This book is jointly authored by Yogachariya Jnandev Giri and Yogachariya Dr Ananada Balayogi Bhavanani. It will give the reader a deeper understanding of the Swaras, the breath cycles through the right and left nostrils and the interconnectedness and importance of having conscious awareness of these to live a yogic life. The Swara Yoga teachings come from "Shiva Swarodaya," an ancient Sanskrit Tantric text. This scripture or teachings are in the form of a dialogue between Lord Shiva and his wife Parvati. The text describes that Swara Yoga is useful for the transformation of our life and knowing how to perform various life activities based on breath, nostril and energy. Once we understand the connection of Swaras with Nadis, body parts, and Chakras, Swara Yoga can provide us many healing practices. In Swara Yoga it is described that the rst symptom of any physical and or mental problem can be seen is disturbance in biorhythmic change in nostrils. The modern equivalent of Swara is the nasal cycle which is an ultradian rhythm of nasal congestion and decongestion with a quasi-periodicity of 60 to 240 minutes. Though Keyser made the rst formal description and the use of the term nasal cycle in 1895, this concept and an understanding of its role in human life had existed for much longer in Indian thought. The Vedic science dealing with nasal cycle and its functions was known as Swarodaya Vigjnan (swara = sonorous sound produced by air ow through nostrils, udaya = functionality, and vigjnan = knowledge).
