Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 27
Sanskrit:
तथापि सूनृता सौम्य हृदि न स्थीयते चले ।पुत्रानुरागविषमे विद्युत् सौदामनी यथा ॥ २७ ॥
ITRANS:
tathāpi sūnṛtā saumyahṛdi na sthīyate caleputrānurāga-viṣamevidyut saudāmanī yathā
Translation:
Even so, gentle Akrūra, because my unsteady heart is prejudiced by affection for my sons, these pleasing words of yours cannot remain fixed there, just as lightning cannot remain fixed in a cloud.
