Vṛndāvana means Rādhā-Kṛṣṇa's activities, pastimes. So that is the destiny of life. That is the real goal. As Śrī Caitanya..., Narottama dāsa Ṭhākura says, that manuṣya janama pāiyā, rādhā-kṛṣṇa nā bhajiyā, jāniyā śuniyā viṣa khāinu. One who has got this human form of life, if he does not understand what is Rādhā-Kṛṣṇa, his life is spoiled. Jāniyā śuniyā viṣa khāinu: knowingly they're eating poison, because by coming in contact with Rādhā and Kṛṣṇa they can go back to home, back to Godhead, and there will be no more janma-mṛtyu-jarā-vyādhi (BG 13.9). Such opportunity is human life, simply to understand Rādhā Kṛṣṇa. And therefore Śrī Caitanya Mahāprabhu is mahā-vadānyāvatāra, because He is teaching about the love of Rādhā-Kṛṣṇa and teaching everyone kṛṣṇa-prema-pradāyate, real destination of life, how to achieve kṛṣṇa-prema, and He's personally teaching. Namo mahā-vadānyāya. Rūpa Gosvāmī understood it: "Here is namo mahā-vadānyāya, most magnanimous incarnation."
Similarly, Locana dāsa Ṭhākura has sung,
- parama karuṇa, pahū dui-jana,
- nitāi-gauracandra
- saba avatāra, sāra śiromaṇi,
- kevala ānanda-kanda
Kevala ānanda-kanda, parama-karuṇa: "There are many incarnation, but no better incarnation, no magnanimous incarnation, like Śrī Caitanya Mahāprabhu, Nityānanda Prabhu." Nityānanda Prabhu is always... Vrajenda-nandana yei, śaci-suta haila sei, balarāma haila nitāi. Nitāi-Gaura means—Śrī Caitanya Mahāprabhu, who was formerly Kṛṣṇa... He's Kṛṣṇa still. Just for our understanding... As we think that "I had my former life"—actually I had—but that former life is finished; I am now a new life. But in case of the Supreme Personality of Godhead, it is not like that. It is simultaneously existing. Kṛṣṇa is also existing, and Śrī Caitanya Mahāprabhu also existing. The example is given in this connection, just like the sun. Now it is not visible in India, the sun. But other part, in America, it is visible. So sun is there, but it is not visible at the present moment in India. Similarly, Kṛṣṇa is there, Caitanya Mahāprabhu is there. Their pastimes are there, it is going on, but it is now not visible in this part of the universe. There are innumerable universes, so by rotation Kṛṣṇa or Caitanya Mahāprabhu comes to a particular universe at a certain period. Just like the sun will rise again, tomorrow morning, at six p.m., at six a.m., similarly, Caitanya Mahāprabhu and Kṛṣṇa and all His incarnation, they are rotating regularly.
