Do not swear by your own head either.
Since you cannot turn a single hair white or black.
Our own anger can be a remorseless tether.
About this we just have to be frank.I was walking in the summer twilight.
All was deathly still .
The trees not moving in the yellowing light.
Calm, nothing shrill.

The long shadows.
The soft light.
Breathless breeze slows.
Dimming sight.

But a good feeling.
And happiness revealing.

…….

Do not swear by head
You cannot change  just one hair
You have what you have.

……..

See Matthew 5  33-37
