Kṛṣṇa has got two energies. Just like heat and light, the energies of the fire. Similarly, Kṛṣṇa is enjoying His spiritual, blissful life. He is spiritual, sac-cid-ānanda-vigrahaḥ ānanda... (Bs. 5.1). Ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). So He is in Vṛndāvana having His ānanda, spiritual bliss, enjoyment, with His associates, ever associ..., eternal associates, the gopīs, the cowherds boys, His mother, His father, Mother Yaśodā, Nanda, Nanda Mahārāja. So He is enjoying in His abode, Goloka. That is also confirmed: goloka eva nivasaty akhilātma-bhūtaḥ (Bs. 5.37). Still, He is present everywhere. Ekāṁśena sthito jagat (BG 10.42). Aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35). He is within this universe, He is within your heart... Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). In one word: without Him, nothing can exist. Therefore it is said, mayi sarvam idaṁ protam: "Everything is existing in Me." Sarvam idam.
The two energies... In the material world, the two energies are working. The two energies are from Kṛṣṇa. Therefore everything is resting on Kṛṣṇa. In another place Kṛṣṇa says, mayā tatam idaṁ sarvam (BG 9.4). The same thing: "I am expanded." Tatam. Tatam means expanded. So He is expanded by His energy. Just like the lamp is expanded by the light. When the illumination in the lamp will be stopped, the expansion also will stop. Similarly, whatever we see, it is all resting on Kṛṣṇa's energy. It is working on Kṛṣṇa's energy. Just like I am... It is not very difficult to understand. Just like I am. What is "I am"? Am I this body? No, I am not this body. The body is my house. I am living in the house. Am I this mind? No, I am not this mind. This is called meditation, to understand, "I am not this body, I am not this..." Neti neti. "I am, ahaṁ brahmāsmi."
