This talk by Dr. Nalini is about prana. In living beings, the universal energy prana is considered responsible for all bodily functions through five types of prana, collectively known as the five vāyus. Tantra, ayurveda and Tibetan medicine all describe praṇā vāyu as the basic vāyu from which all the other vāyus arise. Dr. Nalini is giving lots of seminars in all yoga vidya ashrams every year. One of her seminars is also about prana healing and another one about pranic wellbeing. You can find them here.
