If men keep killing fellow-men on earth
In wars that leaders start without reason,
God will deny through Nature any mirth,
And teach the human race, a good lesson!

What right has man to destroy human life?
God gave a soul to everyone by love;
He helps the human beings in all strife;
He cares for them forever from above!

All senseless killings ought to stop at once;
The wrath of God is more than Nature’s rage;
No lasting peace can be ushered by guns!
Each man must try to live akin a sage.

When sun, wind, rain can destroy man with ease,
All tendencies to kill by man must cease!

Dr John Celes
