In mantra or Akshar Yoga there is a special mention of sibilants of the HS sounds.
In the first week of May, I was in Antigua for the GAPIO meeting and found that the GAPIO meet was full of energy. The people in the meet had some S/h or H in their names. To name a few they were Dr Sanku, Dr Sibal, Dr Sudhir, Dr Krishan, Dr Ramesh, Dr Shankar, Dr Sharma, Dr Singhal, Dr Sheth and Dr Hemadhri.
This was a coincidence, but it reminded of a Vedic saying that it’s the people who make any organization vibrant.
S and H sounds in our life energize our body like in Om Shanti Shanti Shanti. Keep watching and you will find there is a little bit of H or S in everyones life.
About S and H Sibilant (ushma the energy sounds) sounds श् ष् स् ह्
Sa and Ha sounds govern the breath. Our breath has a natural hissing type sound and is released with a Ha-sound.
The root Sa means to take in, to inhale, to energize, to hold, to take power, to sit, to rule, to endure, and to set in motion. The sound-Sa, therefore, is the natural sound of inhalation.
Ha as a root means to give out, to exhale, to leave, to abandon, to negate, to ridicule, to cast out, to throw, and to ward off. The sound Ha, conversely, is the natural sound of exhalation.
श् is the more important of the two. It is the seed bija sound of peace, which is Shanti. It relates to Shankara. It is calming, harmonizing and balancing. It is cooling. It means to quiet, stop, or dissolve, and also to beautify, shine, or diffuse.
These sibilants energize our prana, directing the force of Shakti through the nervous system and the spine. Many Shakti mantras arise from Ha and Sa. These sounds create heat and electrical energy, stimulating not only the breath but also the Kundalini Shakti.
ह् and स् together as in Hsauh create a powerful sound for energizing the serpent power. The Sa-sound has a special combination with the त् थ् consonants, particularly in the root Stha meaning to stand’.
