Martin,
I think it's because it's at the soul level.
Our identity is stripped here and we are all searching for the truth.
One tribe on a quest and a goal.
There is unity here and it's not bogged down with other stressors that are in the daily life.
The only interaction is thought.
Most of it positive or revealing.
AU is a special place
and we are family
but at the end of the day you can't touch or hold like your wife or children.
That, in itself, the lonely anon would trade you for in a heartbeat.
Each day here we are blessed with knowledge and discernment.
Each day in our family lives we have a chance to take what we've learned here and put it into physical action.
Teach them.
I know you can.
