In Chinese and Korean, this means “simplicity heart,” “composure,” “calmness,” or a “sense of orderliness.” In Chinese and Korean, this implies that you enjoy what you have, keep your heart in balance, and have no over-blown ambitions.

身心霊 means “body mind spirit” in Japanese.

This refers to your physical, mental, and spiritual presence.

This can also be translated as “body heart spirit” as 心 can mean mind or heart.

Note that this is a "word list" and not a proper phrase (with a subject, verb, and object) nor a typical title in Japanese. So it's not too commonly seen in Japan. However, the term 身心霊整合性医療 that refers to holistic medicine is gaining popularity.
