meeting Thazampoo, (Ketaki flower or Screw Pine Flower), a kind of sweet smelling flower on the way, he inquired about Shiva's crown. He told Brahma that he had been floating down wards for centuries. Knowing the impossibility of seeing Shiva's crown, using Tazhampoo as a false witness, Brahma lied to Shiva the he had seen the crown of the column of fire. Enraged Shiva cursed Brahma that there won't be a any temple dedicated to him, and as for Thazampoo, it was unfit for worship at Shiva temples.

  According to the Shiva Purana,  Nageshvara Jyotirlinga is in 'the Darukavana, an ancient name of a forest in India. 'Darukavana' finds quoted in Indian epics, such as Kamyakavana, Dvaitavana, Dandakavana. Legend has it there was a demon named Daaruka, who  gave lots of troubles to the Shiva devotees, including one Supriya in his town of Darukavana, built under the sea and  inhabited by sea snakes and demons. The devotees and Supriya prayed to lord Shiva to save them from the demon and his unbearable atrocities let lose on them. They chanted the  holy mantra of Shiva and immediately thereafter the Lord Shiva emerged and  and killed the demon.  Daruki, wife of the demon, got special boons from Parvati, Shiva's consort and became a dominant figure in the forest Darukavana. Drunk with lots of magical power and arrogance, she moved the forest into the ocean and began treating the Shiva devotees and  the hermits shabbily, kidnapping them and jailing them, etc. Shiva's devotees were again subject to all kinds of mental pain and torture. Supriya, an ardent devotee made a lingam and asked the other  prisoners to pray to Lord Shiva. At last Shiva appeared in the form of Jyotirlinga and blessed Supriya with a weapon with which he called Daarukiki and other demons. Here the Shiva Lingam  reverentially prepared by Supriya is known as Nageswar and  goddess Paarvati is called Nageswari.

There are no Archaeological evidences suggesting the presence of Darakavana forest in ancient times; hence the location is a controversial one and  because of its  questionable location,  'Jageswara' temple in Almora, Uttarakhand is commonly identified as Nageshvara Jyotirlinga. This place - Darakavana has innumerable Deodar trees, perhaps, it is believed, the name  may be derived from it. The temple, built in North Indian temple architecture style, is visited by devotees from all over Gujarat and other places.
