The deeper meaning of "simplicity" is not about external simplification, but about internal wisdom and awareness. Through focus, right thoughts, wisdom, and practice, one achieves the unity of body and mind, the harmony of movement and stillness, which is also the life attitude and practice goal pursued by diligent Zen practitioners.
"Contentment means accord with conditions" captures the essence of true adaptability. This is no aimless drifting but wise discernment of causes and circumstances—neither forcing outcomes nor resisting reality, until the undisturbed mind mirrors all phenomena without distortion, attaining that noble state where "freedom from want becomes one's true adornment."
