Guṇa

In Samkhya philosophy, a guṇa is one of three "attributes, tendencies, qualities": sattva, rajas and tamas. This category of guṇas has been widely adopted by various schools of Hinduism for categorizing behavior and natural phenomena. The three qualities are:

• Sattva is the guṇa of balance, harmony, goodness, purity, universal-ism, holism, construction, creativity, positivity, peacefulness, and virtue.[21]
• Rajas is the guṇa of passion, activity, neither good nor bad and sometimes either, self-centeredness, egoism, individualization, drivenness, movement, and dynamism.[5][22]
• Tamas is the guṇa of imbalance, disorder, chaos, anxiety, impurity, destruction, delusion, negativity, dullness or inactivity, apathy, inertia or lethargy, violence, viciousness, and ignorance.[22][23]

In Indian philosophy, these qualities are not considered present in an either-or fashion. Rather, everyone and everything has all three, only in different proportions and in different contexts.[4] The living being or substance is viewed as the net result of the joint effect of these three qualities.[4][5]

According to Samkya school, no one and nothing is either purely Sattvik or purely Rajasik or purely Tamasik.[5] One's nature and behavior constitute a complex interplay of all of all three guṇas, in varying degrees. In some, the conduct is Rajasik with significant influence of Sattvik guṇa; in some it is Rajasik with significant influence of Tamasik guṇa, and so on.[5]

The balance of Gunas of everything and everyone can change and does. However, change in one quality faces inertia from other two qualities in Indian worldview. Change needs internal or external influence or reinforcement, as knowledge and force to transform. The force to change comes from the Rajas guṇa, the Sattva guṇa empowers one towards harmonious and constructive change, while Tamas guṇa checks or retards the process.

In Indian mythology, Vishnu is envisioned with more Sattva, Brahma with more Rajas, and Shiva seen with all three Gunas.[20]

In Nyaya (Generality or common features) school of Hinduism, there is extensive debate on what Guna means, and whether quality is innate, subjective or describable. Early scholars of this school identified 17 qualities, which later scholars expanded to 24 guṇas. Different scholars of this school list the 24 differently; for example, Bhasarvajna disallows 6 of the 24 commonly accepted by the ancient scholars.[10] The most commonly accepted list is: color, taste, smell, touch, number, contact, disjunction, farness, nearness, dimension, separateness, knowledge, pleasure, frustration, desire, hatred, effort, weight, fluidity, viscosity, dispositional tendency, merit, demerit, and sound.[24]

Nyaya school considers quality as non-repeatable, a conceptual theme not found in Western philosophy where "quality" is presumed to be repeatable. It is also not found in some parallel schools of Hinduism. Repeatability means that the white in one object is same as white in other object, and white means the same thing. Nyaya scholars hold that "whiteness" is a guṇa of "white", but that is different from "whiteness" of an object or living being. To them, white has many hues and the "whiteness" is subjective.[24]

In Laksanavali, an ancient Indian text by Udayana, Guna is discussed with more nuance. For example, he writes, "quality of earth" is specific only if it meets three conditions: it occurs in earth, does not occur in anything that is not earthy, and be a distinctive quality that cannot be described as combination of other qualities.[25]

In Vaisheshika school of Hinduism, which is most related to Nyaya school, states that our awareness, understanding and judgments of any person and thing in the world is relational. All relations, holds this school of Hinduism, is dyadic between anuyogin (referend) and pratiyogin (referent).[26] Guna (quality) is considered one of the seven padārtha (category) of relations. The others are: inherence (samavaya), being (bhava), genus (samanya), species (vishesha), substance (dravya) and motion/action (karman). Unlike Vaisheshika, Nyaya considers inherence as subset of guṇa (quality).[26]

Gangesha, a Nyaya scholar, suggests a somewhat different theory, stating that our awareness is of two types – true and false. True awareness is produced when we seek to observe some excellence (guṇa) in its cause, while false awareness results from observing fault (dosha) in its cause. In other words, in Gangesha's perspective, the observer's state of mind and attitude affects relational awareness.[27]

