SB Introduction:

The author of Śrīmad-Bhāgavatam, Śrīla Vyāsadeva, first offers his respectful obeisances unto the paraṁ satyam (Absolute Truth), and because the paraṁ satyam is the ultimate source of all energies, the paraṁ satyam is the Supreme Person. The gods or the controllers are undoubtedly persons, but the paraṁ satyam from whom the gods derive powers of control is the Supreme Person. The Sanskrit word īśvara (controller) conveys the import of God, but the Supreme Person is called the parameśvara, or the supreme īśvara. The Supreme Person, or parameśvara, is the supreme conscious personality, and because He does not derive any power from any other source, He is supremely independent. In the Vedic literatures Brahmā is described as the supreme god or the head of all other gods like Indra, Candra and Varuṇa, but the Śrīmad-Bhāgavatam confirms that even Brahmā is not independent as far as his power and knowledge are concerned. He received knowledge in the form of the Vedas from the Supreme Person who resides within the heart of every living being. That Supreme Personality knows everything directly and indirectly. Individual infinitesimal persons, who are parts and parcels of the Supreme Personality, may know directly and indirectly everything about their bodies or external features, but the Supreme Personality knows everything about both His external and internal features.
