In Leslie Kaminoff’s Yoga Anatomy, he addresses the Bandhas in the introductory remarks about breathing.
“Along with the rispiratory diaphragm, breathing involves the coordinated action of the pelvic and vocal diaphragms.” p.13
Three diaphragms! Even in cadaver lab this was never apparent to me, but once spotlighted the simplicity is inescapable! To make it even better – more elegant, explanatory, integrated & just plain cool! – the central tendon of the respiratory diaphragm is part of the pelvic floor. Thus the connection between mulabandha, or pelvic floor toning, and breathing, as well as stabilization of the spine and torso.
I’m polishing up the handouts for my Heart Opening Workshop tomorrow, one in which we begin with the premise that all the many levels on which people seek heart opening begin with deep anatomy of the neck, shoulders and core. To be clear, I include in “core” all muscles and connective tissue in a diamond shaped area from the inner knee, out to the pelvic edges, up to the shoulders with the top at the hyoid bone.
One of the introductory exercises we’ll engage is Simhasana, or Lion’s breath and I was intrigued to find in Light on Yoga that Iyengar mentions the tonifying action on all three bandhas. This makes sense now that I more fully understand the connection between the diaphragm & pelvic floor. Furthermore, Kaminoff observes of malasana that pressing the outside of the elbows into the inside of the knees aids the action of drawing the rectus abdominus back & up, thus the diaphragm and that all of the bandhas are highlighted this way.
What poses have been the most enlightening of your bandhas?
