Yoga (philosophy)
Yoga philosophy is one of the six major orthodox schools of Hinduism. Ancient, medieval and most modern literature often refers to the Yoga school of Hinduism simply as Yoga. It is closely related to the Samkhya school of Hinduism. The Yoga school's systematic studies to better oneself physically, mentally and spiritually has influenced all other schools of Indian philosophy. The Yoga Sutras of Patanjali is a key text of the Yoga school of Hinduism.
The epistemology of the Yoga school of Hinduism, like the Sāmkhya school, relies on three of six Pramanas as the means of gaining reliable knowledge. These include Pratyakṣa, Anumāṇa and Sabda. The metaphysics of Yoga is built on the same dualist foundation as the Samkhya school. The universe is conceptualized as composed of two realities in the Samhkya-Yoga schools: Puruṣa and prakriti. Jiva is considered as a state in which puruṣa is bonded to prakriti in some form, in various permutations and combinations of various elements, senses, feelings, activity and mind. During the state of imbalance or ignorance, one or more constituents overwhelm the others, creating a form of bondage. The end of this bondage is called liberation, or moksha, by both the Yoga and Samkhya schools of Hinduism. The ethical theory of the Yoga school is based on Yamas and Niyama, as well as elements of the Guṇa theory of Samkhya.
The Yoga school of Hinduism differs from the closely related non-theistic/atheistic Samkhya school by incorporating the concept of a "personal, yet essentially inactive, deity" or "personal god". While the Samkhya school suggests that jnana is a sufficient means to moksha, the Yoga school suggests that systematic techniques and practice, or personal experimentation, combined with Samkhya's approach to knowledge, is the path to moksha. Yoga shares several central ideas with the Advaita Vedanta school of Hinduism, with the difference that Yoga philosophy is a form of experimental mysticism, while Advaita Vedanta is a form of monistic personalism. Advaita Vedanta, and other schools of Hinduism, accept, adopt and build upon many of the teachings and techniques of Yoga.
History
The origins of the Yoga school of Hinduism are unclear. Some of its earliest discussions are found in 1st millennium BCE Indian texts such as the Katha Upanishad, the Shvetashvatara Upanishad and the Maitri Upanishad.The root of "Yoga" is found in hymn 5.81.1 of the Rig Veda, a dedication to rising Sun-god in the morning, interpreted as "yoke" or "yogically control".
The Rig Veda, however, does not describe Yoga philosophy with the same meaning or context as in medieval or modern times. Early references to practices that later became part of Yoga school of Hinduism, are made in Brihadaranyaka Upanishad, the oldest Upanishad. Gavin Flood translates it as, "...having become calm and concentrated, one perceives the self, within oneself." The practice of pranayama is mentioned in hymn 1.5.23 of Brihadaranyaka Upanishad, and the practice of pratyahara is mentioned in hymn 8.15 of Chandogya Upanishad.
The Katha Upanishad, dated to be from about the middle of the 1st millennium BCE, in verses 2.6.6 through 2.6.13 recommends a path to Self-knowledge, and calls this path Yoga.
The Yoga school of Hinduism is mentioned in foundational texts of other orthodox schools such as the Vaisesikha Sutras, Nyaya Sutras and Brahma Sutras, which suggests that the Yoga philosophy was in vogue in the 1st millennium BCE. It influenced and was influenced by other schools and Indian philosophies. There are, for example, numerous parallels in the concepts in the Samkhya school of Hinduism, Yoga and the Abhidharma schools of thought, particularly from the 2nd century BCE to the 1st century AD, notes Larson. Patanjali's Yoga Sutras may be a synthesis of these three traditions. From the Samkhya school of Hinduism, the Yoga Sutras adopt the "reflective discernment" of prakrti and purusa, its metaphysical rationalism, as well its three epistemic methods to gaining reliable knowledge. From Abhidharma Buddhism's idea of nirodhasamadhi, suggests Larson, the Yoga Sutras adopt the pursuit of an altered state of awareness, but unlike Buddhism, which believes that there is neither self nor soul, Yoga is physicalist and realist like Samkhya in believing that each individual has a self and soul. The third concept that the Yoga Sutras synthesize into its philosophy is the ancient ascetic traditions of isolation, meditation and introspection.
