[24] "Bhikkhus, for one who is immoral, whose virtue is corrupted, right concentration (sammāsamādhi) has its proximate cause (upanisā) destroyed. When there is no right concentration, for one whose right concentration is corrupted, knowledge and vision of things as they really are (yathābhūtañāṇadassana) has its proximate cause destroyed. When there is no knowledge and vision of things as they really are, for one whose knowledge and vision of things as they really are is corrupted, disenchantment and dispassion (nibbidāvirāga) have their proximate cause destroyed. When there is no disenchantment and dispassion, for one whose disenchantment and dispassion are corrupted, knowledge and vision of liberation (vimuttiñāṇadassana) has its proximate cause destroyed.
"Suppose, bhikkhus, there were a tree deficient in branches and foliage: its shoots do not grow to fullness, its bark does not grow to fullness, its softwood does not grow to fullness, and its heartwood does not grow to fullness. Just so, bhikkhus, for one who is immoral, whose virtue is corrupted, right concentration has its proximate cause destroyed. When there is no right concentration, for one whose right concentration is corrupted, knowledge and vision of things as they really are has its proximate cause destroyed. When there is no knowledge and vision of things as they really are, for one whose knowledge and vision of things as they really are is corrupted, disenchantment and dispassion have their proximate cause destroyed. When there is no disenchantment and dispassion, for one whose disenchantment and dispassion are corrupted, knowledge and vision of liberation has its proximate cause destroyed.
"But, bhikkhus, for one who is virtuous, accomplished in virtue, right concentration is endowed with its proximate cause. When there is right concentration, for one accomplished in right concentration, knowledge and vision of things as they really are is endowed with its proximate cause. When there is knowledge and vision of things as they really are, for one accomplished in knowledge and vision of things as they really are, disenchantment and dispassion are endowed with their proximate cause. When there is disenchantment and dispassion, for one accomplished in disenchantment and dispassion, knowledge and vision of liberation is endowed with its proximate cause.
