[160] How is it that wisdom (paññā) in defining internally (ajjhattavavatthāna) is knowledge of the diversity of bases (vatthunānatte ñāṇaṃ)? How does one define dhammas internally? One defines the eye (cakkhu) internally; one defines the ear internally; one defines the nose internally; one defines the tongue internally; one defines the body internally; one defines the mind internally.
