Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 36
Sanskrit:
यावदालक्ष्यते केतुर्यावद् रेणू रथस्य च ।अनुप्रस्थापितात्मानो लेख्यानीवोपलक्षिता: ॥ ३६ ॥
ITRANS:
yāvad ālakṣyate keturyāvad reṇū rathasya caanuprasthāpitātmānolekhyānīvopalakṣitāḥ
Translation:
Sending their minds after Kṛṣṇa, the gopīs stood as motionless as figures in a painting. They remained there as long as the flag atop the chariot was visible, and even until they could no longer see the dust raised by the chariot wheels.
