Dependent origination

"There is the case where a disciple of the noble ones notices:

"When this is, that is.
From the arising of this comes the arising of that.
When this isn't, that isn't.
From the cessation of this comes the cessation of that."

In other words:

From ignorance as a requisite condition come fabrications.
From fabrications as a requisite condition comes consciousness.
From consciousness as a requisite condition comes name-&-form.
From name-&-form as a requisite condition come the six sense media.
From the six sense media as a requisite condition comes contact.
From contact as a requisite condition comes feeling.
From feeling as a requisite condition comes craving.
From craving as a requisite condition comes clinging/sustenance.
From clinging/sustenance as a requisite condition comes becoming.
From becoming as a requisite condition comes birth.
From birth as a requisite condition, then aging & death, sorrow, lamentation, pain, distress, & despair come into play. Such is the origination of this entire mass of stress & suffering.

Now from the remainderless fading & cessation of that very ignorance comes the cessation of fabrications. From the cessation of fabrications comes the cessation of consciousness. From the cessation of consciousness comes the cessation of name-&-form. From the cessation of name-&-form comes the cessation of the six sense media. From the cessation of the six sense media comes the cessation of contact. From the cessation of contact comes the cessation of feeling. From the cessation of feeling comes the cessation of craving. From the cessation of craving comes the cessation of clinging/sustenance. From the cessation of clinging/sustenance comes the cessation of becoming. From the cessation of becoming comes the cessation of birth. From the cessation of birth, then aging & death, sorrow, lamentation, pain, distress, & despair all cease. Such is the cessation of this entire mass of stress & suffering.

"This is the noble method that he has rightly seen & rightly ferreted out through discernment."

— AN 10.92

"When a disciple of the noble ones has seen well with right discernment this dependent co-arising & these dependently co-arisen phenomena as they have come to be, it is not possible that he would run after the past, thinking, 'Was I in the past? Was I not in the past? What was I in the past? How was I in the past? Having been what, what was I in the past?' or that he would run after the future, thinking, 'Shall I be in the future? Shall I not be in the future? What shall I be in the future? How shall I be in the future? Having been what, what shall I be in the future?' or that he would be inwardly perplexed about the immediate present, thinking, 'Am I? Am I not? What am I? How am I? Where has this being come from? Where is it bound?' Such a thing is not possible. Why is that? Because the disciple of the noble ones has seen well with right discernment this dependent co-arising & these dependently co-arisen phenomena as they have come to be."
