Catastrophe/Apostrophe: The Buddha’s Teachings on Dependent Origination/Cessation

The subject of dependent origination is intrinsically rich and varied, subtle and multi-dimensional, as the Buddha expressed in this notable exchange with his disciple and attendant Ven. ?nanda:

Thus have I heard. On one occasion the Blessed One was living among the Kurus, near a town of theirs named Kamm?sadhamma. There Ven. ?nanda approached the Blessed One and, on arrival, having bowed down to the Blessed One, sat to one side. As he was sitting there he said to the Blessed One: ?It?s wonderful, venerable sir, it?s marvellous, how profound this dependent origination is, and how profound its appearance, and yet to me it appears as clear as clear can be.?
?Do not say that, ?nanda! Do not say that! This dependent origination is profound and it appears profound. It is through not understanding and not penetrating this Dhamma that this generation has become like a tangled ball of string, matted like a bird?s nest, tangled like coarse grass and is unable to pass beyond the cycles of rebirth, beyond the planes of deprivation, woe and bad destinations.?
(D 15.1)
