Most of the exlemplars of stream enterers you present in the paper would reject your definition of it.

It’s just as if a man, traveling along a wilderness track, were to see an ancient path, an ancient road, traveled by people of former times. He would follow it. Following it, he would see an ancient city, an ancient capital inhabited by people of former times, complete with parks, groves, & ponds, walled, delightful. He would go to address the king or the king’s minister, saying, ‘Sire, you should know that while traveling along a wilderness track I saw an ancient path.... I followed it.... I saw an ancient city, an ancient capital... complete with parks, groves, & ponds, walled, delightful. Sire, rebuild that city!’ The king or king’s minister would rebuild the city, so that at a later date the city would become powerful, rich, & well-populated, fully grown & prosperous.

In the same way I saw an ancient path, an ancient road, traveled by the Rightly Self-awakened Ones of former times. And what is that ancient path...? Just this noble eightfold path: right view, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, right concentration.... I followed that path. Following it, I came to direct knowledge of aging-&-death, direct knowledge of the origination of aging-&-death, direct knowledge of the cessation of aging-&-death, direct knowledge of the path leading to the cessation of aging-&-death. I followed that path. Following it, I came to direct knowledge of birth... becoming... clinging... craving... feeling... contact... the six sense media... name-&-form... consciousness, direct knowledge of the origination of consciousness, direct knowledge of the cessation of consciousness, direct knowledge of the path leading to the cessation of consciousness. I followed that path.

Before my self-awakening, when I was still just an unawakened Bodhisatta, the realization came to me: ‘How this world has fallen on difficulty! It is born, it ages, it dies, it falls away & rearises, but it does not discern the escape from this stress, from this aging-&-death. O when will it discern the escape from this stress, from this aging-&-death?’Then the thought occurred to me, ‘Aging-&-death exists when what exists? From what as a requisite condition is there aging-&-death?’ From my appropriate attention there came the breakthrough of discernment: ‘Aging-&-death exists when birth exists. From birth as a requisite condition comes aging-&-death.’ Then the thought occurred to me, ‘Birth exists when what exists? From what as a requisite condition comes birth?’ From my appropriate attention there came the breakthrough of discernment: ‘Birth exists when becoming exists. From becoming as a requisite condition comes birth.... ‘Name-&-form exists when what exists? From what as a requisite condition is there name-&-form?’ From my appropriate attention there came the breakthrough of discernment: ‘Name- &-form exists when consciousness exists. From consciousness as a requisite condition comes name-&-form.’ Then the thought occurred to me, ‘Consciousness exists when what exists? From what as a requisite condition comes consciousness?’ From my appropriate attention there came the breakthrough of discernment: ‘Consciousness exists when name-&-form exists. From name-&-form as a requisite condition comes consciousness.’Then the thought occurred to me, ‘This consciousness turns back at name-&- form, and goes no farther. It is to this extent that there is birth, aging, death, falling away, & re-arising, i.e., from name-&-form as a requisite condition comes consciousness, from consciousness as a requisite condition comes name-&-form. From name-&-form as a requisite condition come the six sense media.... Thus is the origination of this entire mass of stress. Origination, origination.’ Vision arose, clear knowing arose, discernment arose, knowledge arose, illumination arose within me with regard to things never heard before.Then the thought occurred to me, ‘Aging-&-death doesn’t exist when what doesn’t exist? From the cessation of what comes the cessation of aging-&-death?’ From my appropriate attention there came the breakthrough of discernment: ‘Aging-&-death doesn’t exist when birth doesn’t exist. From the cessation of birth comes the cessation of aging-&-death.’... ‘Name-&-form doesn’t exist when what doesn’t exist? From the cessation of what comes the cessation of name-&-form?’ From my appropriate attention there came the breakthrough of discernment: ‘Name-&-form doesn’t exist when consciousness doesn’t exist. From the cessation of consciousness comes the cessation of name-&-form.’ Then the thought occurred to me, ‘Consciousness doesn’t exist when what doesn’t exist? From the cessation of what comes the cessation of consciousness?’ From my appropriate attention there came the breakthrough of discernment: ‘Consciousness doesn’t exist when name-&-form doesn’t exist. From the cessation of name-&-form comes the cessation of consciousness.’The thought occurred to me, ‘I have attained this path to Awakening, i.e., from the cessation of name-&-form comes the cessation of consciousness, from the cessation of consciousness comes the cessation of name-&-form. From the cessation of name-&-form comes the cessation of the six sense media.... Thus is the cessation of this entire mass of stress. Cessation, cessation.’ Vision arose, clear knowing arose, discernment arose, knowledge arose, illumination arose within me with regard to things never heard before.It’s just as if a man, traveling along a wilderness track, were to see an ancient path, an ancient road, traveled by people of former times.

