觸思識三食者，觸謂三和生觸，思謂意業，識謂識蘊，皆能持身，并稱為食。

'Contact, volition, and consciousness are three foods': contact refers to contact born from the conjunction of the three; volition refers to mental action; consciousness refers to the aggregate of consciousness. All are capable of sustaining the body, and are collectively called food.
