Breath, this is one of the primary element used for a Qi Gong 18 Style Ritual Practice. How we breath, the way we breath, where we focus the breath is extremely important.
The proper way to breathe while performing your Ritual is:
Place the tip of the tongue on the roof of the mouth.
Inhale and Exhale through the Nostrils. Not the mouth.
Inhale from the Perineum (mid-way between the anus and the genitals) drawing the breath up the spine, over the top of the head and into the nostrils. Exhale through the nostrils down the mid-line of the body to the Dan Tien (four fingers below the navel) then internally back to the Perineum. Imagine the breath moving just outside of your body as if in a channel or tube. It is actually. This is the Micro Cosmic Orbit.
With the Inhale the Dan Tien should be expanding. When you Exhale the Dan Tien should contract.
The length of the breath should equal the movement eg, inhale as the arms raise, exhale as they lower etc.
The breath should be smooth, easy and silent.
It is that simple. Yet it is also very powerful.