Chapters 2, 3, 7, 13, 14, 17 and 18 of Bhagavad Gita discuss Guna.[28] Verse 17.2 refers to the three Guna – sattvic, rajasic and tamasic – as innate nature (psychology or personality of an individual).[29][30] Sattvic guṇa is one driven by what is pure, truth, compassionate, without craving, doing the right because it is right, positive and good. Tamasic guṇa is one driven by what is impure, dark, destructive, aimed to hurt another, contemptuous, negative and vicious. Rajasic guṇa is one that is ego-driven, out of personal passion, active, ostentatious, seeking the approval of others.[28][30]

In Chapters 17 and 18, Bhagavad Gita illustrates various items and actions by their three Guna. For example, three types of charity are discussed, and what makes charity Sattvic, Rajasic or Tamasic. Similarly, food, relationships, knowledge and actions are detailed in terms of the three Guna.[28] In Chapter 18, for example:[31]

नियतं सङ्गरहितमरागद्वेषतः कृतम् । अफलप्रेप्सुना कर्म यत्तत्सात्त्विकमुच्यते ॥२३॥
यत्तु कामेप्सुना कर्म साहंकारेण वा पुनः । क्रियते बहुलायासं तद्राजसमुदाहृतम् ॥२४॥
अनुबन्धं क्षयं हिंसामनपेक्ष्य च पौरुषम् । मोहादारभ्यते कर्म यत्तत्तामसमुच्यते ॥२५॥

Action that is virtuous, thought through, free from attachment, and without craving for results is considered Sattvic; Action that is driven purely by craving for pleasure, selfishness and much effort is Rajasic; Action that is undertaken because of delusion, disregarding consequences, without considering loss or injury to others or self, is called Tamasic.

— Bhagavad Gita, Chapter 18, verses 23–25 [31]

Similarly, knowledge that is attached to object of action, without concern for understanding the cause, without concern for purpose or significance, is Tamasic knowledge; knowledge that is segregated, that considers everything unconnected, individualistic and meaningless is Rajasic; knowledge that sees one being in all beings, that seeks the whole, a unity in diversity, and similarities in the divided components is Sattvic.[32]

Furthermore, in Chapter 2 of the Bhagavad Gita, Krishna advises Arjuna to transcend the three modes of existence and other forms of dualism.[33]

In the Sanskrit grammatical tradition (Vyakarana), guṇa is an ancient language innovation that strengthens vowel-stems, making them more visually palpable when written and more musically resonant when heard.[13] Dwight states that the use of guṇa makes the Sanskrit language more dynamical, bringing out into relief the idea expressed, given its complexity; in other words, the use of guṇa in Sanskrit adds depth and sophistication in its phonetic delivery as well as intellectual structure.[13] These innovations are not unique to Sanskrit, but also found in Greek, Latin, Italian and to some extent Russian.[44] Guna and other rules of language for Sanskrit are described by Pāṇini in his Ashtadhyayi.[45]

Guṇa refers to a set of normal-length vowels that are less reduced than the basic set (in modern terms, the zero grade), but more reduced than the vṛddhi vowels (in modern terms, the lengthened grade). As an example, ṛ, i, u are basic (zero-grade) vowels, with corresponding guṇa (full-grade) vowels ar, e, o and vṛddhi (lengthened-grade) vowels ār, ai, au. (This is more understandable once it is realized that, at an earlier stage of development, Sanskrit e and o were ai and au, and Sanskrit ai and au were āi and āu.) Guṇa corresponds to what is now termed the full grade in Indo-European ablaut. Another orthography and phonology concept related to Guṇa is Vṛddhi.[46]

In the terminology of Ayurveda (traditional medicine), guṇa can refer to one of twenty fundamental properties which any substance can exhibit, arranged in ten pairs of antonyms, viz. heavy/light, cold/hot, unctuous/dry, dull/sharp, stable/mobile, soft/hard, non-slimy/slimy, smooth/coarse, minute/gross, viscous/liquid.[47]

Guṇa is also a concept in Ayurvedic medicine, as a system to assess conditions and diets. For this reason Triguṇa and tridosha are considered to be related in the traditions of Ayurveda.
