Prose
S. B. U. II. 11
In plain words
This entry is not a verse of Śaṅkara's. It is a stray page reference -- "S. B. U. II. 11" -- that the printed edition dropped into the running text, most likely pointing a reader to a section number elsewhere in the book. There is no Sanskrit prose here to render into English.
