This is the third practice of this part. It comes from an old teaching on the runes, the signs of the ancient North. In the tradition each rune is a posture of the body, joined to a prayer and a sound.
Fa is the first. It turns the first minutes of the day into something awake: body, breath, prayer and attention, all at once.
The sun gives life to everything on earth. In the tradition it is also a symbol of the Christ of page 67: the divine light that can be born in anyone. Standing before it with open hands, you ask for strength and for your consciousness to wake.
It is also a breathing practice, and a way to turn the creative energy of Part III into wakefulness instead of spending it.
Do it outside if you can, facing the sun. If the morning is cloudy, face where the sun is. If your arms tire, lower them between rounds. That is part of the practice.
The free course Runology, in My Courses, teaches all fifteen runes in the same plain way, one page each.
