再稍微找一下, 可以找到不少Gadhimai festival 或 Gadhimai Temple

http://en.wikipedia.org/wiki/Gadhimai_festival

About 2 million people participate in the festival, Madheshi and more than 80% of the devotees are the people from the Indian states of Bihar and Uttar Pradesh. Attending the festival in Nepal circumvents the ban on animal sacrifice in their own states.[2][3] Participants believe that animal sacrifices to the Hindu goddess Gadhimai will end evil and bring prosperity.[4][5]

但也不排除英語系國家的人把地名當神名的情形, 或是譯音問題
也有可能是尼泊爾把當地的神與Durga結合的產物
在神話裡面, 不同的神的故事混在一起是很常見的, 像度母混觀音
