And of the Rudras Shañkara am I; Vittesha of the Yakshas and Râkshasas; and of the Vasus I am Pâvaka; Meru of high mountains am I.
In plain words: Krishna says that among the Rudras, gods of storm and change, He is Shankara (Shiva). Among nature spirits and giants, He is Kubera (Vittesha), lord of wealth. Among the Vasus, gods of the elements, He is fire. Among tall mountains, He is the sacred Mount Meru.
