Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura explains that the purport of the word abhimāna, or “self-conception,” is that Śrī Caitanya Mahāprabhu thought Himself to be in the position of Śrīmatī Rādhārāṇī and was always ready to render Kṛṣṇa service in that way. Although Śrī Caitanya Mahāprabhu is Kṛṣṇa Himself, He assumed the complexion and emotions of Śrīmatī Rādhārāṇī and remained in that status. He never assumed the complexion or status of Lord Kṛṣṇa. Of course, Kṛṣṇa wanted to experience the role of Śrīmatī Rādhārāṇī; that is the original cause of His assuming the body of Śrī Caitanya Mahāprabhu. Therefore pure Vaiṣṇavas never disturb Śrī Caitanya Mahāprabhu’s conception of being Śrīmatī Rādhārāṇī.
Unfortunately, at the present time a group of so-called devotees maintain that Śrī Caitanya Mahāprabhu is the enjoyer and that they are enjoyers as well. They have actually deviated from devotional service to the Lord. Śrī Caitanya Mahāprabhu manifested Himself to show that cultivation of love for Kṛṣṇa in separation is the easiest way of success for all living entities. Despite this fact, there are some theosophists who declare that because Śrī Caitanya Mahāprabhu is the Supreme Personality of Godhead, such cultivation is easy for Him but difficult for the living entity and that one can therefore approach Kṛṣṇa in any way he likes. To nullify this idea, Śrī Caitanya Mahāprabhu demonstrated practically how one can achieve love of Kṛṣṇa by adopting Śrīmatī Rādhārāṇī’s mood in separation from Kṛṣṇa.
