This holy spot near Patnitop is situated at an altitude of 1225 mtrs., about 120 kms. from Jammu. The shrine is visited pilgrims on the full moon night of "Sawan" (July-August) to worship the "Trishul" (trident) and a mace which is said to belong to Lord Shiva. The Devak stream originates at Sudh Mahadev and disappears among the rocks a few kilometres down strean. This is a small temple of Lord Shiva. During July - August a fair is held here with 3 days of music, singing and dancing. It is situated at a distance of 8 kms. from Khud or Patni Top.
According to a popular legend, it is believed that Lord Shiva who was in his Samadhi (deep meditation) shot his big Trishul (trident) to protect his consort Uma startled suddenly by her loud cry. However, it was Shiva's devotee, Sudheet who approached Uma to pay his respectful obeisance and since he was a demon in his previous birth, his demoniac looks frightened her and she made a loud shriek. The trident however killed Sudheet. Shiva realized his mistake and offered to resuscitate him but Sudheet preferred the death given by Lord Shiva Himself. Touched by his devotion, Lord Shiva prefixed his name to the place forever and the broken trident in three pieces, is still installed in the temple. The Devak stream originating at this place disappears enchantingly among the rocks a few kilometers downstream. The temple has a natural block marble `lingam` and goddess Parvati mounted on Nandi, the bull. The `Dhooni` (sacred fire) immortalises the spiritual accomplishments of Baba Roop Nath who is said to have attained Samadhi here. People are of the faith that the fire is burning since time immemorial, ever since Baba Roop Nath resided here.
