 (2) listening to the true Dharma is a limb for streamwinning; 

 (3) wise attention is a limb for streamwinning; 

 (4) practice of the Dharma in accordance with the Dharma is a limb for streamwinning.” .........

"Sāriputta, 'the stream, the stream,' so it is said. What now, Sāriputta, is the stream?” “The stream, bhante, is this noble eightfold path itself, namely, right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness, right concentration.”
