Stand straight with feet apart, about shoulders' width. Find a perfectly balanced posture. Breathe in slowly, gathering the qi in the general Dan Tian, an area three inches below the navel.  On the exhale, send the qi to the Gate of Life, which is a point on the spine across from the navel, and from there out to the arms, hands, legs and feet. 

Practise for about thirty six breath at about six breaths per minute.

You can also do this qigong while lying down and facing up.

This exercise can be used for calming down.
