Bhagavad Gita · Chapter 10: The Divine Glories

Bhagavad Gita 10.23

rudrāṇāṃ śaṅkaraścāsmi vitteśo yakṣarakṣasām | vasūnāṃ pāvakaścāsmi meruḥ śikhariṇāmaham ||

Among the Rudras I am Shankara; among the yakshas and rakshasas I am Kubera, lord of wealth; among the Vasus I am fire; and among mountains I am Meru.

Modern context

Among the Rudras, Shankara, the auspicious one; among nature spirits, Kubera, lord of wealth; among the elemental gods, fire; among mountains, Meru, the cosmic mountain at the centre of the world. Notice that Shiva is named here as a glory of Krishna. The Gita does not set the great deities against one another. They are different windows onto one light.
