One of Yoga’s most subtle and yet deeply powerful tools is Prāṇāyāma. In fact, Sri T Krishnamacharya highlights the practice of Prāṇāyāma as one of the highest forms of Tapas, or discipline done to eliminate impurities from all dimensions of the body. According to the Hathayoga-pradipika, the improper practice of Prāṇāyāma may lead to different illnesses; however, when properly and systematically practiced, under the guidance on an experienced teacher, Prāṇāyāma can offer diverse physical and mental health benefits. These master classes comprise a brief theoretical introduction to the concept of Prāṇa, its connection to breath and mind and its usage in various techniques of Prāṇāyāma. Participants will be gradually led through progressively intensifying practices involving the use of breathing ratios and the incorporation of Bandha-s and Mudra-s in Prāṇāyāma.
