Everything in this book belongs to the beginning of the path. The books describe what lies far beyond it. It is worth knowing in outline, if only so that the beginning is not mistaken for the end.
They describe three mountains. The first is Initiation: the long work of building the inner bodies with the kept energy, until a person is born again in spirit. The second is Resurrection: the death of the selves, all the way down, until nothing false remains. The third is Ascension: a return to the Being, whole.
Each mountain takes years, often lifetimes. The books are frank that few climb all three. They are also clear that everyone who sincerely walks the beginning is already on the road. Death, birth and sacrifice, done today, are the first steps of all three.
So there is nothing here to practice yet, except the beginning. Keep the three factors. Keep the night. Keep the Being in view.
The summit is not your concern today. The next step is.
