Ardhanarishvara Linga is a very rare form of Shivling. Ardhanarishvara
Linga is half white and half red – some also have marks of trishul (trident)
and Damaru (glass drum). The description about the linga is only found in a
text credited to Hemadri, a 13th century who wrote books related to murtis,
temple architecture and construction.
In the Ardhanarishvara Linga, the white portion represents
Shiva and the red portion represents Shakti.
Ardhanarishvara Linga is part of the Bana Lingas and is
naturally formed.
There are carved Ardhanarishvara Linga – not naturally
formed but creations of sculptors.
The most famous carved Ardhanarishvara Linga is found in the
Elephanta Caves
near Mumbai, Maharashtra .
Naturally occurring Ardhanarishvara Linga are found in the Narmada River .
There are also some sacred spots in India with Ardhanarishvara
Linga carved on a single stone.
