The 3 Subtypes
The Subtypes are three operational modes of each Type, which means that there are in fact 3 x 9 = 27 personality types in the Enneagram model.
The Subtypes represent three ways of experiencing our instinctual centre, whatever our initial Type: survival, one-to-one or social.
The Subtypes do more than provide nuances to the 9 Types: they underpin them, mark them profoundly. We cannot know ourselves well and work with the Enneagram without an in-depth knowledge of the Subtypes.
As they are instinctual, they are even more unconscious than the Type and need to be the subject of unrelenting self-observation in our day to day lives.
