more awake and you can feel the life force flowing all over your
body.
Now to a certain extent, a similar movement takes place each time
you awaken a strong vibration in your eye, even if you do not rub
the hands: the astral is drawn into the etheric. Of course if the
purpose is to sleep, you want just the opposite! You want the astral
body to move away from the etheric and physical bodies. And you
want the etheric and physical bodies to become very quiet, not
vibrating all over. So quite logically, you should not try to
stimulate the vibration in the eye during night practice. If you
were to do so you might get agitated and find it difficult to fall
asleep.
This is a common reason why some people who follow a path of
meditation go through periods during which they can't fall asleep
at night. They may not realize it, but they unconsciously foster
the vibration in their third eye. It is like a clenching of the eye.
And, due to the above-mentioned mechanisms, they are kept
awake.
You can notably improve these people's sleep by helping them
become aware of what takes place, and getting them to release the
vibration in the eye. A good method is to focus on the heart. A
well known Sanskrit text, the Bṛhad-Āraṇyaka-Upaniṣad (2.1.17-18)
explains that to fall asleep there has to be a withdrawal of the
prāṇas (etheric energies) and the senses into the heart. A gentle
awareness (no concentration!) in the heart centre, behind the
middle of the chest, will favour the right gathering of the
energies, thereby inducing sleep.
13.7 Third eye flaring – a possible experience
If you follow a systematic training to build your subtle bodies, it
may happen that you go through a phase when a strong vibration
is automatically and permanently switched on in your third eye,
day and night. You are not even clenching unconsciously, it just
happens as a natural part of the process, and it often has to do
with the guides pouring energy into your structure. You feel your
eye quite intensely, there is a lot of vibration, and there can also
be a lot of light too. Sometimes there is so much inner light that
it feels like the middle of the day, even though you are lying
down in a dark room in the deepest part of the night. It may well
be that you can't fall asleep because the vibration in the eye is too
intense. Another common symptom is that you need to get up a
