Violence

All tremble at violence,
Life is dear to all.
Comparing others with oneself
One should neither kill nor cause others to kill.

~Dhammapada v. 130

The first of the five fundamental Buddhist precepts is "Avoid killing any living thing."

War is one of the uttter ways of ignoring care and compassion.
But even those finding themselves taking part can change themselves.
There's always someone who can use support and care.

Often it's said that even buddhists have fought in wars.
But that's no reason at all to follow in their footsteps.
