CC Adi-lila

When the rāsa dance was going on in full swing, Kṛṣṇa left all the gopīs and took only Śrīmatī Rādhārāṇī with Him.

CC Adi 6.71, Translation and Purport:

"O My Lord, O My husband, O most dearly beloved! O mighty-armed Lord! Where are You? Where are You? O My friend, reveal Yourself to Your maidservant, who is very much aggrieved by Your absence."

This verse is quoted from Śrīmad-Bhāgavatam (10.30.39). When the rāsa dance was going on in full swing, Kṛṣṇa left all the gopīs and took only Śrīmatī Rādhārāṇī with Him. At that time all the gopīs lamented, and Śrīmatī Rādhārāṇī, being proud of Her position, requested Kṛṣṇa to carry Her wherever He liked. Then Kṛṣṇa immediately disappeared from the scene, and Śrīmatī Rādhārāṇī began to lament.
