parama -- exalted; asane -- on a seat; asinam -- sitting; krishna -- Draupadi; krishnam -- Krishna; anindita -- blameless; nava -- newly; udha -- married; vridita -- shy; kincit -- somewhat; sanaih -- slowly; etya -- approaching; abhyavandata -- offered her obeisances.
Srimati Draupadi was so devoted to Krishna that she herself was called Krishna, which is the feminine form of the name, and Arjuna was also called Krishna because of his devotion to the Lord. Similarly, the devotees of the modern Krishna consciousness movement are often called "the Krishnas." So it appears that the custom of addressing Krishna's devotees by His name has a long history.
