Sanskrit:

गायन्त्य उच्चैरमुमेव संहताविचिक्युरुन्मत्तकवद् वनाद् वनम् ।पप्रच्छुराकाशवदन्तरं बहि-र्भूतेषु सन्तं पुरुषं वनस्पतीन् ॥ ४ ॥

ITRANS:

gāyantya uccair amum eva saṁhatāvicikyur unmattaka-vad vanād vanampapracchur ākāśa-vad antaraṁ bahirbhūteṣu santaṁ puruṣaṁ vanaspatīn

Translation:

Singing loudly of Kṛṣṇa, they searched for Him throughout the Vṛndāvana forest like a band of madwomen. They even asked the trees about Him, who as the Supersoul is present inside and outside of all created things, just like the sky.

Purport:

Lost in the madness of love for Kṛṣṇa, the gopīs inquired about Him from even the trees in Vṛndāvana. Of course, there is no actual separation from Lord Kṛṣṇa, since He is the all-pervading Supersoul.
