OM (Aum)

The Padma Purana, Patala-khanda, states: “The name Mathura is equal to the sound of aum [omkara]. As Mathura contains the letters Ma, u, and a, so does the word aum. These three syllables make up the name of Mathura. Ma represents Maharudra Shiva; thu represents Vishnu; and ra represents Brahma. In this way Mathura is the topmost abode. Brahma, Vishnu, and Shiva always reside in Mathura in the form of deities.”
