this is what i understand.
that stream entry is free from fermentation
it is not only Arahant who is free from fermentation
Sabbasava Sutta: Discourse on All Āsavashttp://www.accesstoinsight.org/tipitaka ... .bpit.html
anyway this translation is different
here is another linkviewtopic.php?f=25&t=1741
all the fermentation sutta
here it explains that stream entry has abandon effluents(fermentation) by seeing.(he is free from effluents)
"And what are the ideas fit for attention that he does attend to? Whatever ideas such that, when he attends to them, the unarisen fermentation of sensuality does not arise in him, and the arisen fermentation of sensuality is abandoned; the unarisen fermentation of becoming does not arise in him, and the arisen fermentation of becoming is abandoned; the unarisen fermentation of ignorance does not arise in him, and the arisen fermentation of ignorance is abandoned. These are the ideas fit for attention that he does attend to. Through his not attending to ideas unfit for attention and through his attending to ideas fit for attention, unarisen fermentations do not arise in him, and arisen fermentations are abandoned.
"He attends appropriately, This is stress... This is the origination of stress... This is the cessation of stress... This is the way leading to the cessation of stress. As he attends appropriately in this way, three fetters are abandoned in him: identity-view, doubt, and grasping at precepts & practices. These are called the fermentations to be abandoned by seeing.
again it is not only Arahant who is free from effluents.
this sutta supports the Great forty sutta.
it supports the supra mundane view/noble mind/analysis of factor/and fully posses of the path
And what is the right view that is without effluents, transcendent, a factor of the path? The discernment, the faculty of discernment, the strength of discernment, analysis of qualities as a factor for Awakening, the path factor of right view of one developing the noble path whose mind is noble, whose mind is free from effluents, who is fully possessed of the noble path. This is the right view that is without effluents, transcendent, a factor of the path.
