Law of Three, an introduction
Threefoldness is at work in every event. In fact every event is defined by the three forces at work. A way of speaking about sleep is not only that we are third force blind, but we are also second force blind. Identification is attachment to the affirming or denying, pushing or resisting, to the exclusion of the opposing force. The portal to contact with the third or reconciling force is to allow the affirming and denying to meet in ourselves.
Gurdjieff said "like what it doesn't like". This means choosing to enter into the unpleasant, not to overcome it, but allow the opposing impulses in myself to come in contact, engage, and give rise to the subtle.
Also-- "Bear the manifestations of others. This is the last thing for a [hu]man." To be able to bear others is opening to actually entering into the experience of others, to have Compassion in the true sense.
To be able to hold the yes and the no, and invoke the reconciling and harmonizing is to bring harmony. "Blessed are the Peacemakers, for they shall be called the daughters and sons of God."
For now try to observe the three forces at work -- they are there in every interaction, every activity, every event.
Specifically (and I didn't think of this until after the meeting), sense the weight of things. We are constantly carrying objects around (including our bodies). Try to be aware of the weight of everything you come in contact with, doors, glasses, bags, your body. This is the denying force in the physical sense -- be aware of it, feel the weight of things.
