1. History of Yoga
Yoga is a physical,Mental, and spiritual practice or discipline
that express a variety of practices and goals. Yoga is a
technique to control the body, weight loss , boost the mind
as well.

2. Origin of yoga is already the part of debate. Yoga may have pre-Vedic elements.
There is no adaptation on its chronology or specific origin other than that yoga
developed in ancient India. There is no any specific date mentioned the origin of
yoga. Our best evidence to date suggests that practices developed in the same
ascetic circles as the early sramana movements (Buddhists, Jainas and Ajivikas),
probably in around the sixth and fifth centuries BCE.
According to the Rig-Veda the first use of the root of word “yoga” is in
hymn 5.81.1. A dedication to rising Sun-god in the morning, where it
has been interpreted as “yoke” or “yogically control.
To understand the origin of yoga we have divided into four periods:
The Vedic period, Pre-Classical Period, Classical Period, and post classic
period.

3. Vedic Period
During this time, the Vedic people relied on saints or dedicated Vedic Yogis to teach
them how to live in divine harmony. Saints were also gifted with the ability to see the
ultimate reality through their intensive spiritual practice. It was also during this time
that Yogis living in seclusion (in forests) were recorded.

4. Pre-Classical Yoga
The formation of the Upanishads point the Pre-Classical Yoga. The 200+
scriptures of the Upanishads describe the inner vision of reality resulting
from faithfulness to Brahman. These explain three subjects: the
ultimate reality (Brahman), the transcendental self (atman), and the
relationship between the two. The Upanishads further explain the
teachings of the Vedas.

5. Right now Yogis attempted to use Yoga techniques to change the body
and make it immortal.
Classical Period
The Classical Period yoga is pointed by
another formation – the Yoga Sutra.
Written by Patanjali around the second
century. It is composed of 195
aphorisms or sutras (taken from
the Sanskrit word which means thread)
that expound upon the Raja Yoga and
its their underlying principle, Patanjali’s
Eightfold path of Yoga (also called Eight
Limbs of Classical Yoga).

6. Post-Classical Yoga
At this point, we see a generation of biography as well as the practice of
Yoga. Post-classical Yoga differs from the first three since its focus is
more on the present.
It no longer strives to liberate a
person from reality but rather
teaches one to accept it and live at
the moment

7. The most prominent of his works is his modified Five Principles of Yoga which are:
And the Yoga continues with the generation and increases its teachings,
crossing the boundaries of culture and language for fight with the
different types of disease.