Knowing that directly, I have revealed it to monks, nuns, male lay followers, & female lay followers, so that this holy life has become powerful, rich, detailed, well- populated, wide-spread, proclaimed among celestial & human beings.

§ 234. ‘There are these four nutriments for the establishing of beings who have taken birth or for the support of those in search of a place to be born. Which four? Physical food, gross or refined; contact as the second, consciousness the third, and intellectual intention the fourth. These are the four nutriments for the establishing of beings or for the support of those in search of a place to be born.‘Where there is passion, delight, & craving for the nutriment of physical food, consciousness lands there and grows. Where consciousness lands and grows, name-&-form alights. Where name-&-form alights, there is the growth of fabrications. Where there is the growth of fabrications, there is the production of renewed becoming in the future. Where there is the production of renewed becoming in the future, there is future birth, aging, & death, together, I tell you, with sorrow, affliction, & despair.‘Just as—when there is dye, lac, yellow orpiment, indigo, or crimson—a dyer or painter would paint the picture of a woman or a man, complete in all its parts, on a well-polished panel or wall, or on a piece of cloth; in the same way, where there is passion, delight, & craving for the nutriment of physical food, consciousness lands there & grows... together, I tell you, with sorrow, affliction, & despair.[Similarly with the other three kinds of nutriment.]‘Where there is no passion for the nutriment of physical food, where there is no delight, no craving, then consciousness does not land there or grow.... Name-&- form does not alight.... There is no growth of fabrications.... There is no production of renewed becoming in the future. Where there is no production of renewed becoming in the future, there is no future birth, aging, & death. That, I tell you, has no sorrow, affliction, or despair.‘Just as if there were a roofed house or a roofed hall having windows on the north, the south, or the east. When the sun rises, and a ray has entered by way of the window, where does it land?’
‘On the western wall, lord.’
‘And if there is no western wall...?’ ‘On the ground, lord.’
‘And if there is no ground...?’
‘On the water, lord.’
‘And if there is no water...?’
‘It does not land, lord.’‘In the same way, where there is no passion for the nutriment of physical food...consciousness does not land or grow.... That, I tell you, has no sorrow, affliction, or despair.’[Similarly with the other three kinds of nutriment.]

§ 235. Consciousness without feature, without end,luminous all around:
Here water, earth, fire, & wind have no footing. Here long & shortcoarse & fine fair & foulname & form are, without remnant, brought to an end. From the cessationof (the activity of) consciousness, each is here brought to an end.

§ 236. Where water, earth, fire, & wind have no footing:There the stars don’t shine, the sun isn’t visible.There the moon doesn’t appear. There darkness is not found.And when a sage,
a brahman through sagacity, has realized (this) for himself,then from form & formless, from pleasure & pain,he is freed.

The ending of the effluents is for one who knows & sees, I tell you, not for one who does not know & does not see.

For one who knows what & sees what?... ‘Such is form, such its origination, such its disappearance. Such is feeling.... Such is perception.... Such are fabrications.... Such is consciousness, such its origination, such its disappearance.’ The ending of the effluents is for one who knows in this way & sees in this way. The knowledge of ending in the presence of ending has its prerequisite, I tell you. It is not without a prerequisite. And what is its prerequisite? Release...Release has its prerequisite, I tell you. It is not without a prerequisite. And what is its prerequisite? Dispassion.... Disenchantment.... Knowledge & vision of things as they have come to be.... Concentration.... Pleasure.... Calm.... Rapture.... Joy.... Conviction.... Stress.... Birth.... Becoming.... Clinging.... Craving.... Feeling.... Contact....The six sense media.... Name-&- form.... Consciousness.... Fabrications.... Fabrications have their prerequisite, I tell you. They are not without a prerequisite.

And what is their prerequisite? Ignorance....

Just as when the devas pour rain in heavy drops & crash thunder on the upper mountains: the water, flowing down along the slopes, fills the mountain clefts & rifts & gullies. When the mountain clefts & rifts & gullies are full, they fill the little ponds. When the little ponds are full, they fill the big lakes... the little rivers... the big rivers. When the big rivers are full, they fill the great ocean.

