I know I did, for a long time - but they're an important part of helping to differentiate the types. I feel that a lot of people, when trying to identify their type, seem to be debating very inconsequential details, when the biggest differences aren't being discussed at all - and often stare them in the face.
- There's a reason 5s, 6s and 7s are in the head triad - these people identify with their minds, in ways they may not be fully aware of. They "think" more than others, but it's done compulsively - they interact with the worlds from their minds. Their thoughts create so many possibilities that they may become overwhelmed with fear at times, unable to make confident decisions. They must learn, time and time again, how to take decisive action comfortably when overwhelmed with fear.
- There's a reason that 2s, 3s and 4s are in the heart triad - these people identify with their hearts, much the same way that the previous types identify with their minds. This isn't just a figure of speech - their hearts are what guide them through life. They can become so reliant on emotional connection and the images they adopt that they can neglect everything else about life. They must learn to "take off" the mask when emotional distance is needed.
- There's a reason 8s, 9s and 1s are in the body triad - these people identify with their bodies, and live through life from the gut. They compulsively identify with the physical presence in the world. They can become so comfortable in their bodies that they become "too" autonomous - like rocks embedded in a riverbed. In their stances 8s become too unstoppable, 9s too laid-back, 1s too rigid.
I'd love to see more discussion in this regard - how the types reflect their triads.
