Kaibara Ekiken, an Edo-period herbalist, wrote in his book “Yojokun” that the natural state of man is to maintain the harmony of mind and body.
Hard branches will break.
Be flexible and bend well.
It is not how strong you are but how resilient you are.
To guide yourself for the equanimity of mind and body.
Listen carefully to your body’s voice.
Take care of yourself daily.
