Āyatana are entrances for producing cognition. This can be divided into two categories, the inner entrances and the outer entrances (ālambana - object of support) in pairs. In general, this refers to the most common 12-entrances(dvādaśāyatanāni) list of kāmadhātu model of existence.

There are several types of inner and outer entrances. Inner entrances pairs with the corresponding outer entrances based on the characteristics of cognition. For example, inner eye entrance pairs with object of form for form cognition (or simply what we call seeing), and mind entrance pairs with mind object(dharmāyatana) or roughly "thought or idea" for mental cognition, etc.
