No One knows how old yoga is. It originated. It had been handed down and has gone evolution. The reference to Yoga was discovered when excavations were made from the Indus valley - an powerful and influential civilization from the antique period. This sophisticated civilization developed around the Indus river and the Sarasvati river in northern India and had sewage systems, baths as ancient BC.
 While religions continue To wish to create yoga their creation, it belongs to all people. It has several facets which can be seen in the Hindu and Buddhist faith, but the basic principals are universal and based on"the eight limbs of yoga", which can be found in all religions.
 The History of Yoga is described as four phases:
 Vedic Period, Pre-Classical Period, Classical Period, Post Classical Period and the Modern Period
 History of Yoga
 Yoga Is said to be as old as culture itself but the practice's oral transmission, has left openings in its history. Earliest archeological evidence relating to the existence of yoga is found excavated from the Indus valley, depicting a figure seated in a traditional yoga pose. The stone seals place Yoga's existence around 3000 B.C.
 The Vedic Period
 The next Reference to yoga is located in the Rig Veda, the earliest text on earth. The Vedas, dating back to 1500 and 1200 BC, are a group of brahmanical rituals and hymns, mantras which praised a being. Yoga is referred to in the book as subject or yoking with no mention of a clinic or a procedure to achieve this subject. The Atharva Veda too mentions yoga with a reference to controlling the breath.
 Pre-Classical Period
 The Introduction of the Upanishads, The term Upanishad intends to sit implies that the only way a student could learn the truths in the texts was sitting close to a guru.
 The Maitrayaniya Upanishad summarized a six-fold path to liberation. Patanjali's Yoga Sutra was to mirror these paths with a few additions and elucidation.
 Two yoga disciplines Gained prominence at this time: karma yoga (course of action or ritual) and jnana yoga (path of knowledge or study of the scriptures). Both paths resulted in liberation or enlightenment. The Bhagavad-Gita, composed around 500 BC later added the bhakti yoga (the path of devotion) for this route.
 It had been at the time of the Upanishads that the idea of Ritual sacrifice became the idea of sacrifice of the ego through action, self-knowledge and wisdom and was internalized. This remains an significant part the philosophy of yoga now. Much like the Vedas, the Upanishads comprised no matter what we would term as yoga asana practice now. The most important and first demonstration of yoga arrived in the next phase.
 Classical Period
 Written some Time in the second century, Patanjali's Yoga Sutras produced a milestone defining what is now called the first period. This set of 195 sutras (aphorisms) is considered to be the first systematic demonstration of yoga, also Patanjali is revered as the father of yoga.
 Patanjali described the route of yoga (ashtanga yoga), which explained a practical treatise on living and laid a path for attaining stability of the mind, soul and body. Strict adherence to which would lead one. Although yoga longer sees the need the sutras nevertheless serve as a principle for living in the world.
 Post-Classical Period
 It Was the belief of this human body as a temple had been revived and yogis designed a practice to rejuvenate the human body and also to prolong life. It was no longer required to escape reality; instead the focus was living in the moment and on the path. The quest of the spiritual and the halves and the necessity to harmonize the mind, body and soul led to the production of Tantra yoga, to Hatha yoga at the tenth or ninth century, and to cleanse the body and brain.
 Modern Period
 Yoga in its present avatar owes lots of To learned gurus who researched and generated schools of yoga, or traveled west to disperse the benefits of yoga. In 1893 Swami Vivekanada spoke about Raja yoga and addressed the Parliament of World Religions at Chicago. https://yoga-world.org introduced the five principles of yoga and wrote a few books. J.Krishnamurti, the prolific Indian philosopher, affected tens of thousands with his teachings and writings on Jnana yoga.
 The epicenter of modern day yogabegan in 1931 Mysore India, with Krishnamacharya.
 T Krishnamacharya started the Hatha yoga college . Three of Krishnamacharya's most famous pupils were-Pattabhi Jois, who developed the college of Ashtanga vinyasa yoga, Indra Devi who introduced yoga to Hollywood, and B.K.S. Iyengar, who generated Iyengar yoga known for its attention to body alignment and because of its use of props. 
 Since Then, many yoga gurus have become pioneers, finding new fashions in keeping with the times and popularizing yoga. 
 Yoga in America has been A yogi understands, although more concentrated on the practice's Asana side There is far more to the experience. I advise students Styles and you will find one which provides you the maximum enrichment.
