I haven't tried it rigorously or by its name in the sense that I
understand it could be practised.
However, part of my own personal spiritual practice/consciousness has
been derived from the sense of the Russian Pilgrim, the practice of
the presence of God, perpetually.
That for me has meant, to seek to be open, embrace reality, and accept
my/our responsibility for all things. When I open my mind to that
vibrational dimension, I do notice that things happen magically (eg,
my earlier posts about Heaven on the Underground and the other one
about being missed by a roof tile).
Everything is connected, and everything is one. Even so, separating
off a different or special time for meditation or prayer can create a
separateness; so my feeling is that the prayer of the Heart is best
when it is perpetual, no separation from the everyday, which then
evokes and pushes us into that dimension of univeral healing.
I could be wrong, but I think the many paths of divinity converge,
cross over in an permeable web/seam. Such that different names of
different practices are simply different terms for a common unity.
I feel that this is what the Angels wish for us, and encourage in us;
that too is being a little like them, in their constant, inseparable
unity with, and service of, the Divine.
Namaste
Paul
