Poem: Egrets (which sounds like Regrets)

Egrets

Once as I travelled through a quiet evening,
I saw a pool, jet-black and mirror-still.
Beyond, the slender paperbarks stood crowding;
each on its own white image looked its fill,
and nothing moved but thirty egrets wading -
thirty egrets in a quiet evening.

Once in a lifetime, lovely past believing,
your lucky eyes may light on such a pool.
As though for many years I had been waiting,
I watched in silence, till my heart was full
of clear dark water, and white trees unmoving,
and, whiter yet, those thirty egrets wading.

-- Judith Wright, Birds (1962), aka Thirty Egrets Wading
