Group activities are often begun with a quiet, lead meditation that in the Gurdjieff tradition is called a sitting. In addition to group sittings, group members are encouraged to make a personal sitting a part of their daily practice.
"A true sitting, in my estimation, would be a choiceless seeing of what is taking place as moment by moment passes.  A true sitting means an unflagging attention coming from a still place in oneself. There's no judgement, no grasping. There's no wishing even, just sitting."
- William Segal in A Voice at the Border of Silence
