Calligraphy hanging in our sangha room is a gift from Enraky-ji Temple’s Ven. Kobori Kojitsu for Shingaku’s formal tokudo ceremony.

“尽 ‐zin” means to do one’s best or devote oneself into something
“真‐shin” means truth or real
“心‐shin” means heart or mind

Devote yourself from the bottom of your heart.
Have kindness and warmth in your actions, attitude, and words.
