Soft Focus - Open Focus

I've been fooling around with this simple exercise:

Open eyes wide in amazement - you naturally smile when you do this.
Keep blinking naturally, but 'soften the focus' and especially relax all
the muscles around - and BEHIND - the eyes.

The minute I do this, a kind of vibration begins - I estimate it's vibrating at about 10 cycles per second - and a flow of energy begins in the solar plexus, arms, hands, etc. I can hold it for about a minute or so, and then seem to 'plateau' out on it - this always has been my problem -- bumping up against my bliss tolerance, so I have to consciously relax more. But I'm really EXCITED about what an easy gateway this is to what writer Mihaly Csikszentmihalyi defined as 'Flow' in his book "Flow: The Psychology of Optimal Experience."

Serendipitously, while cleaning up my desktop on the 'puter, I ran into a .pdf I must have downloaded at some point on an 'Open Focus' essay and exercise that seems to be on this same wavelength. It's a little more involved than mine, but looks very good!
I think I may record it and then just listen to it. Here's the basic exercise they include. It's a little more detailed than mine, so why not try mine first (smile):

* The reader may wish to participate experientially
in the exercise. If so, in order to experience
beneficial effects, it is important to
allow at least fifteen seconds for each image.
For instance, can you imagine the space between
your eyes . . . (15 seconds). . . ears . . .
(15 seconds) . . . throat . . . (15 seconds) .
the space inside your throat... your nose as
you inhale and exhale . . .
the space between the tip of your chin and
the inside of your throat. . . between the
space inside your throat and the space inside
your ears... between the space inside
your throat and to the top of your head...
between the space inside your throat and
the space behind your eyes . . .
that your jaw . . . cheeks and mouth . . .
tongue... teeth and gums... lips are filled
with space .. .
the space between your upper lip and the
base of your nose . ..
that the region around your eyes and
behind your eyes is filled with space ...
that your eyes . . . eyelids . . . nose and
sinuses ... the bridge of your nose is filled
with space . . .
that the region between your eyes and the
back of your neck... between the bridge of
your nose and back of your head . . . between
your temples is filled with space ...
that your forehead . . . brain . . . spine is
filled with space . . .
that your whole head is simultaneously
filled with space. . .
that your whole head and your face are
simultaneously filled with space . . .
that your whole head, face, neck and your
whole body, includingyour hands, genitals
and feet are simultaneously filled with
space . . .
that your whole being fills with air when
you inhale and your whole being is left
filled with space when you exhale . ..
at the same time that you are imagining the
space inside your whole body, is it possible
for you to imagine the space around your
body, the space between your fingers and
toes, behind your neck and back, the space
above your head and beneath your chair,
and the space in front of you and to your
sides. . .
that the boundaries between the space inside
and the space outside are dissolving
and that the space inside and the space outside
become one continuous and unified
space.. .
that this unified space, which is coextensive
inside and outside, proceeds in three
dimensions, front to back, right to left, and
up and down ...
that, at the same time you imagine this
unified space, you can simultaneously let
yourself attend equally to all the sounds
that are available to you, the sound of my
voice, the sounds issuing from you (and
other members of the audience), and any
other sounds thatyoumay beable to hear...
that these sounds are issuing from and pervaded
by unified space . . .
that at the same time you are attending to
the space and the sounds you can also attend
simultaneously to any emotions, tensions,
feelings or pains that might also be
present. . .
that these sensations and perceptions are
permeated by space. . .
that at the same time you are aware of the
space, the sounds, emotions and other body
feelings, you can also be simultaneously
aware of any taste, smells, thoughts and
imagery that might be present. . .
that you can now admit also to awareness
any sensation or experience which may
have been inadvertently omitted thus far,
so that you are now simultaneously aware
of your entire being, of all that is you . . .
that all your experience is permeated and
pervaded by space...
that, as you continue to practice this Open
Focus exercise, you will increase your ability
to enter into Open Focus more quickly and
more completely and more effortlessly . . .
that, as you continue to practice this Open
Focus exercise, your imagery of space will
become more vivid and more pervasive...
that, as you continue to apractice this Open
Focus exercise, your ability to imagine
space permeating all of your experience
will continue to become more vivid and
ever-present.. .
