Ishin-denshin (以心伝心) is a Japanese idiom meaning "what the heart feels, the mind transmits," referring to tacit, nonverbal communication or "heart-to-heart" understanding. It implies a deep, unspoken connection between people where emotions or thoughts are understood without words, often described as a form of "telepathy" or mutual understanding. | Bushinden Tasmania Toku Bu Ryū Sui Budō Dōjō 武神傳徳武流水武道道場
