Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 13

Sanskrit:

पृच्छतेमा लता बाहूनप्याश्लिष्टा वनस्पते: ।नूनं तत्करजस्पृष्टा बिभ्रत्युत्पुलकान्यहो ॥ १३ ॥

ITRANS:

pṛcchatemā latā bāhūnapy āśliṣṭā vanaspateḥnūnaṁ tat-karaja-spṛṣṭābibhraty utpulakāny aho

Translation:

Let us ask these creepers about Kṛṣṇa. Even though they are embracing the arms of their husband, this tree, they certainly must have been touched by Kṛṣṇa’s fingernails, since out of joy they are manifesting eruptions on their skin.

Purport:

The gopīs reasoned that the creepers would not show signs of rapture merely by physical contact with their husband, a tree. Thus the gopīs concluded that although the creepers were embracing the strong limbs of their husband, they must have been touched by Lord Kṛṣṇa as He moved through the forest.