The systematic collection of ideas of the Yoga school of Hinduism is found in the Yoga Sutras of Patanjali. After its circulation in the first half of the 1st millennium CE, many Indian scholars reviewed it, then published their Bhāṣya on it, which together form a canon of texts called the Pātañjalayogaśāstra.
Six darsanas
The Yoga school of Hinduism has been included as one of the six orthodox schools in medieval era Indian texts. The other schools are Samkhya, Nyaya, Vaisheshika, Mimamsa and Vedanta.Philosophy
The Yoga school of Hindu philosophy is most closely related to the Samkhya school. In both, the foundational concepts include two realities: Purusha and Prakriti. The Purusha is defined as that reality which is pure consciousness and is devoid of thoughts or qualities. The Prakriti is the empirical, phenomenal reality which includes matter and also mind, sensory organs and the sense of identity. A living being is held in both schools to be the union of matter and mind. The Yoga school differs from the Samkhya school in its views on the ontology of Purusha, on axiology and on soteriology.Epistemology
Yoga school, like Samkhya school, considers Pratyakṣa or Dṛṣṭam, Anumāna, and Śabda or Āptavacana to be the only valid means of knowledge or Pramana. Unlike few other schools of Hinduism such as Advaita Vedanta, Yoga did not adopt the following three Pramanas: Upamāṇa, Arthāpatti or Anupalabdi.- Pratyakṣa means perception. It is of two types in Hindu texts: external and internal. External perception is described as that arising from the interaction of five senses and worldly objects, while internal perception is described by this school as that of inner sense, the mind. The ancient and medieval Indian texts identify four requirements for correct perception: Indriyarthasannikarsa, Avyapadesya, Avyabhicara and Vyavasayatmaka. Some ancient scholars proposed "unusual perception" as pramana and called it internal perception, a proposal contested by other Indian scholars. The internal perception concepts included pratibha, samanyalaksanapratyaksa, and jnanalaksanapratyaksa. Further, some schools of Hinduism considered and refined rules of accepting uncertain knowledge from Pratyakṣa-pranama, so as to contrast nirnaya from anadhyavasaya.
- Anumāṇa means inference. It is described as reaching a new conclusion and truth from one or more observations and previous truths by applying reason. Observing smoke and inferring fire is an example of Anumana. In all except one Hindu philosophies, this is a valid and useful means to knowledge. The method of inference is explained by Indian texts as consisting of three parts: pratijna, hetu, and drshtanta. The hypothesis must further be broken down into two parts, state the ancient Indian scholars: sadhya and paksha. The inference is conditionally true if sapaksha are present, and if vipaksha are absent. For rigor, the Indian philosophies also state further epistemic steps. For example, they demand Vyapti – the requirement that the hetu must necessarily and separately account for the inference in "all" cases, in both sapaksha and vipaksha. A conditionally proven hypothesis is called a nigamana.
- Śabda means relying on word, testimony of past or present reliable experts. Hiriyanna explains Sabda-pramana as a concept which means reliable expert testimony. The schools of Hinduism which consider it epistemically valid suggest that a human being needs to know numerous facts, and with the limited time and energy available, he can learn only a fraction of those facts and truths directly. He must cooperate with others to rapidly acquire and share knowledge and thereby enrich each other's lives. This means of gaining proper knowledge is either spoken or written, but through Sabda. The reliability of the source is important, and legitimate knowledge can only come from the Sabda of reliable sources. The disagreement between the schools of Hinduism has been on how to establish reliability. Some schools, such as Carvaka, state that this is never possible, and therefore Sabda is not a proper pramana. Other schools debate means to establish reliability.
