We’re not in touch with an external shared reality, what each of us is in touch with is our private internal interpretations of reality, a reality for subjective impressions, subjective impressions that arise from the interaction of our innate temperament with a superficial experience.
The assertion that the self resides solely inside of us is a lie… the self is a flowing projection of state, of story, and a relationship between the inner and outer world. The self is an accumulation of impressions, it is not a steadfast object, unmoving and unyielding, instead, it is open to reinterpretation through reexamination.
