Yoga has been accepted as a way of life by so many people around the world irrespective of the religion and country. There is world wide promotion for Yoga and June 21 is going to be celebrate as International Yoga day.
As wikipedia says,
Yoga (/ˈjoʊɡə/; Sanskrit: योग, Listen) is an Indian physical, mental, and spiritual practice or discipline.The word Yoga comes from the Sanskrit root “Yuj” which means “to join.”Yoga is Chitta-vritti-nirodhah, restraint of the mind-stuff or the psychological apparatus inside, generally known as the mind. The different ways of controlling the mind or restraining the Chitta constitute the whole procedure of Yoga.
There are many religious aspects and sects in yoga but the the famous one Ashtanga Yoga was introduced by Yogacharya (teacher) Patañjali in India.
The yogis in India has been following the practice thousands of years ago as a part of their spiritual tradition. As a part of their religion both buddhist and Jains was also familiar with their style of meditation and yoga. When comparing the practice of Yoga with eastern countries, the west just started the practice (as a widely accepted exercise or as a spiritual practice)recently.
So my question is, who carried the major role in introducing the Yoga to the west? When did people in these countries started to follow Yoga as a major practice in their daily life? Is there any references for the same in past 100 or 200 years?
