Yogamaharishi Dr. Swami Gitananda Giri was a medical doctor. He combined his scientific background with the ancient techniques of classical Yoga that he studied in his youth with his Master, the Bengali saint Sri Swami Kanakananda. The result is what Swami Gitananda called "Rishi Culture Ashtanga Yoga" and is now known as "Gitananda Yoga". The beauty of Gitananda Yoga lies in its step-by-step approach towards Yoga that is also beautifully outlined in the correspondence course "Yoga: Step-by-Step". Based on moral and ethical values (Yama and Niyama) Swami Gitananda taught: Asanas (Body postures) Pranayamas (Breath-energy controls) Kriyas (Systematic movements) Mudras (Gestures of energy) Taken to their full potential the values and techniques Swami Gitananda taught can lead the student to the experience of Yoga (unity).
