Kuai = Breakthrough

Then, out of nowhere, sudden certainty;
A confident conviction fills the air.
You had been hanging back, but now you dare
To take decisive action; you feel free,
Though sensing you could do no differently.
Your gait embodies unselfconscious flare,
That naturally the others want to share,
They join in eager unanimity.

In time is metamorphosis compressed.
A line divides the future from the past,
As past the river’s rambling you can see
An occult energy there manifest;
And all the universe erupts in vast,
Uncontemplated possibility.
