Be thankful for your mistakes, failures, and blunders.
They are your own teacher reminding you of the middle and correct way.
Be mindful of your shortcomings. Just as you have them so do others. Treat your own mistakes and those of others with kindness.
The path of the warrior is the path of everyone. The landscape of the mind and everyday life is a battle.
Allies and enemies are borne in the mind. Be accepting but do not be blind.
In our school there is a saying; charge into the day at first light and do your best. Try not to stumble on the same stone in the road every day. Do not blame others when you do. Do not allow yourself to wallow in rinne 輪廻 (samsara). Be thankful for your mistakes, they are stepping stones from the ocean of ku 苦 (suffering).
