Orbit Acupressure
Given that "opening the orbit" is - in the HT system - the prerequisite for all of the Taoist work, it's surprising that, in a Taoist discussion site poll, only one person in eight had practiced orbit acupressure. Its one of those approaches that is so obvious that no one thinks of nor tries it, yet it's one of the most effective - both for initial opening of the orbit and for maintenance.
Much of orbit acupressure can be done by hand, with no special knowledge; all that's needed is a sense of curiosity, of exploration. Its not necessary to know the formal names, locations, functions of the acupoints. Simply massage the places that you can reach, all along your center line, and feel for places that are a little tender or sore, or that you are curious about. You want to create a flow through the orbit, so massage several areas, not just one.
Several massage tools are helpful (pictured below) for massaging the back, front, and for massaging more deeply than is easily done with the fingers.
It's that simple. :)
Old tennis balls in a sock as back roller.
"Front rollers". Another must-have.
For some points on the abdomen that might need more pressure.
