Hi there, I have questions about Yuganaddha Sutta (AN 4.170):
In the sutta, we find 4 ways to attain arahantship, 3 of which are developing insight and tranquillity together whether one is preceeded by another or in tandem, but the fourth way is “controlling restlessness concerning the Dhamma (Dhammuddhacca)” where the commentary said it is the eradication of “the corruptions of insight”. Obviously, this commentary gloss are late because it has influence by the notion of dry-insight (insight-only way) which are not found in early suttas.
So the questions is: What is meant by “restlessness concerning the Dhamma (Dhammuddhacca)”? And how this fourth way of attaining arahantship to be done? Is it refer to a Dhamma-follower (Dhammanusari) type of stream-entry or something else?
And are this sutta or at least the fourth way of attaining arahantship are late addition? Considering it is spoken by a disciple (i.e., Venerable Ananda), it may be suspected to be not an authentic EBT. Although I see it has a paralel in the Samyukta Agama (SA 560), but I can not sure about the content of the parallel sutra because I can’t read Chinese.
