divya-unmāde - in transcendental madness; aiche - such; haya - is; ki ihā vismaya - what is the wonder; adhirūḍha-bhāve - in highly elevated love of Kṛṣṇa; divya-unmāda - in transcendental madness; pralāpa - talking; haya - there is.

Such is the state of transcendental madness. Why is it difficult to understand? When one is highly elevated in love of Kṛṣṇa, he becomes transcendentally mad and talks like a madman.
