CC Madhya 8.111, Translation and Purport:
“"The progress of loving affairs between a young boy and a young girl is like the movement of a snake. On account of this, two types of anger arise between a young boy and girl—anger with cause and anger without cause."
During the rāsa dance, one form of Kṛṣṇa was between every two gopīs. But by the side of Śrīmatī Rādhārāṇī there was only one Kṛṣṇa. Although this was the case, Śrīmatī Rādhārāṇī still manifested disagreement with Kṛṣṇa. This verse is from the Ujjvala-nīlamaṇi (Śṛṅgāra-bheda-kathana 102), written by Śrīla Rūpa Gosvāmī.
