Yoga (Sanskrit, Pāli: योग yóga) refers to traditional physical and mental disciplines originating in India.The word is associated with meditative practices in Buddhism and Hinduism. In Hinduism, it also refers to one of the six orthodox (āstika) schools of Hindu philosophy, and to the goal toward which that school directs its practices. In Jainism it refers to the sum total of all activities—mental, verbal and physical.
Major branches of yoga in Hindu philosophy include Raja Yoga, Karma Yoga, Jnana Yoga, Bhakti Yoga, and Hatha Yoga. Raja Yoga, compiled in the Yoga Sutras of Patanjali, and known simply as yoga in the context of Hindu philosophy, is part of the Samkhya tradition. Many other Hindu texts discuss aspects of yoga, including Upanishads, the Bhagavad Gita, the Hatha Yoga Pradipika, the Shiva Samhita and various Tantras.
The Sanskrit word yoga has many meanings, and is derived from the Sanskrit root yuj, meaning "to control", "to yoke" or "to unite". Translations include "joining", "uniting", "union", "conjunction", and "means". Outside India, the term yoga is typically associated with Hatha Yoga and its asanas (postures) or as a form of exercise. Someone who practices yoga or follows the yoga philosophy is called a Yogi.
Yoga Sutras of Patanjali
In Indian philosophy, Yoga is the name of one of the six orthodox philosophical schools. The Yoga philosophical system is closely allied with the Samkhya school. The Yoga school as expounded by the sage Patanjali accepts the Samkhya psychology and metaphysics, but is more theistic than the Samkhya, as evidenced by the addition of a divine entity to the Samkhya's twenty-five elements of reality. The parallels between Yoga and Samkhya were so close that Max Müller says that "the two philosophies were in popular parlance distinguished from each other as Samkhya with and Samkhya without a Lord...." The intimate relationship between Samkhya and Yoga is explained by Heinrich Zimmer:
These two are regarded in India as twins, the two aspects of a single discipline. Sāṅkhya provides a basic theoretical exposition of human nature, enumerating and defining its elements, analyzing their manner of co-operation in a state of bondage (bandha), and describing their state of disentanglement or separation in release (mokṣa), while Yoga treats specifically of the dynamics of the process for the disentanglement, and outlines practical techniques for the gaining of release, or 'isolation-integration' (kaivalya).
Patanjali is widely regarded as the founder of the formal Yoga philosophy. Patanjali's yoga is known as Raja yoga, which is a system for control of the mind. Patanjali defines the word "yoga" in his second sutra, which is the definitional sutra for his entire work:
योग: चित्त-वृत्ति निरोध:
( yogaś citta-vṛtti-nirodhaḥ )
This terse definition hinges on the meaning of three Sanskrit terms. I. K. Taimni translates it as "Yoga is the inhibition (nirodhaḥ) of the modifications (vṛtti) of the mind (citta)". The use of the word nirodhaḥ in the opening definition of yoga is an example of the important role that Buddhist technical terminology and concepts play in the Yoga Sutra; this role suggests that Patanjali was aware of Buddhist ideas and wove them into his system. Swami Vivekananda translates the sutra as "Yoga is restraining the mind-stuff (Citta) from taking various forms (Vrittis)."
Patanjali's writing also became the basis for a system referred to as "Ashtanga Yoga" ("Eight-Limbed Yoga"). This eight-limbed concept derived from the 29th Sutra of the 2nd book, and is a core characteristic of practically every Raja yoga variation taught today. The Eight Limbs are:
Yama (The five "abstentions"): non-violence, non-lying, non-covetousness, non-sensuality, and non-possessiveness.
Niyama (The five "observances"): purity, contentment, austerity, study, and surrender to god.
Asana: Literally means "seat", and in Patanjali's Sutras refers to the seated position used for meditation.
Pranayama ("Suspending Breath"): Prāna, breath, "āyāma", to restrain or stop. Also interpreted as control of the life force.
Pratyahara ("Abstraction"): Withdrawal of the sense organs from external objects.
Dharana ("Concentration"): Fixing the attention on a single object.
Dhyana ("Meditation"): Intense contemplation of the nature of the object of meditation.
Samādhi ("Liberation"): merging consciousness with the object of meditation.
In the view of this school, the highest attainment does not reveal the experienced diversity of the world to be illusion. The everyday world is real. Furthermore, the highest attainment is the event of one of many individual selves discovering itself; there is no single universal self shared by all persons.
Bhagavad Gita
The Bhagavad Gita ('Song of the Lord'), uses the term yoga extensively in a variety of ways. In addition to an entire chapter (ch. 6) dedicated to traditional yoga practice, including meditation, it introduces three prominent types of yoga:
Karma yoga: The yoga of action,
Bhakti yoga: The yoga of devotion,
Jnana yoga: The yoga of knowledge.
Madhusudana Sarasvati (b. circa 1490) divided the Gita into three sections, with the first six chapters dealing with Karma yoga, the middle six with Bhakti yoga, and the last six with Jnana (knowledge).Other commentators ascribe a different 'yoga' to each chapter, delineating eighteen different yogas.
Hatha Yoga
Hatha Yoga is a particular system of Yoga described by Yogi Swatmarama, compiler of the Hatha Yoga Pradipika in 15th century India. Hatha Yoga differs substantially from the Raja Yoga of Patanjali in that it focuses on shatkarma, the purification of the physical body as leading to the purification of the mind (ha), and prana, or vital energy (tha). Compared to the seated asana, or sitting meditation posture, of Patanjali's Raja yoga, it marks the development of asanas (plural) into the full body 'postures' now in popular usage. Hatha Yoga in its many modern variations is the style that many people associate with the word "Yoga" today.
Goal of yoga
The goal of yoga may range from improving health to achieving Moksha.Within Jainism and the monist schools of Advaita Vedanta and Shaivism the goal of yoga takes the form of Moksha, which is liberation from all worldly suffering and the cycle of birth and death (Samsara), at which point there is a realisation of identity with the Supreme Brahman. In the Mahabharata, the goal of yoga is variously described as entering the world of Brahma, as Brahman, or as perceiving the Brahman or Atman that pervades all things. For the bhakti schools of Vaishnavism, bhakti or service to Svayam bhagavan itself may be the ultimate goal of the yoga process, where the goal is to enjoy an eternal relationship with Vishnu.
