This is an time lost DA sūtra, most likely from Sautrantikas and/or Mulasarvastivadas.
The text bears striking resemblance to Mahāyāna literature, some formulas appearing almost verbatim in Lotus Sūtra, by Chadrakirti, etc.
Here’s Gleb S’s translation (from his amazing work) and the Sanskrit original. I’d be interested in hearing your thoughts 
Below you will find the reconstructed Sanskrit text and the English translation of the first of the six nearly identical portions of the sūtra (starts with the § 3.x, the §§ 1 and 2 represent the opening passages that are not repeated. This numeration is taken from the edition of the Tibetan text by P. Skilling (Skilling 1994: 3-57)). The six nearly identical parts are different only in that they are devoted to the different sense-objects (forms, sounds, smells, tastes, tangibles and dharmas) and each of the six parts uses its own pair of similes, which are listed at the respective paragraphs in the present text.

In Śrāvasti.
- There is, monks, training in higher conduct that is not accompanied by a higher mind and higher insight.
- There is training in higher conduct that is accompanied by a higher mind but lacks higher insight.
For a noble disciple, that dwells well-engaged in [the practice of] higher insight, the training in higher conduct and the higher mind comes to the fulfilment of/by cultivation.
Thus, here, monks, a noble disciple that dwells well-engaged in [the practice of] higher insight lives unsurpassed among those who live the life of/by insight.
And, how, monks, does a noble disciple that dwells well-engaged in [the practice of] the higher insight live unsurpassed among those who live the life of insight?
Here, monks, a noble disciple reflects in this way:
“Indeed, I should not now train with regard to the forms recognizable by the eye in this way, as I did before:
- Previously I dwelt pleased with regard to the forms recognizable by the eye which cause joy/pleasurable mental feeling.
- Previously I dwelt averse with regard to the forms recognizable by the eye which cause dejection.
- Previously I dwelt utterly inadvertently idle with regard to the forms recognizable by the eye which cause neutrality.
That is how for a long time for me, acting accordingly, following [that], there was no known beginning of experiencing old age and death.
Whatever there are for me with regard to the forms recognizable by the eye of the past, present and future, wrong affirmations or inversions of perception or inversions of mind or inversions of views, that is:
- the bodily tie of covetousness
- the bodily tie of enmity
- the bodily tie of adherence to rites and rituals
- the bodily tie of holding fast to and adhering to [the view] “this is the truth”,
are to be abandoned.
For their abandonment there should be the [following] training done.
Yet, here, for someone the forms recognizable by the eye [that] are agreeable, exactly they [are] disagreeable.
- Since this is so, at one time they cause joy.
- At another time they cause dejection.
- At another time they cause neutrality.
Thus there for a long time beings [that are] hindered by [their] mind, tricked by [their] mind, deceived by [their] mind, not seeing the danger, not aware of the escape, are at Māraʼs disposal.
Whatever, monks, ascetics or brāhmaṇas these forms recognizable by the eye truly and reliably do not realize, according to their very own wrong affirmations they, having seized tenaciously and adhering thereto, insist “this alone is the truth, everything else is ignorance”; they dwell pleased with regard to the forms recognizable by the eye which lead to joy.
Corrupted by the bodily tie of covetousness, those venerable ascetics and brāhmaṇas being tied by the fetter of enjoyment are at Māraʼs disposal.
Whatever, monks, ascetics or brāhmaṇas, these forms recognizable by the eye truly and reliably do not realize, according to their very own wrong affirmations they, having seized tenaciously and adhering thereto, insist: “this alone is the truth, everything else is ignorance”; they dwell averse with regard to those forms recognizable by the eye that lead to dejection.
Corrupted by the bodily tie of enmity, those venerable ascetics and brāhmaṇas being tied by the fetter of repugnance are at Māra’s disposal.
Whatever, monks, ascetics or brāhmaṇas, these forms recognizable by
the eye truly and reliably do not realize, according to their very own wrong affirmations they, having seized tenaciously and adhering thereto, insist: “this alone is the truth, everything else is ignorance”; they dwell inadvertently idle with regard to those forms recognizable by the eye which lead to neutrality.
