So Prahlāda Mahārāja, he is nitya-siddha. Nitya-siddha means there are living entities, every living entity is part and parcel of Kṛṣṇa. So one who does not fall down, he is called nitya-siddha. One who does not fall down. Just like in this material world there are millions and millions of living entities, but they have fallen down. But there are multi-millions and millions of living entities in the vaikuṇṭha-loka, they never fall down. They are called nitya-siddha. They never come here. So we have no information. This is only one-fourth manifestation of God's creation, and the three-fourths creation of God is there. Not creation; it is everlasting. Just like in the prison house, if you go to the prison house, it does not mean that the whole state is there. It is only insignificant part of the state, and only the criminals they are put together.
So this material world . . . Material world means so many planets you see—so many stars and planets: the sun planet, moon planet and loka, sarva-loka-maheśvaram (BG 5.29). This is one universe, and there are millions of universes. Altogether that is material world, and that is one part of creation. Ekāṁśena sthito jagat (BG 10.42). The jagat means this material world. So the whole material, ananta koṭi. Yasya prabhā prabhavato jagad-aṇḍa-koṭi-koṭiṣv aśeṣa vasudhādi vibhūti-bhinnam (BS 5.40). This ananta-koṭi-brahmāṇḍa is only one-fourth manifestation of God's creation, and just imagine what is the other three-fourth. That is spiritual world.
So the nitya-siddha mahā-bhāgavata, they come from the spiritual world on the order of the Supreme Personality of Godhead, and they, by example, they preach Kṛṣṇa consciousness. This is mahā-bhāgavata. By suffering, by example, everything, they look like ordinary men, but mahā-bhāgavata. How it is tested? Never forgets Kṛṣṇa. This is mahā-bhāgavata nitya-siddha. And sādhana-siddha means those who are put into this material world, by the association of mahā-bhāgavata, if he tries, follows, then he can also become mahā-bhāgavata or nitya-siddha, because originally everyone is nitya-siddha.
- nitya-siddha kṛṣṇa-bhakti 'sādhya' kabhu naya
- śravaṇādi-śuddha-citte karaye udaya
- (CC Madhya 22.107)
Every living entity originally nitya-siddha, but somehow or other, just like Jaya-Vijaya fell down in this material world, and he was delivered also, both of them were delivered. So although you have fallen in this material world and suffering the pangs of material existence, janma-mṛtyu-jarā-vyādhi (BG 13.9), on account of accepting this material body, still, Kṛṣṇa personally comes, yadā yadā hi dharmasya glānir bhavati bhārata (BG 4.7). This is glāniḥ, discrepancies. We are living this material existence. This is not real life. Real life is to become mahā-bhāgavata.
