Vasudevaḥ sarvam iti sa mahātmā su-durlabhaḥ (BG 7.19). One who understands Kṛṣṇa perfectly . . . we cannot understand Kṛṣṇa perfectly, that is not possible. But as far as our knowledge is concerned, as far as we can study Vedas, if we simply can understand that Kṛṣṇa is the origin of everything, īśvaraḥ paramaḥ kṛṣṇaḥ . . . (Bs. 5.1) Paramaḥ kṛṣṇaḥ. Every one of us, somehow or other, we are īśvaraḥ. Īśvaraḥ means controller. So we have got some controlling capacity, according to our capacity, but we are not the supreme controller. That is not possible.
Supreme controller is Kṛṣṇa. You may be controller. I am controller, but above me there is another controller, above him there is another controller, above him there is another controller. In this way, within this material world, the supreme controller is Brahmā—within this material world, not beyond this material world. Only on the . . . on this universe, in each and every universe, there are many Brahmās, many Rudras, and many other demigods—many suns, many moons, many, many, millions.
- yasya prabhā prabhavato jagad-aṇḍa-koṭi-
- koṭiṣv (aśeṣa)-vasudhādi-vibhūti-bhinnam
- tad brahma niṣkalam anantam aśeṣa-bhūtaṁ
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.40)
So everything is Kṛṣṇa's energy; therefore Kṛṣṇa says, mayā tatam idaṁ sarvam (BG 9.4). Sarvaṁ khalv idaṁ brahma (Chāndogya Upaniṣad 3.14.1) means Kṛṣṇa's energy is spread everywhere, everything. Parasya brahmaṇaḥ śaktiḥ.
That expansion, in the Viṣṇu Purāṇa it is said:
- eka-sthāni (deśa)-sthitasyāgner
- jyotsnā vistāriṇī yathā
- parasya brahmaṇaḥ śaktis
- sarvaiva (tathedam) akhilaṁ jagat
- (Viṣṇu Purāṇa 1.22.52)
Sarvedam akhilaṁ jagat. Idaṁ sarvam. Whatever we are seeing, they are simply expansion of Kṛṣṇa's energy. Just like a big merchant, a big industrialist, he has got big, big factories. So these factories, he . . . one can say that this is Mr. Birla's factory or Mr. such-and-such gentleman's factory, Tata's factory. But still, although the factory belongs to Tata, the factory is running on by the energy of Tata, but you cannot find, if you want to see where is Tata here, Mr. Tata, that you cannot see. Tata is seeing . . . sitting in his room and is pulling button and everything is going on.
