This FBA Dharmabyte, 'Whole Body Breathing', is an excerpt from the talk Anatomy of the Breath by Padmadarshini.
This talk provides a really good working context to help your meditation practice. Best to lie down comfortably as you listen to Padmadarshini's description of the anatomical and physiological processes involved in breathing. She's a yoga teacher as well as a meditation teacher and she draws on both those sets of skills to give this talk. And as you lie there, she'll help you tune into your own own body with some very simple exercises and suggestions.
Expect to come away with some very practical tips on how to become more aware of your breathing body.
The talk was given on "One Moment at a Time" retreat at Taraloka and is a companion talk to the body scan meditation led by Vidyamala. (The sound quality is a little bit 'fuzzy' in parts but the content more than makes up for that.)
