Yoga (philosophy)

(1885–1966). The yoga posture shown is siddhasana.Yoga as a separate school of thought is mentioned in Indian texts from the end of the 1st millennium CE. A collection of practices and some 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 (notes and commentary) on it. The commentary by Vyasa may have been written by Patanjali himself, forming an integrated text called the Pātañjalayogaśāstra ("The Treatise on Yoga of Patañjali"). According to Bryant, There are numerous parallels in the concepts in the Samkhya school of Hinduism, Yoga and various strands of Buddhism, particularly from the 2nd century BCE to the 1st century AD, notes Larson. From the Samkhya school of Hinduism, the Yoga Sutras adopt the "reflective discernment" (adhyavasaya) of prakrti and purusa (dualism), its metaphysical rationalism, as well its three epistemic methods to gaining reliable knowledge. From the Buddhist practice of nirodhasamadhi, argues Larson, the Yoga Sutras adopt the pursuit of an altered state of awareness, but unlike Buddhism, which believes that there is no fixed self, Yoga is physicalist 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. == Metaphysics ==

Comparison to Samkhya Yoga-philosophy is Samkhya. In both, the foundational concepts include two realities: Purusha and Prakriti. The metaphysics of Yoga-Samkhya is a form of dualism. It considers consciousness and matter, self/soul and body as two different realities. 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 (bhokta) and the Prakriti is the enjoyed (bhogya). 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-philosophy adopts the theory of Guṇa from Samkhya. 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. == Soteriology ==

, Dhyana and Samadhi is Sanyama'' – the path to Moksha or Kaivalya in Yoga school. Yoga school of Hinduism holds that ignorance is the cause of suffering and saṁsāra. In verse III.12, the Yogasutras state that this discerning principle then empowers one to perfect sant (tranquility) and udita (reason) in one's mind and spirit, through intentness. This leads to one's ability to discern the difference between sabda (word), artha (meaning) and pratyaya (understanding), 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. 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 non-theistic. 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 (Sanskrit: ईश्वर) in verse 24 of Book 1, as "a special Self (पुरुषविशेष, puruṣa-viśeṣa)", – Yoga Sutras I.24 This sutra adds the characteristics of Isvara as that special Self which is unaffected (अपरामृष्ट, aparamrsta) by one's obstacles/hardships (क्लेश, klesha), one's circumstances created by the past or by one's current actions (कर्म, karma), one's life fruits (विपाक, vipâka), and one's psychological dispositions or intentions (आशय, ashaya). Preparatory ethical rules Preparatory ethical rules 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. • Ahiṃsā (अहिंसा): Nonviolence, non-harming other living beings • Satya (सत्य): truthfulness, non-falsehood Patanjali, in Book 2, explains how and why each of the above self restraints help in the personal growth of an individual. For example, in verse II.35, Patanjali states that the virtue of nonviolence and non-injury to others (Ahimsa) leads to the abandonment of enmity, a state that leads the yogi to the perfection of inner and outer amity with everyone, everything. Other texts of the Yoga school of Hinduism include Kṣamā (क्षमा, forgiveness), Dhṛti (धृति, fortitude, non-giving up in adversity), Dayā (दया, compassion), and Mitāhāra (मितहार, measured diet). 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 (see Sabda in epistemology section), study of self, self-reflection, introspection of self's thoughts, speeches and actions • Īśvarapraṇidhāna: contemplation of the Ishvara (God/Supreme Being, Brahman, True Self, Unchanging Reality) As with Yamas, Patanjali explains how and why each of the above Niyamas help in the personal growth of an individual. For example, in verse II.42, Patanjali states that the virtue of contentment and acceptance of others as they are (Santoṣa) leads to the state where inner sources of joy matter most, and the craving for external sources of pleasant ceases. Other texts of the Yoga school expanded the list of values under Niyamas, to include behaviors such as Āstika (आस्तिक, belief in personal God, faith in Self, conviction that there is knowledge in Vedas/Upanishads), Dāna (दान, charity, sharing with others), Hrī (ह्री, remorse and acceptance of one's past/mistakes/ignorance, modesty) Mati (मति, think and reflect, reconcile conflicting ideas) and Vrata (व्रत, resolutions and vows, fast, pious observances). == Epistemology ==

File:3 Pramana Epistemology Samkhya Yoga Hindu schools.svg|thumb|The Yoga school considers perception, inference and reliable testimony as three reliable means to knowledge. The ancient and medieval Indian texts identify four requirements for correct perception: 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 (intuition), samanyalaksanapratyaksa (a form of induction from perceived specifics to a universal), and jnanalaksanapratyaksa (a form of perception of prior processes and previous states of a 'topic of study' by observing its current state). Further, some schools of Hinduism considered and refined rules of accepting uncertain knowledge from Pratyakṣa-pranama, so as to contrast nirnaya (definite judgment, conclusion) from anadhyavasaya (indefinite judgment). • Anumāṇa (अनुमान) 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. this is a valid and useful means to knowledge. The method of inference is explained by Indian texts as consisting of three parts: pratijna (hypothesis), hetu (a reason), and drshtanta (examples). The hypothesis must further be broken down into two parts, state the ancient Indian scholars: sadhya (that idea which needs to be proven or disproven) and paksha (the object on which the sadhya is predicated). The inference is conditionally true if sapaksha (positive examples as evidence) are present, and if vipaksha (negative examples as counter-evidence) are absent. For rigor, the Indian philosophies also state further epistemic steps. For example, they demand Vyapti – the requirement that the hetu (reason) must necessarily and separately account for the inference in "all" cases, in both sapaksha and vipaksha. A conditionally proven hypothesis is called a nigamana (conclusion). • Śabda (शब्द) 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 neither spoken or written, but through Sabda (sound). == Text sources ==

The most studied ancient and medieval era texts of the Yoga school of philosophy include those by Patanjali, Bhaskara, Haribhadra (Jain scholar), 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, and belonging to the Nyaya school of Hinduism, in chapter 4.2 discusses the importance of Yoga as follows, {{Blockquote|We are instructed to practice meditation in such places as a forest, a cave or a sand-bank. Such possibilities [the opponent claims] may occur even in release. It is, we reply, not so, because knowledge must spring up only in a body already in the state of formation. And there is absence of a body in our release. For that purpose, there should be a purifying of our soul by abstinence from evil, and observance of certain virtues, as well as by following the spiritual injunctions gleaned from Yoga. To secure release [moksha], it is necessary to study and follow this treatise on knowledge [Yoga], as well as to hold discussions with those learned in that treatise. The Brahma Sutras by Badarayana, estimated to have been completed in its surviving form in approx. 400–450 CE, while the original version might be ancient and composed between 500 BCE and 200 BCE, 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, {{Blockquote|Yoga is the utter transcendence of the mind and is of two types. Self-knowledge is one type, another is the restraint of the life-force of self limitations and psychological conditioning. Yoga has come to mean only the latter, yet both the methods lead to the same result. To some, Self-knowledge through inquiry is difficult, to others Yoga is difficult. But my conviction is that the path of inquiry is easy for all, because Self-knowledge is the ever-present truth. I shall now describe to you the method of Yoga. == See also ==
