Love Krishna first, and you will naturally love everything; love anything else, and you will remain eternally frustrated.Listen — Srila Prabhupada Uvaca
Śrī Brahma-saṁhitā 5.37 — August 11, 1971, London 710811BS-LONDON [16:05 Minutes] Brahma-samhita-05.37_710811BS-LONDON Prabhupāda: [aside:] I have to speak something? So we are worshiping Rādhā-Mādhava, the lover, or enjoyer, of Rādhārāṇī. [break] Govindam ādi-puruṣaṁ tam ahaṁ bhajāmi **. ānanda-cinmaya-rasa-pratibhāvitābhis tābhir ya eva nija-rūpatayā kalābhiḥ goloka eva nivasaty akhilātma-bhūto govindam ādi-puruṣaṁ tam ahaṁ bhajāmi [Bs. 5.37] Ānanda-cinmaya-rasa. Rādhā-Kṛṣṇa, Govinda, is enjoying ānanda-cinmaya-rasa, spiritual bliss. Cinmaya means spiritual, and rasa, bliss. That is eternal.
We are also particles of that ānanda-cinmaya-rasa. Ānandamayo 'bhyāsāt [Vedānta-sūtra 1.1.12]. The Vedānta-sūtra says every living entity is ānanda-maya. Nature, living entity's nature, is to be blissful, happy, always pleasing, but in our material condition of life we are just the opposite. There is neither pleasure, nor knowledge, nor eternity. But these three things are the symptoms of spiritual existence: eternity, blissfulness and knowledge, sat-cid-ānanda. So Kṛṣṇa is fully ānanda-cinmaya-rasa.
Kṛṣṇa's pleasure, Kṛṣṇa's enjoyment with Rādhārāṇī, that is not material. If we take it as material, then there is mistake. Ānanda-cinmaya-rasa-pratibhāvitābhi. Not only Kṛṣṇa, Rādhārāṇī, but in the Goloka Vṛndāvana, everything—the land, the water, the trees, the flowers, the cows, the cowherds boy—everything, they are expansion of Kṛṣṇa's internal potency, ānanda-cinmaya-rasa. Ānanda-cinmaya-rasa-pratibhāvitābhis tābhir ya eva nija-rūpatayā kalābhiḥ [Bs. 5.37]. That is Kṛṣṇa's expansion of His own person.
Just like when Brahmā stolen all the cows and calves and cowherd boys of Kṛṣṇa to test Kṛṣṇa, whether He is actually the Supreme Personality of Godhead, Kṛṣṇa immediately expanded Himself in the typical same way: all the cows, calves, cowherd boys. So there, in the spiritual world, Kṛṣṇa's energy, everything there—variety, all variety. Here also, the varieties are there. That is expansion of Kṛṣṇa's material energy, and in the spiritual world the varieties are expansion of Kṛṣṇa's spiritual energy. Ānanda-cinmaya-rasa-pratibhāvitābhis tābhir ya eva nija-rūpatayā kalā... Nija-rūpa, His own form, expansion.
Goloka eva nivasati: Goloka Vṛndāvana. He is permanent resident there. Akhilātma-bhūto, but He is everywhere. He is, although situated in His own abode, Goloka Vṛndāvana, He's..., He can expand Himself.
Because this material energy is also His energy, so from His energy He can manifest Himself anywhere. So here the Lord Kṛṣṇa and Rādhārāṇī, that is the same Kṛṣṇa and Rādhārāṇī who are in the Goloka Vṛndāvana. It is simply expansion to give us facility to accept our service. I think I have given many times this example: Just like in front of your door there is a mailbox. That mailbox, although it appears to be small box, but it is Post Office.
It is not different from Post Office. The practical example is that you place your letters within the box and it goes thousands and thousand miles away. Therefore it is Post Office. Don't think that it is different from the Post Office. Similarly, ānanda-cinmaya-rasa expansion—this Deity.
