Blessings Be on Robert Burns

Here was I feeling angry and self-righteous when Robbie Burns reminded me of this:

Then gently scan your brother man,
Still gentler sister woman;
Tho' they may gang a kennin wrang,
To step aside is human;
One point must still be greatly dark,--
The moving Why they do it;
And just as lamely can ye mark,
How far perhaps they rue it.

Who made the heart, 'tis He alone
Decidedly can try us;
He knows each chord, its various tone,
Each spring, its various bias:
Then at the balance, let's be mute,
We never can adjust it;
What's done we party may compute,
But not know what's resisted.

And I am rightly schooled. Thank you, Rab.
