The principles laid out in Patanjali’s yoga sutras dating back to 500 B.C. are still very relevant today, even in our modern information world. Yoga has evolved a lot from the days of Patanjali; it has taken different forms to meet the varying needs of practitioners all along its journey. Yoga continues to accept all changes, like the ocean accepts the river, absorbs, assimilates and grows. (A distinctive feature of sanaatan dharma of India)
