Cc. Madhya 6.13

'adhirūḍha bhāva' yāṅra, tāṅra e vikāra
manuṣyera dehe dekhi,—baḍa camatkāra

adhirūḍha bhāva—an ecstasy technically known as adhirūḍha; yāṅra—of whom; tāṅra—of Him; e—this; vikāra—transformation; manuṣyera—of a human being; dehe—in the body; dekhi—I see; baḍa camatkāra—very wonderful.

Sārvabhauma Bhaṭṭācārya considered, “The uncommon ecstatic symptoms of adhirūḍha-bhāva are appearing in the body of Śrī Caitanya Mahāprabhu. This is very wonderful! How are they possible in the body of a human being?”

Adhirūḍha-bhāva, or adhirūḍha-mahābhāva, is explained in the Ujjvala-nīlamaṇi, by Śrīla Rūpa Gosvāmī. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura quotes Rūpa Gosvāmī as follows: “The loving propensity of the āśraya (devotee) toward the viṣaya (Lord) becomes so ecstatic that even after enjoying the company of the beloved the devotee feels that his enjoyment is insufficient. At such a time, the lover sees the beloved in different ways. Such a development of ecstasy is called anurāga. When anurāga reaches its highest limit and becomes perceivable in the body, it is called bhāva. When the bodily symptoms are not very distinct, however, the emotional state is still called anurāga, not bhāva. When bhāva ecstasy is intensified, it is called mahā-bhāva. The symptoms of mahā-bhāva are visible only in the bodies of eternal associates like the gopīs.”
