I suspect inner integration is the key to tapping into all our power. The inner integration of shadow and light.
I’m hearing: it is the key to the kingdom. But that’s religion and religion is a mimic and it’s not the place of our true power.
You are It. Your inner integration of shadow- fear, guilt, self-loathing, doubt, etc- and light- joy, expansiveness, happiness, enthusiasm- is the key with which you unlock the deeper unlimited you.
You integrate by softening into. Not escaping through fantasy and ideology (as fun as that can be).
