Why is surrender so great?

Why is surrender so great?

Surrender is great
Because it accepts
    Cheerfully
What it does not understand
    Remotely.

Also,
It does not care to understand
    Vaguely
anything whatsoever.
It only believes and obeys,
    And
Obeys and believes.

Surrender is by far the greatest
    Because it alone is the glowing ascent
    Of the aspiring heart
    And
    The proud descent
    Of the Absolute.
