If I consider the dark night that comes before this stage of union as a time of germination, then perhaps this stage is one of re-birth into a new reality.
To try and understand this more fully I once again looked to the mystical poets and Hafiz (as translated by Daniel Ladinsky) once again gave guidance:
The Seed Cracked Open
It used to be
That when I would wake in the morning
I could with confidence say,
"What am 'I' going to
that was before the seed
Now Hafiz is certain:
There are two of us housed
In this body,
Doing the shopping together in the market and
Tickling each other
While fixing the evening's food.
Now when I awake
All the internal instruments play the same music:
"God, what love-mischief can 'We' do
For the world
Does my SoulCollage® card have any wisdom for me?
Take it one step at a time.
The way is always clear.
Let light guide your path towards the Light.
