Origin

This character pictures a person (the left side suggests a human form) deep inside an enclosed space or room (the right side shows enclosure). The idea of being tucked far back inside a confined area came to represent the interior or innermost part of something—whether a physical space like the back of a house, or a more abstract sense of the heart or core of a matter. The character's shape originally captured that sense of depth and hiddenness that goes with these meanings.
