Another articulation of what Tolle says that is straight from the eastern source is in the Upanishads. It is an allegory that goes something like this:
There is a tree. In this tree perch two birds. One bird eats of the berries. The other bird perches silently and watches.
In Heideggerian terms I would say that the “room within which the furniture is” is what Heidegger is disclosing in his discourse on Dasein as Being-The-There.
The bird that “perches silently and watches” is what Heidegger is disclosing in his discourse on Dasein as Being-In-The-World.
The bird that eats of the berries of the tree is what Heidegger would call the “I” or the “Here”; the berries would of course be what Heidegger calls the “Over-There” where Handy things and other Daseins dwell.
Heidegger came to this realization via a logical deconstruction of the western philosophical tradition.
The eastern mystic came to the same realization via a method of silent contemplation of phenomena. By just listening to their experience; both inner and outer (which I believe to be another construction of the internal dialogue); I mean listening in the sense Heidegger uses the term: that is heedful listening, the east realized Being-The-There 1000s of years before the western philosophical tradition did.
