5. So should one have no thoughts? It is impossible to have no thoughts.
Should one not breathe? It is impossible not to breathe. Nothing compares
to making the affliction itself into medicine, which means to have mind and
breath rest on each other. Therefore tuning the breath should be included in
turning the light around.
6. This method makes use of two lights. One is the light of the ears, one is
the light of the eyes. The light of the eyes means the external sun and moon,
combining their lights; the light of the ears means the internal sun and
moon, combining their vitalities. However, vitality is congealed and
stabilized light; "they have the same source but different names." Therefore
clarity of hearing and seeing are both one and the same spiritual light.
7. When you sit, lower your eyelids and then establish a point of reference.
Now let go. But if you let go absolutely, you may not be able to
simultaneously keep your mind on listening to your breathing.
8. You should not allow your breathing to actually be audible; just listen to
its soundlessness. Once there is sound, you are buoyed by the coarse and do
not enter the fine. Then be patient and lighten up a little. The more you let
go, the greater the subtlety; and the greater the subtlety, the deeper the
quietude.
9. Eventually, after a long time, all of a sudden even the subtle will be
interrupted and the true breathing will appear, whereupon the substance of
mind will become perceptible.
