ei-mata - in this way; tāṇḍava-nṛtya - devastating dancing; kaila - performed; kata-kṣaṇa - for some time; bhāva-viśeṣe - in a particular ecstasy; prabhura - of Lord Caitanya Mahāprabhu; praveśila mana - the mind entered.

After Śrī Caitanya Mahāprabhu had performed His devastating dance for some time, His mind entered into a mood of ecstatic love.
