Arjuna asks, For the one with steady wisdom, i.e. the one who has a steady mind which is established in the Supreme Brahman, how does that person express?  What words does he use? How does he communicate with others? What is the nature of the absorbtion of the mind O Keshava? How does he talk? How does he walk? How does he sit and how does he move?
Through this question, Arjuna is actually asking about the qualities of a person of steady wisdom.
Avatarika: The one who has from the beginning, given up actions and are engaged in Karma yoga too, for those two types of people who are shown the means of practice by knowing the qualities of the man of steady wisdom, beginning from the verse, ‘Prajahati,’ until the end of the second chapter.
