Śrīmad-Bhāgavatam · Text 10.80.3
Who is speaking and story frame
सा वाग् यया तस्य गुणान् गृणीते
करौ च तत्कर्मकरौ मनश्च ।
स्मरेद् वसन्तं स्थिरजङ्गमेषु
शृणोति तत्पुण्यकथा: स कर्ण: ॥ ३ ॥
sā vāg yayā tasya guṇān gṛṇīte
karau ca tat-karma-karau manaś ca
smared vasantaṁ sthira-jaṅgameṣu
śṛṇoti tat-puṇya-kathāḥ sa karṇaḥ
Actual speech is that which describes the qualities of the Lord, real hands are those that work for Him, a true mind is that which always remembers Him dwelling within everything moving and nonmoving, and actual ears are those that listen to sanctifying topics about Him.
