Haragei (腹芸): https://en.wikipedia.org/wiki/Haragei #Mindful
A Japanese concept of interpersonal communication. Literally translated, the term means "stomach art", and it refers to an exchange of thoughts and feelings that is implied in conversation. It is a form of rhetoric intended to express real intention and true meaning through implication. Takie Lebra identified four dimensions of Japanese silence - truthfulness, social discretion, embarrassment and defiance. Information is communicated through timing, facial expression and emotional context, rather than through direct speech. Haragei also functions as a method of leadership, replacing direct orders to subordinates with subtle, non-verbal signals. In martial arts, haragei refers to those arts which supposedly enable the practitioner to sense threats or anticipate an opponent's movements.
