It is in this way, too, that nibbāna is directly visible.
“When, brahmin, one experiences the remainderless destruction of lust, the remainderless destruction of hatred, and the remainderless destruction of delusion, it is in this way, too, that nibbāna is directly visible, immediate, inviting one to come and see, applicable, to be personally experienced by the wise.”
“Excellent, Master Gotama! … Let Master Gotama consider me a lay follower who from today has gone for refuge for life.”
