Draga is not Yoga, wich is deeply rooted in Hinduism, and is inherently tied to this religion. Many of the mantras and chants used in yoga, come from Hindu and Buddhist traditions, which can make it problematic for people who practice different religions, or have no religious affiliation at all.
It's important to note that while both draga and yoga involve physical movement, they have different origins, philosophies, and practices. Draga was developed in Scandinavia. It is not tied to a religion, it is simply a form of natural balance in movement techniques, that have a close connection to nature.
