4.443

Because contaminated contact, the moment it contacts an object, takes in joy and pleasure, it can perform the function of food. That is, being able to nourish, produce, and grow feelings of joy, pleasure, and equanimity, causing them to increase and benefit the body, it is called food. Is the contact concomitant with all eight consciousnesses food?
