Nārāyaṇa, or Kṛṣṇa, is not one of the products of this material creation; therefore it is to be understood that Kṛṣṇa's body is not material. But the Māyāvādī philosophers, they think like that, that Kṛṣṇa is God, but He has accepted a material body. This is Māyāvādī philosophy. But how Kṛṣṇa can accept a material body, because He existed before the material creation?
Another consideration is that even if we accept a material body, that is not material for Him. That is also spiritual. It appears to us as material, but that is spiritual. Parāsya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8, CC Madhya 13.65, purport). He has got multi-energies, and because He is spirit, complete spirit, therefore His energies are also spiritual. Śakti-śaktimator abhedaḥ. There cannot be any distinction between the powerful and the power.
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.
In the Bhagavad-gītā there is another instance. When Arjuna asked Kṛṣṇa, Kṛṣṇa said, imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). Kṛṣṇa said that, "First of all, I narrated this yoga system of Bhagavad-gītā to the sun god." So, in order to clear this matter, Arjuna inquired from Him, "My dear Kṛṣṇa, we are born very recently. How is that, You narrated this yoga system to the sun god?" Arjuna, of course, knew everything, but in order to clear our doubts, he raised this question. And Kṛṣṇa answered that "You were also present at that time, but you have forgotten. I have not forgotten."
So this is another proof that Kṛṣṇa . . . Kṛṣṇa's body does not change. Kṛṣṇa, when He comes, when He appears, He comes in His original, spiritual body. Therefore Kṛṣṇa has warned that avajānanti māṁ mūḍhāḥ (BG 9.11). The Māyāvādī philosophers who think that Kṛṣṇa has accepted a material body, they are described as mūḍha. They have no sufficient knowledge. Paraṁ bhāvam ajānantaḥ. They do not know what is the power behind Kṛṣṇa.
So Kṛṣṇa creates. Before creation, aham ādir hi devānām (BG 10.2). In the Bhagavad-gītā it is said, devānām. First of all, Brahmā was created. Then other great sages were created. Then other demigods were created. But Kṛṣṇa says, aham ādir hi devānām. Therefore He's not a created being of this material world. We have to consider in that way.
