I was writing about “the seven (types of) persons existing in the world” mentioned in MN 70, and had occasion to look at MN 4.
The first “person” described in MN 70 was “freed both ways”. Although Gautama listed “abiding, having apprehended with the person those peaceful Deliverances which are incorporeal having transcended material shapes” (the arupa jhanas) as one of the ways the first person was freed, he didn’t specify the second way.
Meanwhile, the second person was freed “by means of intuitive wisdom”, without having apprehended the arupa jhanas, and the third person was not freed, in spite of having apprehended the arupa jhanas.
I was astonished to find that in MN 4, Gautama described a suppleness of mind in the fourth rupa (“corporeal”) jhana, with which he directed his mind to “the knowledge and recollection of former habitations”, then to “the knowledge of the passing hence and the arising of beings”, then to “the knowledge and destruction of the cankers” (all translations here Pali Text Society, this one MN vol. I p 28).
The two “persons” freed in Gautama’s description of the seven persons had both completely destroyed the cankers. The remaining five had not completely destroyed the cankers.
For years, I labored under the assumption that the apprehension of the arupa jhanas was necessary to enlightenment. Assuming the destruction of the cankers is synonymous with enlightenment, then not so, according to MN 4: only the fourth rupa jhana and the perception of prior habitations and prior lives is necessary to discerning the four truths and the destruction of the cankers.
Moreover, from the lecture on seven persons, the arupa jhanas are insufficient in and of themselves to guarantee complete destruction of the cankers. Intuitive wisdom is apparently required, derived through a freedom and the knowledge of that freedom, in order to realize the complete destruction of the cankers.
In Satipatthana (MN 10), it’s “profound knowledge here-now” that’s arrived at instead of “intuitive wisdom”, but I have to believe these are the same. Although Satipatthana mentions concentration only in passing as one of the seven links in awakening, Maha Satipatthana (DN 22) gives particulars of the four rupa jhanas, as well as particulars of the four truths that Gautama directed his mind to in MN 4.
Meanwhile, in MN 121, Gautama recounted his passage through the arupa jhanas to the signless concentration of mind (the final arupa jhana). He described the thought of impermanence that followed, and his subsequent arrival at freedom from the cankers and the knowledge of that freedom. I had thought, based on that description, that the arupa jhanas were necessary, to arrive at freedom and knowledge and the complete destruction of the cankers, hence my surprise at the account in MN 4.
Reflecting on all this now, I’m struck that the description of the seven persons is a reconciliation of these teachings, the one requiring only the fourth rupa jhana and the knowledge and recollection of “past habitations” and “the passing hence and arisings of beings” to arrive at the destruction of the cankers, and the one requiring the arupa jhanas (and in the description of the first “person”, now also “intuitive wisdom”, so “both ways”).
That would suggest that MN 4 and MN 10, as well as DN 22, preceded MN 70 and MN 121, historically.
Moreover, in SN 54.8, Gautama states that the mindfulness described in MN 118 (Anapanasati Sutta) was his way of living before enlightenment–and after enlightenment too, in 54.11. That would seem light-years away from MN 10 and DN 22.
I’m guessing there was a change of tack, after the suicide of so many monks described in SN 54.9 (and somewhere in Vinaya). Not many can discern prior habitations and the passing hence and arisings of beings, not many can abide in the arupa jhanas, either of these avenues to the destruction of the cankers requires special talent in my estimation. Since Gautama practiced his way of living prior to his enlightenment, special talent is not necessary to live with a mindfulness like that with which Gautama lived, and that’s the whole point of SN 54. 9.
There’s hope for the rest of us yet, but it took a lot of years and the lives of many monks for Gautama to arrive at teaching that, in my estimation.
