In zen teaching, shujinko means “true self.” So how can we find our “true self”?
無想 Muso: Don’t think anything, get rid of all thoughts
無念 Munen: Let go of desires, don’t get distracted by the stimulus from the outside world
無住 Muju: Let go of your attachment to material things
What remains is the “true self.” Zazen is the practice to help remove these noises and find “true self.”
