Shakti Ganapati is a concept wherein Ganesha is accompanied along with Shakti.
There are some modern temples especially in Southern India, which attribute Shakti as wife of Ganapati.
Even, the deity has Shakti (sitting on the left thigh of Vinayaka, i.e. Vama bhaga, which is normally attributed to place where wife is associated).
So, is there any proof in the Puranas regarding Shakti to be consort of Ganapati or Ganesha?
