[119] Therein, what is the space element (ākāsadhātu)?
The space element is twofold: there is the internal; there is the external.
Therein, what is the internal space element?
That which internally, belonging to oneself, is space, what is reckoned as space, void, what is reckoned as void, a gap, what is reckoned as a gap, not touched by flesh and blood, internal, clung-to (upādinna) — namely: the orifice of the ear, the orifice of the nose, the door of the mouth, that whereby one swallows what is eaten, drunk, chewed, and tasted, that wherein what is eaten, drunk, chewed, and tasted remains, and that whereby what is eaten, drunk, chewed, and tasted passes out below; or whatever else there is internally, belonging to oneself, that is space, what is reckoned as space, void, what is reckoned as void, a gap, what is reckoned as a gap, not touched by flesh and blood, internal, clung-to — this is called the internal space element.
Therein, what is the external space element?
That which externally is space, what is reckoned as space, void, what is reckoned as void, a gap, what is reckoned as a gap, not touched by the four primary elements (mahābhūta), external, not clung-to — this is called the external space element.
The internal space element and the external space element — gathering these together and combining them as one — this is called the space element.
