"Empty essence means very, very open
And very spacious, like a totally open sky.
Space has no center or edge.
Nothing is prevented, it is completely unimpeded.
Empty essence, like space, is not made out of anything whatsoever.
At the same time there is a sense of knowing,
An awake quality, a cognizant nature,
Not separate from the openness of this space.
Like the sun shining in daytime,
The daylight and space are not separate.
It’s all sunlit space.
Nothing is confined, nothing is blocked out.
All the doors and windows are wide open.
Like a total welcome – of all possibilities –
Which doesn’t get caught up in whatever happens.
It is wide open,
The unity of empty essence and cognizant nature.
This is the third quality, that of unconfined capacity."
~ Tsoknyi Rinpoche
