SB 10.30.4
gayantya uccair amum eva samhata
vicikyur unmattaka-vad vanad vanam
papracchur akasa-vad antaram bahir
bhutesu santam purusam vanaspatin
Translation:
Singing loudly of Krsna, they searched for Him throughout the Vrndavana 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 Krsna, the gopis inquired about Him from even the trees in Vrndavana. Of course, there is no actual separation from Lord Krsna, since He is the all-pervading Supersoul.
