6.11.20

nanveṣa vajrastava śakra tejasā harerdadhīcestapasā ca tejitaḥ /
tenaiva śatruṃ jahi viṣṇuyantrito yato harirvijayaḥ śrīrguṇāstataḥ //

20. O Indra, this Vajra is not indeed sharpened and strengthened with thy power; but it is so with Hari's energy and the tapas of Dadheechi; slay thy enemy with the same Vajra which is energised with power by Vishnu. On whatever side Hari stands, (on that side) victory, fortune, and meritorious qualities will be.
