CC Antya 14.15

divyonmāde aiche haya, ki ihā vismaya?
adhirūḍha-bhāve divyonmāda-pralāpa haya
Word for word: 
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.
Translation: 
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.
