The following is an excerpt from a lecture given by Srila Prabhupada in London in 1969:
So our today prayer to Rādhārāṇī…We pray to Rādhārāṇī because She is the pleasure potency of Kṛṣṇa. Kṛṣṇa means “all-attractive.” But Rādhārāṇī is so great that She attracts Kṛṣṇa. Kṛṣṇa is all-attractive, and She is attracts Kṛṣṇa. So what is the position of Śrīmatī Rādhārāṇī? We should try to understand this today and offer our obeisances to Rādhārāṇī – Rādhe vṛndāvaneśvarī.
