In the Vedas we understand the nature of the Absolute Truth as ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). He's ānandamaya, always in pleasure potency. So when Kṛṣṇa, the Absolute Personality of Godhead, wants to enjoy ānanda, so He expands His ahladini-śakti. Parāsya śaktir vividhaiva śrūyate (CC Madhya 13.65, purport). This is Vedic injunction. He has got multipotencies. So when He wants to enjoy, He expands His internal potency, ahlādinī-śakti. That is Śrīmati Rādhārāṇī. Don't think Śrīmati Rādhārāṇī a ordinary girl. No. Then you will mistake. How Kṛṣṇa, the Supreme Personality of Godhead, can dance with ordinary girl? No. That is not possible. Cid-vilāsī. He is enjoyer of the internal potency. That is described by Śrīla Svarūpa Dāmodara:
- rādhā-kṛṣṇa-praṇaya-vikṛtir ahlādinī śaktir asmād
- ekātmānāv api deha-bhedaṁ gatau tau
- śrī-caitanyākhyaṁ prakaṭam adhunā tad-dvayaṁ caikyam
- āptaṁ rādhā-bhava-dyuti . . .
- (CC Adi 1.5)
Caitanyākhyam, kṛṣṇākhyam, like that. So rādhā-kṛṣṇa-praṇaya, the loving affairs of Rādhā and Kṛṣṇa, that is the expansion of Kṛṣṇa's ahlādinī-śakti. Sandhinī-śakti and ahlādinī-śakti . . . there are many potencies of Kṛṣṇa.
So Kṛṣṇa is Para-brahman. Para-brahman. He is accepted as Para-brahman in the Bhagavad-gītā by Arjuna: paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12). He's Para-brahman, Supreme Brahman. The Māyāvādīs, they cannot understand the Supreme Brahman, or the Supreme ātmā, Paramātmā. These words are there, ātmā, paramātmā; brahma, paraṁ brahma; īśvara, parameśvara. These words are there. But they, on account of their poor fund of knowledge, they think ātmā and Paramātmā the same, or īśvara or Parameśvara is the same, or Brahman or Para-brahman is the same. That is poor fund of knowledge.
