There is a version that the origins of yoga traditions are in Egypt. And they got there, most likely, from Atlantis. According to archaeologists, yoga traditions existed 2500 years ago, while oral legends and traditions of yogis are much older.
Yoga is considered a traditional exercise system closely related to Buddhist religious philosophy. Yoga exercises are recognized as the best method of knowing the world around you and your own capabilities.
Yoga traditions are described in the work of the Hindu Patanjali "Yoga - Sutra", created in the first century AD.
This work defines all the basic concepts and methods of yoga exercises.
The goal of yoga classes is to educate a person morally, spiritually and physically. This is a whole complex system, universal in many respects. The ultimate goal for a follower of yoga teachings is the achievement of Samadhi - unity with the whole world and humanity.
In our time, the concept of "yoga" means most often hatha yoga, ie. body exercises. Hatha yoga is aimed at harmonizing energy flows in our body.
Such classes are nowadays available to the overwhelming majority, they are carried out in almost all fitness centers.
