noun
spiritual exchange; heart-to-heart communication; mutual understanding
Refers to a deep, non-verbal connection or emotional bond between people, often beyond mere words.
言葉が通じなくても、心の交流は可能だ。
Even without a common language, a spiritual exchange is possible.
彼女との心の交流が、私の人生を豊かにした。
The heart-to-heart connection with her enriched my life.
A set phrase meaning 'telepathy' or 'tacit understanding,' often used in Zen contexts; 心の交流 is broader and less idiomatic.
Compound of 心 (こころ, 'heart, mind') + の (possessive particle) + 交流 (こうりゅう, 'exchange, interchange'). The phrase is transparent and likely a modern coinage.
