The Discourse on Tikaṇḍakī
144.
On one occasion the Blessed One was dwelling at Sāketa in the Tikaṇḍakī Grove.
There the Blessed One addressed the monks thus:
"Monks."
"Venerable sir," those monks assented to the Blessed One.
The Blessed One said this:
"Good, monks, a monk should from time to time dwell perceiving the repulsive in the non-repulsive. Good, monks, a monk should from time to time dwell perceiving the non-repulsive in the repulsive. Good, monks, a monk should from time to time dwell perceiving the repulsive in both the non-repulsive and the repulsive. Good, monks, a monk should from time to time dwell perceiving the non-repulsive in both the repulsive and the non-repulsive. Good, monks, a monk should from time to time, having avoided both the repulsive and the non-repulsive, dwell equanimous, mindful and fully aware.
"And what, monks, is the reason dependent on which a monk should dwell perceiving the repulsive in the non-repulsive? 'May lust not arise in me towards enticing mental states' - this, monks, is the reason dependent on which a monk should dwell perceiving the repulsive in the non-repulsive.
"And what, monks, is the reason dependent on which a monk should dwell perceiving the non-repulsive in the repulsive? 'May hate not arise in me towards mental states based on hate' - this, monks, is the reason dependent on which a monk should dwell perceiving the non-repulsive in the repulsive.
"And what, monks, is the reason dependent on which a monk should dwell perceiving the repulsive in both the non-repulsive and the repulsive? 'May lust not arise in me towards enticing mental states, may hate not arise in me towards mental states based on hate' - this, monks, is the reason dependent on which a monk should dwell perceiving the repulsive in both the non-repulsive and the repulsive.
"And what, monks, is the reason dependent on which a monk should dwell perceiving the non-repulsive in both the repulsive and the non-repulsive? 'May hate not arise in me towards mental states based on hate, may lust not arise in me towards enticing mental states' - this, monks, is the reason dependent on which a monk should dwell perceiving the non-repulsive in both the repulsive and the non-repulsive.
"And what, monks, is the reason dependent on which a monk, having avoided both the repulsive and the non-repulsive, should dwell equanimous? 'Mindful and fully aware, may lust not arise in me anywhere, in any place, in any way towards enticing mental states; may hate not arise in me anywhere, in any place, in any way towards mental states based on hate; may delusion not arise in me anywhere, in any place, in any way towards mental states leading to infatuation' - this, monks, is the reason dependent on which a monk, having avoided both the repulsive and the non-repulsive, should dwell equanimous, mindful and fully aware." The fourth.
