When Does the Heart Know? (a song)

When does the heart know,
the truth of white and clear?
When does the heart know
in the span of one short year?

When does the heart love,
when can it fly free?
When does the heart love,
or feel blind and can't see?

When does the heart cry,
when the levy fails to hold?
When does it meet winter sky
when does it feel so cold?

When does the heart ask,
as though a small child?
when does the heart ask
with peace which only smiled?

How does the heart heal
as day spins into day?
How does the heart heal
makes its courageous way?

I thought the heart knew,
but time would tell true,
some things we can't know,
and some hearts must go.
