Science of Yoga is as ancient as our universe, indeed it is coterminous with its creation. Krishna in chapter four of the Bhagwadgita tells Arjuna that "He had explained the immortal science of Yoga to Sun who passed it on to his successor" He further stated that over a period of time Yoga nearly vanished from earth. Krishna through his discourse to Arjuna, sought to revive this most ancient and most profound practice. The current followers and practitioners of Yoga have somehow limited this great science to asanas, physical postures and have completely missed its spiritual and deep metaphysical power and potential. Based on extensive research on Bhagwadgita, Upanishads, Yogasutras, and Ashtavakra's Gita, this book seeks to present India's most powerful gift to mankind by presenting The art and science of Yoga with four distinct paradigms, comprehensively covering all elements of Yoga. Bhakti Yoga - Foundational Yoga with faith and devotion as the main instruments. Karam Yoga - Detachment and selflessness leading to excellence and purity of mind. Raja Yoga -Meditation in achieving stillness of mind and deep concentration. Gyan Yoga - Realisation of truth and ultimate reality. Removal of ignorance and delusion. Read less
