.
<br/>Then <i>sampaṭicchana</i> (receiving consciousness) receives the sense
object. Then <i>santīraṇa</i> (investigating consciousness) investigates the
sense object. Then <i>mano-dvārāvajjana</i> (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.
<br/>Similarly, when an audible voice strikes the eardrum, a series of
consciousness, i.e., <i>pañca-dvārāvajjana</i>, <i>sotaviññāṇa</i>, <i>sampaṭichana</i>,
<i>santīraṇa</i>, <i>mano-dvārāvajjana</i>, etc., has to arise and perish before we
can hear the voice.
<br/>Thus <i>sampaṭicchana-citta</i>, <i>santīraṇa citta</i> together with <i>pañca
dvārāvajjana citta</i> and <i>mano-dvārāvajjana citta</i> are essential for cognition
of the senses at the five sense-doors (eye, ear, nose, tongue and
body).

==신체적인 괴로움과 정신적인 괴로움==

불교에 따르면, 모든 마음은 반드시 [[수 (불교)|느낌]][受]을 [[동반한다]].(참고: [[변행심소]], [[대지법]])<ref name="somanassasahagata">Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.35.
<br/>'''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.”

<br/><b>Analysis of feeling:</b> As we have seen, feeling (<i>vedanā</i>) 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.

<br/><b>Three kinds of feeling:</b> 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.

3수의 고수를 5수의 고수와 우수로 세분한 이유는 다음과 같다. 과거의 업이 해로운(불선) 업일 때, [[마음에 들지 않는]] 대상 즉 [[괴로운]] 대상과 만나게 된다. 이 때 [[전5식]] 중 [[신식]]은 다른 네 가지 [[안식 (불교)|안식]]{{.cw}}[[이식]]{{.cw}}[[비식]]{{.cw}}[[설식]]이 [[평온]] 즉 [[괴롭지도 즐겁지도 않은 느낌]] 즉 [[사수 (불교)|사수]]와 [[함께하는]] 것과는 달리 신체적인 고통의 느낌과 [[함께한다]]. 즉 통증을 느낀다.(참고: [[해로운 과보의 마음]]) 말하자면, 눈(안근)의 통증이란 눈(안근)이 느끼는 통증이 아니라 몸(신근)이 느끼는 통증이다. 그렇기 때문에 괴로운 대상과 만났을 때 안식{{.cw}}이식{{.cw}}비식{{.cw}}설식과 함께하는 괴로움은 신체적인 것이 아니라 정신적인 것이다. 예를 들어, 만나기 싫은 사람을 보게 되어 괴로운 느낌(피하고 싶은 느낌)이 들었을 때, 봄(안식)은 신체적인 것 즉 감각적인 것이지만 이 봄(안식)과 함께 일어나는 괴로움은 정신적인 것이다. 즉, 고수가 아니라 우수이다. 전통적으로, 고수 즉 신체적인 괴로움을 '괴로움'({{llang|pi|dukkha|둑카}}, {{llang|en|pain}})이라고 이름하고 우수 즉 정신적인 괴로움을 '슬픔'({{llang|pi|domanassa|도-마낫사}}, {{llang|en|displeasure}})이라고 이름한다.<ref>Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. p.31.
<br/><b>Accompanied by equanimity (<i>upekkhāsahagata</i>):</b> Even if a desirable object is
present when a delusion-rooted consciousness arises, it is not experienced as desirable
and thus pleasant mental feeling (<i>somanassa</i>) does not arise. Similarly, an undesirable
object is not experienced as such, and thus unpleasant mental feeling (<i>domanassa</i>) does
not arise. Moreover, when the mind is obsessed by doubt (<i>vicikicchā</i>) or restlessness
(<i>uddhacca</i>), 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
(<i>upekkhā</i>).
</ref><ref>Bhikkhu Bodhi & Allan R. Bomhard (2007). 《A Comprehensive Manual of Abhidhamma》. Charleston Buddhist Fellowship. pp.100-101.
<br/><b>Feeling is analyzed as fivefold:</b> When feeling is analyzed by way of the
governing faculty (<i>indriya</i>), it becomes fivefold. These five types of feelings are called
faculties because they exercise lordship (<i>indra</i>), or control, over their associated states
with respect to the affective mode of experiencing the object.
<br/>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.
<br/>In the Suttas, the Buddha sometimes also speaks of feeling as twofold, pleasure
(<i>sukha</i>) and pain (<i>dukkha</i>). 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 <i>(yaṁ
kiñci vedayitaṁ taṁ dukkhasmiṁ</i> [cf. <i>Saṁyutta Nikāya</i> 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 (<i>sabbe saṁkhārā</i>) by reason
of their impermanence (<i>anicca</i>).”
<br/>Pleasure (<i>sukha</i>): 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.
<br/>Pain (<i>dukkha</i>): 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.
