At Sāvatthī. Seated to one side, that mendicant said to the Buddha: “Sir, they speak of a ‘Dhamma speaker’. How is a Dhamma speaker defined? How is a mendicant who practices in line with the teaching defined? And how is a mendicant who has attained extinguishment in this very life defined?” “Mendicant, if a mendicant teaches Dhamma for disillusionment, dispassion, and cessation regarding form, they’re qualified to be called ‘a mendicant who speaks on Dhamma’. If they practice for disillusionment, dispassion, and cessation regarding form, they’re qualified to be called ‘a mendicant who practices in line with the teaching’. If they’re freed by not grasping by disillusionment, dispassion, and cessation regarding form, they’re qualified to be called ‘a mendicant who has attained extinguishment in this very life’. If a mendicant teaches Dhamma for disillusionment with feeling … perception … choices … consciousness, for its fading away and cessation, they’re qualified to be called ‘a mendicant who speaks on Dhamma’. If they practice for disillusionment, dispassion, and cessation regarding consciousness, they’re qualified to be called ‘a mendicant who practices in line with the teaching’. If they’re freed by not grasping by disillusionment, dispassion, and cessation regarding consciousness, they’re qualified to be called ‘a mendicant who has attained extinguishment in this very life’.”
