A shifting refuge….
First, we take ourselves to be a me. This human self and its body, identities and roles in the world. There is an inside and outside, and it all seems real and substantial.
Then, we may notice that the me is content of experience, it comes and goes as any other content of experience, and it is not what I am. There is a softening or release of identification with the me. This process can appear as a dark night of the senses, called so since there is a release of identification with the senses. The temporary outcome is an absence of a sense of inside and outside, a recognition of all as awakeness itself or God, and possibly insights, clarity, bliss, a clear inner direction and so on.
The remaining refuge here is the separate I and the spiritual joys mentioned above.
Finally, we may notice that the separate I is content of experience as well. The doer, thinker, chooser, owner, observer – all of those – are content of experience just as anything else. That too comes and goes. That too is not what I really am. As I keep noticing this, maybe first in formal practice and then in daily life, there is the possibility of a softening and release of identification out of these. This process is called the dark night of the soul, experienced as a death of the core of what we take ourselves to be.
When identification is released out of the separate I, what is left is doing without doer, thinking without thinker, observing without observer and so on. Everything is as before, although now all content of experience – including the doer and observer – is recognized as living its own life. The center falls out, and the bottom or ground falls out.
