I will be leading an online retreat from the 15th to 17th January 2021 using Zoom. The topic will be "Spinal Breathing Pranayama and the purification of the subtle nervous system". We will be looking at the fundamentals of the practice of spinal breathing and also at more advanced aspects, such as automatic breath suspension and the ways in which the flows of prana in the body change, leading to increased purification. We will also look at the ways in which pranayama leads to the purification and activation of the chakras.
