For an immoral person, for one deficient in virtuous behavior, right concentration lacks its proximate cause

The Buddha's words

Dussīlasutta AN 5.24 https://suttacentral.net/an5.24

“Bhikkhus, for an immoral person, for one deficient in virtuous behavior, right concentration lacks its proximate cause. When there is no right concentration, for one deficient in right concentration, the knowledge and vision of things as they really are lacks its proximate cause. When there is no knowledge and vision of things as they really are, for one deficient in the knowledge and vision of things as they really are, disenchantment and dispassion lack their proximate cause. When there is no disenchantment and dispassion, for one deficient in disenchantment and dispassion, the knowledge and vision of liberation lacks its proximate cause.

“Suppose there is a tree deficient in branches and foliage. Then its shoots do not grow to fullness; also its bark, softwood, and heartwood do not grow to fullness. So too, for an immoral person, one deficient in virtuous behavior, right concentration lacks its proximate cause. When there is no right concentration, for one deficient in right concentration, the knowledge and vision of things as they really are lacks its proximate cause. When there is no knowledge and vision of things as they really are, for one deficient in the knowledge and vision of things as they really are, disenchantment and dispassion lack their proximate cause. When there is no disenchantment and dispassion, for one deficient in disenchantment and dispassion, the knowledge and vision of liberation lacks its proximate cause.

“Bhikkhus, for a virtuous person, for one whose behavior is virtuous, right concentration possesses its proximate cause. When there is right concentration, for one possessing right concentration, the knowledge and vision of things as they really are possesses its proximate cause. When there is the knowledge and vision of things as they really are, for one possessing the knowledge and vision of things as they really are, disenchantment and dispassion possess their proximate cause. When there is disenchantment and dispassion, for one possessing disenchantment and dispassion, the knowledge and vision of liberation possesses its proximate cause.

“Suppose there is a tree possessing branches and foliage. Then its shoots grow to fullness; also its bark, softwood, and heartwood grow to fullness. So too, for a virtuous person, one whose behavior is virtuous, right concentration possesses its proximate cause. When there is right concentration, for one possessing right concentration, the knowledge and vision of things as they really are possesses its proximate cause. When there is the knowledge and vision of things as they really are, for one possessing the knowledge and vision of things as they really are, disenchantment and dispassion possess their proximate cause. When there is disenchantment and dispassion, for one possessing disenchantment and dispassion, the knowledge and vision of liberation possesses its proximate cause.