Corrupted by the bodily tie of holding fast to and adhering to [the view] “this is the truth”, those venerable ascetics and brāhmaṇas being tied by the fetter of repugnance are at Māra’s disposal.
It is like, monks, if:
- An insane, mentally deranged person, may roam here and there and, rejoicing in that, he may not see any fault/danger in that.
- A man heavily intoxicated with alcohol mistakes his mother for another woman and has sex with her.
- A man does not realize, that his enemies are secretly approaching to hurt him, until it is too late.
- A disciple does not realize, that he mistakenly prepared cow dung and urine for his teacher’s meal.
- A man urgently fleeing the village attacked by brigands mistakenly takes with him another man’s son.
- A man fleeing a burning house takes with him a casket with the snake(s) / snake skin, having mistaken it for a casket with jewellery.
If he may regain his consciousness, he may exceedingly regret, may be ashamed of, may deject, may loathe his previous naked acting, acting in an insane way, acting out of his mind.
In this very way a noble disciple, having obtained exactly this noble supramundane insight, exceedingly regrets, is ashamed of, dejects, loathes that previous naked behavior, deluded behavior, [mentally] dull behavior.
That occurs to him: “I am; previously, I, while, indeed, being impermanent was thinking: I am permanent; while, indeed, being miserable was thinking: I am happy; while, indeed, being unclean/dirty was thinking: I am clean; while, indeed, being selfless was thinking: I am a self. Before I perceived permanence in impermanence, pleasure in suffering, cleanliness in unclean, self in not-self”.
It is as if:
- A skilled magician or a student of his, standing on the intersection of four big roads, were to show a four-form magical deed. That is: an army of elephants, cavalry, an army of chariots, infantry.
- Thunder creates echo in the mountain water channels.
- A person that has never before seen their reflection in a round (iron) mirror
- Mirage appears on a dry day in a desert.
- Objects and persons in sleep.
- A magician creates an illusion of beautiful ornaments made of jewellery and gems.
Here there are beings that are of foolish nature, of deluded nature, mentally dull ones, who think: “there is truly and reliably an army of elephants, cavalry, an army of chariots, infantry that is seen.” … etc.
However there are those beings that are not of foolish nature, not of deluded nature, the bright ones, who think: “there is not truly and reliably an elephant army, cavalry, army of chariots or infantry, that is seen – but that is indeed a magical creation, a delusion of the eye.” … etc.
In this very way a noble disciple reflects thus: “to me, in whatever forms recognizable by the eye of the past, present and future there is no permanency or stability or eternity or thusness or non-not-thusness or non-other-thusness or reality or truth-ness or true existence or according-ness or non-perversion or non-distortedness.
The supramundane truth of nobles, uttered by the bhagavat — this is indeed empty, this is indeed void, this is indeed without substance, this is indeed faulty, this is indeed of deceitful nature, this is indeed Māra, this is indeed an implement of Māra, this is indeed a corpse, this is indeed corpse-like, this is not worth relishing, asserting, remaining clung to, being clung to, staying [with].
He, having known thus, the forms recognizable by the eye of the past, future and present perceives as a disease, perceives [them] as a boil, as a dart, as a calamity, as impermanent, as painful, as empty, as not-self.
He has perceived the forms recognizable by the eye of the past, future and present as a disease, has perceived [them] as a boil, as a dart, as a calamity, as impermanent, as painful, as empty, as not-self.
Whatever are there, to him, with regard to the forms recognizable by the eye of the past, present and future, wrong affirmations or inversions of perception or inversions of mind or inversions of views, that is: the bodily tie of covetousness, the bodily tie of enmity, the bodily tie of adherence to the rites and rituals, the bodily tie of holding fast to and adhering to [the view] “this only is the truth”, they are abandoned.
Because of abandonment of those, having made Māra blind, he dwells not liable to despair, invisible to Māra the Evil One. Having killed Māra and his retinue, having fought a great battle, he has won the battle – that is how he dwells, having breached the frontline of the enemy army.
It is truly thus, monks, [how] a noble disciple, that dwells well-engaged in [the practice of] the higher insight, lives unsurpassed among those who live the life of insight.
