prema-parakāśa nahe kṛṣṇa-śakti vine
'kṛṣṇa'--eka prema-dātā, śāstra-pramāṇe
prema—of ecstatic love of Kṛṣṇa; parakāśa—manifestation; nahe—cannot be; kṛṣṇa-śakti vine—without the power of Kṛṣṇa; kṛṣṇa—Lord Kṛṣṇa; eka—the only one; prema-dātā—giver of prema; śāstra-pramāṇe—the verdict of all revealed scriptures.
"Without being especially empowered by Kṛṣṇa, one cannot manifest ecstatic love of Kṛṣṇa, for Kṛṣṇa is the only one who gives ecstatic love. That is the verdict of all revealed scriptures.
