Who is speaking and story frame
स गोदोहनमात्रं हि गृहेषु गृहमेधिनाम् ।
अवेक्षते महाभागस्तीर्थीकुर्वंस्तदाश्रमम् ॥ ८ ॥
sa go-dohana-mātraṁ hi
gṛheṣu gṛha-medhinām
avekṣate mahā-bhāgas
tīrthī-kurvaṁs tad āśramam
He [Śukadeva Gosvāmī] was accustomed to stay at the door of a householder only long enough for a cow to be milked. And he did this just to sanctify the residence.
