[645] What is internal emptiness (ajjhattasuñña)? Internally the eye (cakkhu) is empty of self, of what belongs to self, of what is permanent, of what is lasting, of what is eternal, or of what is of an unchanging nature. Internally the ear is empty … Internally the nose is empty; internally the tongue is empty; internally the body is empty; internally the mind is empty of self, of what belongs to self, of what is permanent, of what is lasting, of what is eternal, or of what is of an unchanging nature. This is internal emptiness.
