Study the teachings of the pine tree, the bamboo, and the plum blossom. The pine is evergreen, firmly rooted, and venerable. The bamboo is strong, resilient, unbreakable. The plum blossom is hardy, fragrant, and elegant.
A mind to serve for the peace of all human beings in the world is needed in Aikido, and not the mind of one who wishes to be strong or who practices only to fell an opponent.
