Yes, I am asking what the attha is.
Yes, commentary says it is the fruit of stream-entry.
However, there are many suttas that claim the benifit with another term but this one is unique.
I found no sutta sharing same term to express the fruit of stream entry.
But, there are a number of suttas that suggest different meditations are very fruitful and beneficial.
Ekadhammo, bhikkhave, bhāvito bahulīkato mahapphalo hoti mahānisaṃso. Katamo ekadhammo? Ānāpānassati
Mendicants, when one thing is developed and cultivated it’s very fruitful and beneficial. What one thing? Mindfulness of breathing (SN 54.1).
Mendicants, when mindfulness of death is developed and cultivated it’s very fruitful and beneficial. It culminates in the deathless and ends with the deathless (AN 6.19)
Aṭṭhikasaññā, bhikkhave, bhāvitā bahulīkatā mahapphalā hoti mahānisaṃsā.
Mendicants, when the perception of a skeleton is developed and cultivated it’s very fruitful and beneficial (SN 46.57).
Here also we endup with two terms.
mahapphalā - very fruitful
mahānisaṃsā - beneficial
What are the fruits? The four fruits?
What are the benifits?
And then SN 18.104.22.168 says,
Aṭṭhikasaññāya, bhikkhave, bhāvitāya bahulīkatāya dvinnaṃ phalānaṃ aññataraṃ phalaṃ pāṭikaṅkhaṃ—diṭṭheva dhamme aññā, sati vā upādisese anāgāmitā.
When the perception of a skeleton is developed and cultivated you can expect one of two results: enlightenment in the present life, or if there’s something left over, non-return.
With this sutta we can assume that very fruitful means attaining the perfection (arahant) or non-return.
Are there any other suttas to clarify the attha of the term?
mahatā atthena saṃyutto or mahapphalā hoti mahānisaṃsā
Are these terms share same meaning (attha)?
Is saṃyutta share a similar meaning with samannāgata in kandarakasutta ?
