Today a poem by Kath Walker, aka Oodgeroo Noonuccal, (1920-1993), Australian poet and civil rights activist, and someone my grandmother knew.  Ms Walker was the first person of Australian Aboriginal descent to publish a book of poetry.

Song
Life is ours in vain
Lacking love, which never
Counts the loss or gain.
But remember, ever
Love is linked with pain.
Light and sister shade
Shape each mortal morrow
Seek not to evade
Love’s companion Sorrow,
And be not dismayed.
Grief is not in vain
It’s for our completeness
If the fates ordain
Love to bring life sweetness,
Welcome too its pain.
