I have been thinking about the "double realm" since I heard Tami Simon (Sounds True) interview Brother David Steindl-Rast a few weeks ago on this topic. Brother David is founder of the Gratefulness.org website and just had his 90th birthday.
He thanks
Echart Tolle for this phrase "the double realm" in the sense that it was the latter's teaching on "the Power of Now" that introduced Brother David to the possibility of experiencing the double realm: i.e., when we practice being in the power of
"now" it removes us for those few seconds or that time from the daily time-bound and focused pre-occupation and opens within us a sense of the eternal. At moments, we are aware of both at once, and this is "living in the double realm."
I know this place. I experience it frequently, the moreso as I advance in age, and sometimes unexpectedly. It is spacious and expanding, and relieves immediate concerns.
I recommend it as a healing and grounding practice for our pressured and crowded
days. For the interview itself, search for "Tami Simon's interview of Brother David Steindl Rast on his 90th birthday."
