心心相印

Pronunciation: xīn xīn xiāng yìn Literal meaning: Heart and heart mutually seal

Origin & Usage

This idiom describes hearts (心心) mutually (相) sealing or imprinting upon (印) each other. It comes from Chan (Zen) Buddhism describing the wordless transmission of understanding between master and disciple. The phrase evolved to describe perfect mutual understanding in any close relationship. Modern usage describes deep rapport where communication transcends words, often in romantic partnerships, close friendships, or mentor relationships.
