I'm starting this thread to hold resources about Open centers.
Having 2 open centers myself (head and G/self centers), this was an important piece of my own puzzle.
And I think it's what lead me straight down the seeing Notself themes in the lives of everyone around me and ultimately it surfaced, as you maybe already know, as a theme for my primary guidance.
For clarity in this context-
Open = no gates activated on a white center
Undefined = one or more gated activated (but dormant) on a white center
The key difference in the two is in Amplification potential - they're both still prime real estate for our Mind to use for sidestepping our Inner Authority to make decisions.
This is a Ra passage that expands on that part:

Can drop further resources into comments :)
