To taste the mellows of Śrīmatī Rādhārāṇī’s loving affairs in Her relationship with Kṛṣṇa, and to understand the reservoir of pleasure in Kṛṣṇa, Kṛṣṇa Himself, as Śrī Caitanya Mahāprabhu, accepted the mood of Rādhārāṇī.
In this connection Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura writes in his Anubhāṣya, “Śrī Gaurasundara is Kṛṣṇa Himself with the attitude of Śrīmatī Rādhārāṇī. Śrī Caitanya Mahāprabhu never gave up the attitude of the gopīs. He remained everlastingly predominated by Kṛṣṇa and never accepted the part of the predominator by imitating conjugal love with an ordinary woman, as sahajiyās generally do. He never placed Himself in the position of a debauchee. Lusty materialists like the members of the sahajiyā-sampradāya hanker after women, even others’ wives. But when they try to ascribe the responsibility for their lusty activities to Śrī Caitanya Mahāprabhu, they become offenders to Svarūpa Dāmodara and Śrīla Vṛndāvana dāsa Ṭhākura. In Śrī Caitanya-bhāgavata, Ādi-khaṇḍa, Chapter Fifteen, it is said:
sabe para-strīra prati nāhi parihāsa
strī dekhi’ dūre prabhu hayena eka-pāśa
‘Śrī Caitanya Mahāprabhu never even joked with others’ wives. As soon as He saw a woman coming, He would immediately give her ample room to pass without talking.’ He was extremely strict regarding the association of women. The sahajiyās, however, pose as followers of Śrī Caitanya Mahāprabhu although they indulge in lusty affairs with women. In His youth Lord Caitanya was very humorous with everyone, but He never joked with any woman, nor in this incarnation did He talk about women. The gaurāṅga-nāgarī party is not approved by Śrī Caitanya Mahāprabhu or Vṛndāvana dāsa Ṭhākura. Even though one may offer all kinds of prayers to Caitanya Mahāprabhu, one should strictly avoid worshiping Him as the Gaurāṅga Nāgara. The personal behavior of Śrī Caitanya Mahāprabhu and the verses written by Śrī Vṛndāvana dāsa Ṭhākura have completely repudiated the lusty desires of the gaurāṅga-nāgarīs.”
