Acharya Prashant clarifies that the popular perception of Yoga as a series of physical postures and exercises is a distortion of its true meaning. He explains that while physical activities like Hatha Yoga have health benefits, they do not constitute the essence of Yoga. True Yoga, as defined in the light of Vedanta and the Bhagavad Gita, is the union of the mind with the Atman (the Self). He emphasizes that the Atman represents the purest and highest state of the mind, and India's greatest contribution to the world is this concept of the Atman, which suggests that the ultimate truth and power reside within one's own consciousness rather than in external deities or physical forms.
