In this age, Kali-yuga, this is the yugāvatāra, Lord Caitanya. And His description is mentioned in Śrīmad-Bhāgavatam. Five thousand years before, it was mentioned that kṛṣṇa-varṇam. Kṛṣṇa-varṇam means that He is in the category of Kṛṣṇa. Svayaṁ-kṛṣṇa. You can take the meaning of kṛṣṇa-varṇam like this. Varṇa means a caste or classification. So He is in the classification of the Supreme Lord, Kṛṣṇa. Or if you don't take that meaning, then kṛṣṇa-varṇam means He is always chanting "Kṛṣṇa." Kṛṣṇaṁ varṇayati. Varṇayati means chanting. So kṛṣṇa-varṇam, always engaged in Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. So this is the first feature. The symptoms of the yugāvatāra of this age is given like this, kṛṣṇa-varṇam. Either you can say that He is varṇayati... Varṇayati means describing only Kṛṣṇa. Lord Caitanya preached... His preaching mission was ārādhyo bhagavān vrajeśa-tanaya, Kṛṣṇa. Kṛṣṇa is the only worshipable object. And He was always chanting Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare. This is the first symptom of Lord Caitanya.
