"The easy confidence with which I know another man's religion is folly teaches me to suspect that my own is also." - Mark Twain
You might call personality the most core religion. The sum of what a person believes is presently true. The ease at which I can see un-reality or un-presence in the beliefs of others leads me to suspect my own. This is the universal mirror.
Knowing that my own view of the world is suspect allows me to question it, no matter how "solid" it seems. But like shaving without a mirror, though possible and at times necessary, it's simply inefficient. From the inside it's far more complicated to see the difference between my memories and my present because, from the inside, I experience it all as "now". To a conscious observer only my present is happening now because they don't share my memories.
A circle of knowing is a group that chooses to use each members vision in order to burn all beliefs, and see together, creating a higher order being. It's not people who agree on anything. It makes no difference what each individual believes. What matters is that each member brings their solid independent energetic vision to the group, and can listen and use the vision of others.
In the unconscious journey, feedback often means to judge what I see in others and avoid seeing it in my self. It means to fight against any unflattering image, making the mirror the enemy, or to shut up for fear of becoming the messenger of "bad news". This makes the concept of living with feedback rightfully unappealing. The conscious journey, however, honors and uses the mirror, even if painful, as a tool for self awareness.
Giving awake feedback happens when you no longer seek to judge, which is living awake.
As an individual, even awake, such feedback is often prone to misuse and often links the one offering feedback with the source of pain. Any individual practicing this must tackle people directly and personally. An awake group practicing feedback is no longer personal and therefore less fragile and less suspect. Each person seeing with their own unique energetic eyes greatly increases the accuracy of the combined energetic vision and greatly reduces the interference of each individual's beliefs.
To play in such a group, like relating awake, requires the unbending intent to live awake. It's not a verbal statement, but an energetic one, regardless of what you would like to believe about your self. A group must be picky only in this aspect. It's not only for the benefit of the group, but also to protect those who would rather keep their beliefs, from harm.
The intent of such a group of knowing is to play in the "field beyond ideas of right and wrong" - Rumi. The play is not limited to "spiritual" or "special" things, nor to a special time and place. It's simply a "language", a paradigm of awake group interactions.
"It is possible that the next Buddha will not take the form of an individual. The next Buddha may take the form of a community, a community practicing understanding and loving kindness, a community practicing mindful living. This may be the most important thing we can do for the survival of the earth." Thich Nhat Hanh
