20.     Ajjhatta Tika:

        (iii)  (1052).    What are the dhamma which are internal and external?
                                  
        There are dhamma (i.e, the five aggregates) which are internal (i.e, in oneself) and external (i.e, in others).
        ~These are the dhamma which are internal and external.

       
        (iii)  (1435).   
      
        Leaving aside Corporeality which does not have any faculties and  Nibbana, all the remaining dhamma are the dhamma which sometimes arise internally, which sometimes arise externally and which sometimes arise both internally and externally.
        Corporeality which does not have any faculties and Nibbana are the dhamma which arise externally
