If outer foes are destroyed while not subduing the enemy of one’s own hatred, enemies will only increase. Therefore, subduing one’s own mind with the army of love and compassion is the Bodhisattvas’ practice.
A bodhisattva’s practice is to tame our mental continuums
With the armed forces of love and compassion,
Because, if we haven’t subdued the enemy which is our own hostility,
Then even if we have subdued an external enemy, more will come.
