A class of devas born in the Realm of Infinite Space (ákásánañcáyatana) (M.iii.103).
They belong to the Arúpa world and their life term is twenty thousand kappas (A.i.267; AbhS., p.23).
Their mind arises and ceases moment by moment (Kvu.i.207-8).
In the description of the Arúpávacarabhúmi, these devas represent the lowest limit, the highest being the Nevasaññánásaññá. Ps.i.84.
