A Review on Yoga Therapy
The Sanskrit word “yoga” comes from root yug (to join), or yoke (to bind together). The word “yoga” has come to describe a method of discipline: to join the body to the mind and together join to the self or to union between the individual self and the spiritual self. Yoga is considered as an acceptable method for improving and maintaining physical and mental health. A growing body of evidence supports the belief that yoga benefits physical, mental and emotional health. Over the last 10 years, a growing number of research studies shows that the practice of yoga can improve strength and flexibility and cures various types of diseases like hypertension, diabetes mellitus, depression, etc. Yoga is a comprehensive system that uses physical postures (asanas), breathing exercises (pranayama), meditation (dhyana), concentration (dharana) and reflective practices.
Introduction
Yoga is a perfect practical system of self-culture. Yoga is an exact science. It aims at the harmonious development of the body, the mind and the soul. Yoga is the turning away of the senses from the objective universe and the concentration of the mind within. Yoga is eternal life in the soul or spirit. Yoga aims at controlling the mind and its modifications. The path of Yoga is an inner path whose gateway is your heart. The practice of Yoga plays a vital role in the rehabilitation of physically and mentally handicapped person as well as those who are socially disadvantageous [1].
Yoga is an ancient mind-body practice that originated in India and is becoming increasingly recognized and used in developed nations as a health practice for a variety of immunological, neuromuscular, psychological, and pain conditions [2].
The word yoga comes from the Sanskrit term “yug” and directly translates as “to unite”; more broadly, it means to work towards a unified experience of the self and improved health [3].
It was observed that practice of Yoga improved joint flexibility [4], respiratory endurance, and strengthening of muscles in young [5].
There are many traditional paths of yoga, including tantra, mantra, kundalini, bhakti, jnana, karma, raja yoga, and others, all of which have their own techniques to awaken these connections. According to the classic text of the Yoga Sutras of Patanjali, “yoga” is the complete “inhibition of the modifications of the mind” [6].
Yoga practices can increase multiple neurotransmitters and hormones such as GABA, serotonin, and dopamine—all natural anti-depressants. They have been shown to increase levels of melatonin, helping to initiate sleep, improving sleep quality and sleep regulation, as well as increasing levels of oxytocin, the “bonding hormone”, thus helping with feelings of connectedness and “being seen and heard” [7, 8]. Yoga is a form of mind-body fitness that involves a combination of muscular activity and an internally directed mindful focus on awareness of the self, the breath, and energy [9].
The eight limbs of yoga The Yoga Sutras, also known as The Eight Limbs (Ashtanga) of Raja. Yoga was the first fully developed and recorded system of yoga. Created by Patanjali around 400 BCE, this system influences much of the yoga that is practised today [10].

The different types of yoga that have developed in the history and the objectives and benefits of each type of Yoga. Schools of yoga or types of Yoga are set in terms of the objectives to be achieved and some general terms are: relaxation, breathing, yoga postures (asanas), concentration, inner detachment and devotion to God. Neither type of yoga is tied to a specific religion, so that both the believer and the atheist can practice his/her methods without principles imposed against their religious convictions.
