以心伝心
Ishin denshin（以心伝心）is a Japanese four-character idiom, or yojijukugo, that literally means "transmitting the heart, by the heart." It describes an understanding that needs no words — a feeling that passes between two people in silence, received before it is ever spoken. The phrase originated in Zen Buddhism, where the deepest truth was said to be handed down not through scripture or sermon, but directly from a master's mind to a disciple's. It is used today in Japanese to describe couples, old friends, and teammates so attuned that a single glance says everything.