In the same way:

fabrications have ignorance as their prerequisite, consciousness has fabrications as its prerequisite, name-&-form has consciousness as its prerequisite,

the six sense media have name-&-form as their prerequisite, contact has the six sense media as its prerequisite,feeling has contact as its prerequisite,

craving has feeling as its prerequisite,

clinging has craving as its prerequisite,

becoming has clinging as its prerequisite,

birth has becoming as its prerequisite,

stress & suffering have birth as their prerequisite, conviction has stress & suffering as its prerequisite, joy has conviction as its prerequisite,

rapture has joy as its prerequisite,

calm has rapture as its prerequisite,

pleasure has calm as its prerequisite, concentration has pleasure as its prerequisite,

knowledge & vision of things as they have come to be has concentration as its prerequisite,

disenchantment has knowledge & vision of things as they have come to be as its prerequisite,

dispassion has disenchantment as its prerequisite, release has dispassion as its prerequisite, knowledge of ending has release as its prerequisite. SN 12:23

If we turn to classical early European mystical texts, such as those by late-antiquity author Plotinus, we find that they describe “mystical ascent”, the phases of which are described in Mazur (2021), as culminating in a total “annihilation” into the “One” called henosis (Greek for “union”), which is followed by a “desubjectification”. Similarly, the last stage of the “path to God” as described by 13th-century German Mystics like Meister Eckhart or his student Tauler, is called a “modeless good” (De Libera, 1996), referring not as much to an “experience” with specific phenomenal features, but as a going beyond all manifest appearances (including going beyond feelings of bliss, of sacredness, of unity, of transcendence, etc.). Early mystical theologies like that of 5th- or 6th-century church father pseudo-Dionysius the Areopagite (Luibheid and Rorem, 1987) — a ubiquitous influence on medieval contemplatives — and later ones such as that by St. John of the Cross (St. John of the Cross [2010]; Marler and Rorem [1996]), respectively describe unio mystica[33] as “an obscure and luminous darkness” and a “going forth from the flesh”. The same is true of other Abrahamic traditions, as described in Fisher (2022). All of these quintessentially mystical experiences seem to bear more resemblance with the Buddhist notion of “cessation of consciousness” than with Jamesian or Stacean “mystical experience”, which likely should be correlated with phenomena and experiences encountered at earlier phases of these developmental models. Note that in Theravada texts, even such “cessations of consciousness” are classified into various types depending on their setup, mode of entrance, and phenomena and effects after the exit.

In contemporary research, meditation practices are often divided into “constructive,” “attentional,” and “deconstructive” types (Dahl, 2015). Similarly, in their model for the cross-cultural analysis of altered-states of consciousness, anthropologists Locke and Kelly (1985) propose to regroup a variety of ASC-induction modalities into the category of “inversion procedures,” which is a broader category than the previous, but, taken, at the level of contemplative practices, corresponds to the deconstructive type (which includes e.g. vipāssana meditation). The “mystical” itinerary has even been termed “decreation” by Simone Weil (Carson, 2019), i.e. the reversal of the process of “creation.” Indeed, one of the most influential figures on European contemplatives since antiquity, Plotinus, “envisioned the final stages of mystical ascent to the One to be homologous to the process by which the Intellect first emerges from it,” and “ believed that the ultimate mystical union with the One (MUO) could be attained through the contemplative or visionary reiteration of the first reflexive moment of ontogenesis,” as quoted in Mazur (2021, chap. 4). Ontogenesis means the “coming-into-being” (genesis) of “beings,” or “things” (ontas). This notion can be directly related with the more recent concept of Emergence (Varela, 1992). If emergence (as we mean it) has something to do with the meditative deconstruction of the process of emergence (in the scientific sense of emergentism) of phenomena–beings, as is claimed here by Plotinus, then the semantic overlap is not just a fortuitous mishap, but reveals a direct connection between emergence, emergent phenomena and emergentism. This general semantic nexus is confirmed by other contemplative traditions — for instance, some buddhist mahamudra texts describe the process of ontogenesis as “co-emergence” (Ṅag-dbaṅ-kun-dgaʼ-bstan-ʼdzin and Abboud, 2014) and equate the fruit of meditative practice with the “realization” of, or direct insight into, this process of co-emergence, thereby presenting the result of the contemplative process — much like Plotinus did — as the experiential uniting of the direct perception of the metaphysical or cosmo-phenomenological process of phenomenalisation (Henry, 1973) with a process of psychological development achieved through intentional cultivation. In this perspective, what we call here the process of emergence — a developmental trajectory which an individual may go through — is thus in direct connection with the “ontological” or “phenomenological” process theorized by some cognitive scientists as emergence.