Metaphysics
The Samkhya-Yoga system espouses dualism between consciousness and matter by postulating two "irreducible, innate and independent realities: Purusha and Prakriti. While the Prakriti is a single entity, the Samkhya-Yoga schools admit a plurality of the Puruṣas in this world. Unintelligent, unmanifest, uncaused, ever-active, imperceptible and eternal Prakriti is alone the final source of the world of objects. The Puruṣa is considered as the conscious principle, a passive enjoyer and the Prakriti is the enjoyed. Samkhya-Yoga believes that the Puruṣa cannot be regarded as the source of inanimate world, because an intelligent principle cannot transform itself into the unconscious world. This metaphysics is a pluralistic spiritualism, a form of realism built on the foundation of dualism.
Yoga school of Hinduism adopts the theory of Guṇa from Samkhya. Guṇas theory states that three gunas are present in different proportions in all beings, and these three are sattva guna, rajas guna, and tamas guna. These three are present in every being but in different proportions, and the fundamental nature and psychological dispositions of beings is a consequence of the relative proportion of these three gunas. When sattva guna predominates an individual, the qualities of lucidity, wisdom, constructiveness, harmonious, and peacefulness manifest themselves; when rajas is predominant, attachment, craving, passion-driven activity and restlessness manifest; and when tamas predominates in an individual, ignorance, delusion, destructive behavior, lethargy, and suffering manifests. The guṇas theory underpins the philosophy of mind in Yoga school of Hinduism.
The early scholars of Yoga philosophy, posit that the Puruṣa by its nature is sattva, while Prakriti by its nature is tamas. They further posit that individuals at birth have buddhi. As life progresses and churns this buddhi, it creates asmita or ahamkara. When ego in turn is churned by life, manas is produced. Together, buddhi, ahamkara and manas interact and constitute citta in Yoga school of Hinduism. Unrestrained modification of citta causes suffering. A way of life that empowers one to become ever more aware of one's consciousness and spirituality innate in buddhi, is the path to one's highest potential and a more serene, content, liberated life. Patanjali's Yoga sutra begins, in verse 2 of Book 1, by defining Yoga as "restraining the Citta from Vrittis."
Axiology
Axiology in the texts of Yoga school of Hindu philosophy include both a theory of values through the observances of positive values and avoidance of negative, as well as an aesthetic theory on bliss from intrinsic and extrinsic perspectives. The values to be observed are called Niyamas, while those to be avoided are referred in the Yamas in Yoga philosophy.Over sixty different ancient and medieval era texts of Yoga philosophy discuss Yamas and Niyamas. The specific theory and list of values varies between the texts, however, Ahimsa, Satya, Asteya, Svādhyāya, Kșhamā, and Dayā are among the predominantly discussed ethical concepts by majority of these texts.
The five yamas listed by Patañjali in Yogasūtra 2.30 are:
- Ahiṃsā : Nonviolence, non-harming other living beings
- Satya : truthfulness, non-falsehood
- Asteya : non-stealing
- Brahmacarya : celibacy, non-cheating on one's partner
- Aparigraha : non-avarice, non-possessiveness
The Niyamas part of theory of values in the Yoga school include virtuous habits, behaviors and observances. The Yogasutra lists the niyamas as:
- Śauca: purity, clearness of mind, speech and body
- Santoṣa: contentment, acceptance of others, acceptance of one's circumstances as they are in order to get past or change them, optimism for self
- Tapas: persistence, perseverance, austerity
- Svādhyāya: study of Vedas, study of self, self-reflection, introspection of self's thoughts, speeches and actions
- Īśvarapraṇidhāna: contemplation of the Ishvara
Soteriology
Yoga school of Hinduism holds that ignorance is the cause of suffering and saṁsāra. Liberation, like many other schools, is removal of ignorance, which is achieved through discriminative discernment, knowledge and self-awareness. The Yoga Sūtras is Yoga school's treatise on how to accomplish this. Samādhi is the state where ecstatic awareness develops, state Yoga scholars, and this is how one starts the process of becoming aware of Purusa and true Self. It further claims that this awareness is eternal, and once this awareness is achieved, a person cannot ever cease being aware; this is moksha, the soteriological goal in Hinduism.Book 3 of Patanjali's Yogasutra is dedicated to soteriological aspects of yoga philosophy. Patanjali begins by stating that all limbs of yoga are necessary foundation to reaching the state of self-awareness, freedom and liberation. He refers to the three last limbs of yoga as sanyama, in verses III.4 to III.5, and calls it the technology for "discerning principle" and mastery of citta and self-knowledge. In verse III.12, the Yogasutras state that this discerning principle then empowers one to perfect sant and udita in one's mind and spirit, through intentness. This leads to one's ability to discern the difference between sabda, artha and pratyaya, and this ability empowers one to compassionately comprehend the cry/speech of all living beings. Once a yogi reaches this state of sanyama, it leads to unusual powers, intuition, self-knowledge, freedoms and kaivalya, the soteriological goal of the yogi.
