indram - as Indra; naḥ - our; tvÄ - to You; abhiá¹£eká¹£yÄmaḥ - we shall perform the bathing ceremony of coronation; brahmaá¹‡Ä - by Lord BrahmÄ; coditÄḥ - ordered; vayam - we; avatÄ«rṇaḥ asi - You have descended; viÅ›va-Ätman - O Soul of the universe; bhÅ«meḥ - of the earth; bhÄra - the burden; apanuttaye - in order to alleviate.
Surabhi makes it quite clear in this verse that she has had enough of the leadership of imperfect demigods like Purandara (Indra), and now she is determined to directly serve the Supreme Lord. Since BrahmÄ has ordered her, her attempt to coronate Lord Kṛṣṇa as her personal Lord is authorized by higher authority. Moreover, Lord Kṛṣṇa Himself comes down to the earth to relieve the burden of self-destructive, mundane administration, and thus it is perfectly consistent with the Lord’s own purpose that He become the Lord of Surabhi. Since the Lord rules millions of universes, He can certainly take care of mother Surabhi.
In fact, Surabhi wanted to bathe the Lord for her own purification, and she earnestly makes her proposal to ViÅ›vÄtmÄ, the Soul of the universe, ÅšrÄ« Kṛṣṇa.
