Just for the record Yogananda gave Hong Sau and the traditions say Ham Sa and some reverse and say So Ham or some So Hung. Is this just variations of regional language or eg does Ham sa actually pronounce like Hong Saw.
Just something that I wondered about for many years and there seem to be a few mantra exponents here Thankyou
I had been doing this method for a few years till I started AYP. Now I dont do it often. What I do is repeat SO on inbreath and HAM on out breath then HAM on inbreath and SA on out breath. This is dont repeatedly depending on the flow of breath. I have found this to be very relaxing.
I puzzled over this for awhile some years ago because it felt abstract, but it is really not. the Saa song is not from the tongue as it is spoken but more the sound of the in breath vibrating the sinuses in the head as the breath is taken in and smelled and the prana is absorbed from the nasal cavities. The Haam sound is the exhaled breath vibrating the throat as the warm released breath leaves the body,so that by doing that mantra the harmony of breath comes. Doing the opposite doesn't feel as harmonious to me but maybe it is an energetic reversal of some sort.
