Just a quick note on my experience with mulabhanda so far. I just started to practice it about a week ago. It was very "clunky" at first, it took about 3 days before it became comfortable.
Its amazing what a huge boost it gives to those blissful feelings arising during pranayama. I've been doing spinal breathing for a while and just the addition of this simple bandha has had a tremendous effect on my practice.
The integration of the best yoga practices out there (thank you Yogani
) really does make a difference.
