This is a mysterious trident, only wishing to see is complete

Mount Abu is the only hill station in Rajasthan. Here is Guru Shikhar Parvat. This mountain belongs to the Aravalli range. The penance of Lord Dattatreya is present on this Guru Shikhar. It is believed that Lord Dattatreya meditated here several thousand years ago.
Lord Dattatreya is the incarnation of Tridev i.e. Lord Brahma, Vishnu and Mahesh. Dattatreya is both God and Guru. That is why he is also referred to as Gurudevadatta. There exists a cave where Lord Dattatreya meditated. The divine trident of God is still present here. It is said that a devotee who sees this divine trident is fulfilled his wishes.
Adhar Devi Temple:
Mountabu itself houses the temple of Arbuda Devi, Adhar Devi. In fact, Abu Dhrubhans of Arbuda is Abu, after whose name Mountabu was found. There is a temple of Arbuda Devi on the Arbuda mountain, which is the sixth Shaktipeeth among the 52 Shaktipeeths of the country. Arbuda Devi is the form of Katyayani out of the nine forms of Goddess Durga who is worshiped on the sixth day of Navratri.
