So here it is clearly said that sa evedaṁ sasarjāgre bhagavān ātma-māyayā: "Bhagavān created by His energy." It is not that Bhagavān is finished after this creation. The Māyāvāda philosophy is that everything is God; therefore there is no separate existence of God. That is impersonalism. But here it is said that bhagavān ātma-māyayā: He created this cosmic manifestation by His energy. Pūrṇasya pūrṇam ādāya pūrṇam eva avaśiṣyate [Īśo Invocation]. His full energy, even it is taken away from Him, still, He is full, He's complete. He's not exhausted. So sa evedaṁ sasarjāgre bhagavān ātma-māyayā, sad-asad-rūpayā. The māyā is displayed... Māyā means energy. That is displayed in two ways: material and spiritual. Material is asat, and spiritual is sat. Asat means which does not exist permanent, permanently. Bhūtvā bhūtvā pralīyate [Bg. 8.19]. It is created, again it is annihilated. Therefore it is called sometimes asat. Asat means not false, but not permanent. So this material creation is also manifestation of Kṛṣṇa's energy, and there is another creation, but that is not creation. That is always existing.
That is the spiritual world, sanātana. Paras tasmāt tu bhāvaḥ anyaḥ avyaktaḥ avyaktāt sanātanaḥ [Bg. 8.20]. That, that manifestation, that is internal potency. This is external potency. This material world is manifestation of the external potency of Kṛṣṇa, whereas the spiritual world is the manifestation of His internal potency. Unfortunately, the modern advancement of education has no information what is that spiritual world. He has... They have no information. They are concerned with this material world only. That is also not perfectly. But there is spiritual world. Yad gatvā na nivartante tad dhāma paramaṁ mama [Bg. 15.6], Kṛṣṇa says. There is another, another manifestation of His internal potency. That is eternal, blissful and full of knowledge. Here, in this material world, material world means it is not eternal, not blissful and not full of knowledge. This is material world. In the Viṣṇu Purāṇa it is said: avidyā-karma-saṁjñānyā tṛtīyā śaktir iṣyate. This manifestation of energy is full of ignorance. The nature of this world is called darkness, tamasi, tama. Tamasi mā jyotir gama. So sad-asad-rūpayā cāsau guṇa, guṇamaya aguṇaḥ. Kṛṣṇa, when He's called aguṇa, or nirguṇa, that means He's not affected by these material modes of nature. Above material nature. We are affected. We living entities, we are affected by the material modes of nature, sattva-guṇa, rajo-guṇa, tamo-guṇa. But Kṛṣṇa is not affected. That is Kṛṣṇa..., difference between Kṛṣṇa and ourself.
