Is yoga the same thing as sophrology?

Caycedo, the founder of sophrology, influenced by his French wife who was passionate about yoga, spent several years in India. There, he met great yogis who introduced him to breathing and meditation techniques, which had a profound influence on the discipline he founded a few years later, in the 1960s. Like yoga, sophrology bases its practice on the importance of breathing and visualization, thereby helping to combat stress and anxiety. But unlike yoga, sophrology involves very few physical movements and does not claim to have a profound effect on the body, its health, or its posture.
