manasa me suta yusmat-
cerur vihayasa lokal
brahma uvaca—Lord Brahma said; manasah—born from the mind; me—my; sutah—sons; yusmat—than you; purva-jah—born previously; sanaka-adayah—headed by Sanaka; ceruh—traveled; vihayasa—by traveling in outer space or flying in the sky; lokan—to the material and spiritual worlds; lokesu—among the people; vigata-sprhah—without any desire.
Lord Brahma said: My four sons Sanaka, Sanatana, Sanandana and Sanat-kumara, who were born from my mind, are your predecessors. Sometimes they travel throughout the material and spiritual skies without any definite desire.
When we speak of desire we refer to desire for material sense gratification. Saintly persons like Sanaka, Sanatana, Sanandana and Sanat-kumara have no material desire, but sometimes they travel all over the universe, out of their own accord, to preach devotional service.
