The Discourse on Restraint of the Faculties
50.
"When sense restraint is absent, monks, for one failing in sense restraint, morality has its proximate cause destroyed;
when morality is absent, for one failing in morality, right concentration has its proximate cause destroyed;
when right concentration is absent, for one failing in right concentration, knowledge and vision of things as they really are has its proximate cause destroyed;
when knowledge and vision of things as they really are is absent, for one failing in knowledge and vision of things as they really are, disenchantment and dispassion has its proximate cause destroyed;
when disenchantment and dispassion is absent, for one failing in disenchantment and dispassion, knowledge and vision of liberation has its proximate cause destroyed.
Just as, monks, a tree lacking branches and leaves.
Its outer bark does not go to fulfilment, its inner bark does not go to fulfilment, its softwood does not go to fulfilment, its heartwood does not go to fulfilment.
So too, monks, when sense restraint is absent, for one failing in sense restraint, morality has its proximate cause destroyed... etc.
knowledge and vision of liberation.
"When sense restraint is present, monks, for one accomplished in sense restraint, morality is accomplished in its proximate cause; when morality is present, for one accomplished in morality, right concentration is accomplished in its proximate cause; when right concentration is present, for one accomplished in right concentration, knowledge and vision of things as they really are is accomplished in its proximate cause; when knowledge and vision of things as they really are is present, for one accomplished in knowledge and vision of things as they really are, disenchantment and dispassion is accomplished in its proximate cause; when disenchantment and dispassion is present, for one accomplished in disenchantment and dispassion, knowledge and vision of liberation is accomplished in its proximate cause. Just as, monks, a tree accomplished with branches and leaves. Its outer bark goes to fulfilment, its inner bark goes to fulfilment, its softwood goes to fulfilment, its heartwood goes to fulfilment. So too, monks, when sense restraint is present, for one accomplished in sense restraint, morality is accomplished in its proximate cause... etc. knowledge and vision of liberation." The eighth.
