Vrindavana is Krishna's transcendental domain where all beings eternally serve through their natural propensity.Listen — Srila Prabhupada Uvaca
Śrī Caitanya-caritāmṛta, Ādi-līlā 1.16 — April 9, 1975, Māyāpur 750409CC-MAYAPUR [30:23 Minutes] CcAdi-01.016_750409CC-MAYAPUR Santoṣa: Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [Prabhupāda and devotees repeat] [leads chanting of verse, etc.] dīvyad-vṛndāraṇya-kalpa-drumādhahśrīmad-ratnāgāra-siṁhāsana-sthau śrīmad-rādhā-śrīla-govinda-devau preṣṭālībhiḥ sevyamānau smarāmi [Cc. Ādi 1.16] [00:52] "In a temple of jewels in Vṛndāvana, underneath a desire tree, Śrī Śrī Rādhā-Govinda, served by Their most confidential associates, sit upon an effulgent throne.
I offer my humble obeisances unto Them." Prabhupāda: dīvyad-vṛndāraṇya-kalpa-drumādhahśrīmad-ratnāgāra-siṁhāsana-sthau śrīmad-rādhā-śrīla-govinda-devau preṣṭālībhiḥ sevyamānau smarāmi [Cc. Ādi 1.16] So, description of Vṛndāvana, Vṛndāvana, and Rādhā and Kṛṣṇa situated there. The Vṛndāvana... Vana means forest, and vṛnda means tulasī. Mostly there are tulasī plants and other trees also, but all the trees are living desire trees, spiritual.
They can serve Kṛṣṇa in any way, desire. They have become trees by their voluntary desire. They're all spiritual beings—there is no force—but everyone has got a particular tendency to serve Kṛṣṇa in a different way. So these trees and plants, they are also living beings.
They are not ordinary living beings, but they have decided to serve Kṛṣṇa by supplying fruits and flowers. They want that service. Everyone has got his particular propensity. So someone is serving as the land there; someone is serving as the throne; someone is serving as the supplying agent of fruits and flowers; someone is engaged in His service as the gopīs, confidential servitors.
The cows, calves, everything—they are all different living entities. They are not made of these material things, material body. Ānanda-cinmaya-rasa-pratibhāvitābhis tābhir ya eva nija-rūpatayā kalābhiḥ [Bs. 5.37]. They are all also expansion of Kṛṣṇa's pleasure potency. In one sense they are also Kṛṣṇa; they are not different from Kṛṣṇa. Śakti-śaktimatayor abheda: "The power and the powerful, they are not different—identical." Just like the sun and the sunshine.
So in the sun globe there is heat and light, and the sunshine there is heat and light. So, so far heat and light is concerned, they are one. Similarly, Kṛṣṇa and Kṛṣṇa's pleasure potency, ānanda-cinmaya, ahlādinī... It is already described, rādhā kṛṣṇa-praṇaya-vikṛtir hlādinī-śaktir asmāt [Cc. Ādi 1.5]. So whatever description is there of Vṛndāvana, that is expansion of Kṛṣṇa's pleasure potency.
They are not different. Therefore in the beginning it is said dīvyad, "shining," or "divine," "transcendental." So we should not consider Vṛndāvana as ordinary forest. Here we have got Vṛndāvana on this planet. That is also not ordinary forest.
