Yesterday's answer, today's query

ANSWER: Oh, wow,so many answers:) And Thin Air, was that an answer or a rhetorical question?
But, yes, all you smart people, the answer is the  mmmmm sound... U will find that u can start off strongly with the Ah, but taper off without strength in the Mmmmm.. and so, it is a good sound to invest in, if u want to make your lungs strong.
Somewhat related to this subject, is the following query...

QUERY:  In Bhramari pranayama -- the mmm, or humming bee pranayama -- the sound u make, mmmmmm  - is that an  exhalation or an inhalation? Think about it, the sequence of instructions will give u a good clue:)

Yes, Watsons, I await!
