It releases the energies that involve, cling, wrap, smother or blind. It's simple almost magical and can be practiced in a fraction of a second. This was a gift to me from my sister. Most know it already (I'm a late bloomer).
It is a conscious effort to rest from the gut. Only takes a second. It helps me see clearly, love directly and be fully. I practiced it every day at the wooden gate leading to my sister's house when she was was dying from cancer. It clears everything and lets the happy in.
