[597] "And how, bhikkhus, is the liberation of mind (cetovimutti) by loving-kindness developed? What is its destination, what is its culmination, what is its fruit, what is its final goal? Here, bhikkhus, a bhikkhu develops the mindfulness factor of awakening (satisambojjhaṅga) accompanied by loving-kindness … he develops the equanimity factor of awakening (bojjhaṅga) accompanied by loving-kindness, based upon seclusion (viveka), based upon dispassion (virāga), based upon cessation, maturing in relinquishment (vossagga). If he wishes: 'May I dwell perceiving the repulsive in the unrepulsive,' he dwells therein perceiving the repulsive. If he wishes: 'May I dwell perceiving the unrepulsive in the repulsive,' he dwells therein perceiving the unrepulsive. If he wishes: 'May I dwell perceiving the repulsive in both the unrepulsive and the repulsive,' he dwells therein perceiving the repulsive. If he wishes: 'May I dwell perceiving the unrepulsive in both the repulsive and the unrepulsive,' he dwells therein perceiving the unrepulsive. If he wishes: 'Avoiding both the unrepulsive and the repulsive, may I dwell equanimous, mindful and clearly comprehending,' he dwells therein equanimous, mindful and clearly comprehending. Or else he enters and dwells in the beautiful liberation (subha vimokkha). Bhikkhus, I declare the liberation of mind by loving-kindness to have the beautiful as its culmination — for a wise bhikkhu here who has not penetrated to a higher liberation.
