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.
So you cannot become a mahā-bhāgavata all of a sudden, but from kaniṣṭha-adhikārī,
- arcāyām eva haraye
- yaḥ pūjāṁ śraddhayehate
- na tad-bhakteṣu cānyeṣu
- sa bhaktaḥ prākṛtaḥ smṛtaḥ
- (SB 11.2.47)
Prākṛtaḥ stage. So prakṛtaḥ stage means just like we are worshiping the Deity, but not only we shall worship Deity, but we make advancement. What is that advancement? To become gradually a preacher. That is madhyama-adhikārī, second stage: preacher. Preacher means that,
- īśvare tad-adhīneṣu
- bāliśeṣu dviṣatsu ca
- prema-maitrī-kṛpā upekṣāḥ
- yaḥ karoti sa madhyamaḥ
- (SB 11.2.46)
When you become fully Kṛṣṇa conscious by worshiping the Deity regularly, as we have got prescription to rise early in the morning, offer maṅgala-ārati, then kīrtana, then class, in this way practicing, practicing, when you become advanced Kṛṣṇa conscious, then your natural tendency will be how to preach.
