Arv 12 cmy – frankk
1) 31asb instead of s&s. Also, 35 body parts instead of 31, same simile of bag full of grains as in Theravada
2) pleasant abiding -
AN 4.41 mentions all 4 jhanas = pleasant abiding,
only says first 3 jhanas = pleasant abiding.
Arv 12 uses first 3 jhana similes from AN 5.28
. The full anatomical body pervasion
a) from seclusion is a reference to first jhana,
b) from samadhi is a reference to second jhana
c) the pond with 3 types of lotus is reference to third jhana
Arv 12 agrees with AN 6.29
3) same as theravada, but we get a simile for aloka sanna:
Just as though, monastics, in the first month of the summer the days are cloudless, without thunder or rain, or mists, and in the middle of the day, as far as there is light, it is pure, fulfilled, luminous, and there is no darkness found, so, monastics, a monastic grasps well and truly the perception of light, applies his mind well, sees it well, penetrates it well, by day he cultivates his illumined mind, determined on the perception, as by day, so by night, as by night, so by day; as before, so later, as later, so before; as below, so above, as above, so below.
4) AN 4.41 talks about penetrating 5uk aggregates to realize arahantship by destruction of asavas.
Arv 12, expresses the same idea differently, with an explicit declaration of 4th jhana, and that is used to acquire panna:
Iyaṁ samādhi-bhāvanā āsevitā bhāvitā bahulīkṛtā prajñā-pratilambhāya saṁvartate ||
This is the cultivation of meditation which, when practised, developed, made much of, leads to the acquisition of wisdom.
AN 6.29 expresses the same idea with 4th jhana's purpose being aneka dhatu pati vedaya (penetration of many elements)
