2) The essence of the Milindapañhā shows six parts of the text as follows: 1) former actions of the Nagasena and Milinda; 2) one class question; 3) two class question; 4) knowing by inference; 5) characteristics of dhammas; 6) knowing by analogy. The essence of the Milindapañhā related to the ultimate realities (paramattha-dhamma) including consciousness, mental factors, form and nirvana appears in the form of indirect questions and answers between Milinda and Nagasena.
