Gargamuni: Page one. "Similarly, in the Second Canto, the post-creation cosmic manifestation is described. The different planetary systems are described in the Second Canto as different parts of the universal body of the Lord. For this reason, the Second Canto can be called "The Cosmic Manifestation." There are ten chapters in the Second Canto, and in these ten chapters the purpose of Śrīmad-Bhāgavatam and the different symptoms of this purpose are narrated. In the first chapter the glories of chanting are described and the process of meditation on the universal form of the Lord by the neophyte devotees is hinted. In the first verse Śukadeva Gosvāmī replies to the questions of Mahārāja Parīkṣit, who asked him about one's duty at the point of his death. Mahārāja Parīkṣit was glad to receive Śukadeva Gosvāmī and he was proud of being a descendant of Arjuna, the intimate friend of Kṛṣṇa. Personally, he was very humble and meek, but he expressed his gladness that Lord Kṛṣṇa was very kind to the sons of Pāṇḍu, or his grandfathers, especially his own grandfather Arjuna. And because Lord Kṛṣṇa is always pleased with His family, therefore at the verge of Mahārāja Parīkṣit's death, Śukadeva Gosvāmī was sent to help him in the process of self-realization."
Prabhupāda: This is confirming the statement of Caitanya-caritāmṛta, that guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja (CC Madhya 19.151). Two things required, Guru and Kṛṣṇa, to advance in the spiritual realization or Kṛṣṇa consciousness. So here it is, Kṛṣṇa is pleased in the family of the Pāṇḍavas. So Parīkṣit Mahārāja was going to die. Parīkṣit Mahārāja was grandson of Arjuna, and he was also a devotee. So therefore by the mercy of Kṛṣṇa, a bona fide spiritual master is sent to Parīkṣit Mahārāja. Guru-Kṛṣṇa. When one is sincere, then Kṛṣṇa is sitting within everyone. As soon as He sees that "Here is a sincere soul. He's seeking after Me," so He manifests Himself out externally as spiritual master. The spiritual master is therefore representative of Kṛṣṇa. Guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja (CC Madhya 19.151). Two things. Without being representative of Kṛṣṇa, nobody can become spiritual master. Kṛṣṇa-śakti vinā nahe tāra pravartana. Without being empowered by Kṛṣṇa, nobody can preach, nobody can become a spiritual master.
