The actor one is

With the Fourth Way, as a way of development,
a student is given the opportunity to work on all
sides of himself. Emotionally, intellectually,
instinctively, and through movement. Although
it must be noted, that generally movement and
instinct are most often placed together. An example
of this might be the man who works on the physical
self. Walking, exercising, will over the body.
Intellectually, this is not so important in a sense.
There is a tendency to be weak in this area, but
as Mr. Gurdjieff said, "mind can be useful like policeman".
Our minds can remind us of a goal or aim, or to figure
out how to do something, arrange a train ticket for
example.Emotionally, the big work is the non-expression
of negative emotions, judgement, anger, rage, jealously.
This is the major part of the work. Observing the daily
actor one is performing.
