This *oṁkāra* is known as *mahā-vākya,* or the supreme sound. Whatever meaning is in the supreme sound *oṁkāra* is further understood in the Gāyatrī *mantra.* Again, this same meaning is explained in *Śrīmad-Bhāgavatam* in the four *ślokas* known as *catuḥ-ślokī,* which begin with the words *ahaṁ evāsam evāgre.* The Lord says, "Only I existed before the creation." From this verse, four *ślokas* have been composed, and these are known as the *catuḥ-ślokī.* In this way the Supreme Personality of Godhead informed Lord Brahmā about the purpose of the *catuḥ-ślokī.* Again, Lord Brahmā explained this to Nārada Muni, and Nārada Muni explained it to Śrīla Vyāsadeva. This is the *paramparā* system, the disciplic succession. The import of Vedic knowledge, the original word *praṇava,* has been explained in *Śrīmad-Bhāgavatam.* The conclusion is that the *Brahma-sūtra* is explained in *Śrīmad-Bhāgavatam.*
