Parvateeshwar Temple, Varanasi

 Once Goddess Parvaty asked Lord Shiva the reason for all round happiness in Kashi. Lord Shiva replied that in various other places, if there is a Shiv Ling, there will be happiness in the area in the radius of about 10 miles. Whereas in Kashi there are Shiv Lings all over the place and thus the happiness is manifold.  This is one of the reasons for Kashi to be referred to as Ananda Van.  A person who installs a Shiv Ling in Kashi will enjoy ultimate happinessHearing this, Goddess Parvaty expressed her desire to install one Shiv Ling and sought permission from Lord Shiva.  If a pativrata wife (wife fully devoted to her husband) does a good job after getting due permission from her husband, she will be successful in her venture.  After getting permission, Goddess Parvaty installed a Shiv Ling, near Mahadev Ling, which came to be called as Parvateeshwar.

Kashi Khand, Chapter 93 states that a devotee who worships Parvateeshwar is cleansed of even the worst sin of Brahma Hatya. The devotee who regularly worships this Ling will himself take form of a Shiv Ling in Kashi after his death.

Special importance has been attached to Chaitra Month (March-April) Shukla Paksha Triteeya (3^rd day after Amavasya) and a devotee who performs pooja of Parvateeshwar on this day will get all round prosperity and will attain Moksha.
