Some comment.
- Prajnaparamita sutras, and also the Madhyamaka treatises that explain them, is a reaction/ critique to Abhidharma.
In my opinion, it is not that the Abhidharma is wrong, but their assertion that these “dharmas” have their own svabhava can result in wrong view. That there is a “self” or something that can be identified as a “self”
svabhava = own being, self nature, intrinsic nature, self existence, etc.
Prajnaparamita sutras will shock the readers by saying, all those dharmas/ phenomena are empty, not exist etc. This is to counter eternalist tendency that arise in people who study the Abhidharma.
We can read the early part of longer prajnaparamita sutras, they are full of terms and concept that only known by people who study Abhidharma. So the target audience is clear.
When we study Abhidharma, our mind can be trapped in classification, categories, concept, and we can grasp at theories, rather than practice them. The teaching become new object of attachment. Here, Heart Sutra try to tell us not to be attached even to the Teaching. The difference between Heart Sutra and the longer Prajnaparamita sutra, is that the latter give longer list. Someone explain it well why the list is becoming longer and longer…
The Heart Sutra and the other Prajnaparamita Sutras talk about a lot of things, but their most fundamental theme is the basic groundlessness of our experience. They say that no matter what we do, no matter what we say, and no matter what we feel, we need not believe any of it. There is nothing whatsoever to hold on to, and even that is not sure. So these sutras pull the rug out from under us all the time and take away all our favorite toys. Usually when someone takes away one of our mental toys we just find new toys. That is one of the reasons why many of the Prajnaparamita Sutras are so long—they list all the toys we can think of and even more, but our mind still keeps grasping at new ones. The basic point is to get to a place where we actually stop searching for and grasping at the next toy. Then we need to see how that state of mind feels. How does our mind feel when we are not grasping at anything, when we are not trying to entertain ourselves, and when our mind is not going outside (or not going anywhere at all), when there is no place left to go?

- You can trace the teaching back to Buddha himself. In longer Prajnaparamita sutra, (I check the 10.000 lines and 25.000 lines version), there is a saying at the beginning:
prajñāpāramitā prajñāpāramitety ucyate yad idaṃ sarvadharmānabhiniveśaḥ.
= that which is called the transcendent perfection of wisdom is the absence of fixation with respect to all things
translation by : The Transcendent Perfection of Wisdom in Ten Thousand Lines / 84000 Reading Room (paragraph 1.10)
This is just a rephrasing of a famous sentence:
“sabbe dhammā nālaṁ abhinivesāyā.”
Nothing is worth insisting on
MN 37 SuttaCentral
The term abhinivesa is one interesting term. Bhikkhu Sujato explained it once in
Minute 38:50
So even in early sutta, Buddha teach “do not grasp at any phenomena, all phenomena (sabbe dhamma) is not worth insisting”
Prajnaparamita sutra is only expanding the list of what is considered “all phenomena”.
- Another interesting phrase that is repeated again and again in long prajnaparamita sutra, is the 3 gateway to liberation. They are emptiness, signlessness, and wishlessness/undirectedness (sunyata, animitta, apanihita/ apranihita)
And they dont explain what these means, because everybody already know what that means, they are repeated often in the early sutta.
Especially in MN 121 there is nice explanation on how to go from emptiness immersion to signless immersion. SuttaCentral
This link to MN 121 is already mentioned in original essay above, so I think there is strong evidence that Prajnaparamita sutra is a rephrasing and expansion of existing older teaching, aimed at Abhidharma students.