The benefits of Yoga philosophy of Hinduism is then summarized in verses III.46 to III.55 of Yogasutras, stating that the first 5 limbs leads to bodily perfections such as beauty, loveliness, strength and toughness; while the last 3 limbs through sanyama leads to mind and psychological perfections of perceptiveness, one's nature, mastery over egoism, discriminative knowledge of purity, self and soul. This knowledge once reached is irreversible, states Yogasutra's Book IV.
God in Yoga school of Hinduism
Yoga philosophy allows the concept of God, unlike the closely related Samkhya school of Hinduism which is atheistic/non-theistic. Hindu scholars such as the 8th century Adi Sankara, as well many modern academic scholars describe the Yoga school as "Samkya school with God."The Yoga Sutras of Patanjali use the term Isvara in 11 verses: I.23 through I.29, II.1, II.2, II.32 and II.45. Ever since the Sutras' release, Hindu scholars have debated and commented on who or what is Isvara. These commentaries range from defining Isvara as a "personal god" to a "special self" to "anything that has spiritual significance to the individual". Whicher explains that while Patanjali's terse verses can be interpreted both as theistic or non-theistic, Patanjali's concept of Isvara in Yoga philosophy functions as a "transformative catalyst or guide for aiding the yogin on the path to spiritual emancipation".
Patanjali defines Isvara in verse 24 of Book 1, as "a special Self ",
Sanskrit:
– Yoga Sutras I.24
This sutra of Yoga philosophy of Hinduism adds the characteristics of Isvara as that special Self which is unaffected by one's obstacles/hardships, one's circumstances created by the past or by one's current actions, one's life fruits, and one's psychological dispositions or intentions.
Text sources
The most studied ancient and medieval era texts of the Yoga school of philosophy include those by Patanjali, Bhaskara, Haribhadra, Bhoja, and Hemachandra.References to the teachings of the Yoga school of Hinduism abound in ancient Indian texts of other orthodox schools of Hinduism, for example, verse 5.2.17 of Vaisheshika Sutra by Kanada, belonging to the Vaisheshika school of Hinduism and dated to be from the 1st millennium BCE, states
The Nyāya Sūtras by Akshapada variously dated to be from 4th to 2nd century BCE, and belonging to the Nyaya school of Hinduism, in chapter 4.2 discusses the importance of Yoga philosophy as follows,
The Brahma Sutras by Badarayana dated to somewhere between the 5th century BCE and the 2nd century BCE, belonging to the Vedanta school of Hinduism, in chapter 2 assumes the existence of a text called Yoga Smriti. Scholars contest whether this text was a precursor or the same as Patanjali's Yogasutra, but either premise is uncertain. The verses of Brahma Sutras assert that dualism of the prevailing Yoga philosophy is refuted, as the value of Yoga is as a means to realization of the Self, not in propositions about Self that is in conflict with the Vedic texts. Radhakrishnan translates the text as follows,
The Yoga Vasistha is a syncretic text on Yoga philosophy, variously dated to be from 6th- to 14th-century CE. It is structured as a dialogue between sage Vasistha of the Vedic era and the philosopher-king Rama of the Hindu epic Ramayana. The text synthesizes elements of Vedanta, Jainism, Yoga, Samkhya, Saiva Siddhanta and Mahayana Buddhism. Among other things, the text discusses Yoga philosophy in its various chapters. In section 6.1, Yoga Vasistha introduces Yoga as follows,
