Dr. Gethin in his book (The Buddhist Path to Awakening, p. 278) uses the term 'Maatikaa' to refer to the topics in all Pali Abhidhammas. As Nina indicated before that the term Maatikaa is shown in the Dhamma-sangani. Is the term Maatikaa also allowed to use in other Abhidhammas (and Suttas) in the Pali tradition?
