I thought the point to take away, is that mind is not separate from environment. And futher questioning the inner / outer distinction which causes a sense of separation and disconnectedness.
edit: for me it echoes a recent post from Riccardo Manzotti's "spread mind" theory:
"Are subjective qualities really more private than objective properties? Or are they the conceptual byproduct of two different ways to address the same stuff?"

As Alan Watts beautifully put it:
"Every way in which you define your self, can be described in terms of other"
ie. just find a single part of "personal" experience that can not be defined as non-personal. arms, legs, face ? those are the body. memories / thoughts? Are obviously made of some kind of echo of sense experience. Content of recent thougghts? Obviously in response to recent experiences or concerns, which themselves again are not self, and never originated as "self".
