This temple is at Chathanoor, Edanadu, in Kollam district. According to legends, the area where the temple stands today was a dense forest with many holy trees. The kavu was there till around 50 years ago, and the remains of these trees could be seen there. A Sanyasin named Koshnamuni used to live there. Later, some brahmins from the northern side of Travancore came by boats and settled at Kavanaappally. They entered into agricultural cultivation there, and the spot under the Rudraksha tree at the junction of the field and the kavu came to be used for storing products, as drinking water was more also available there. One evening, the Sanyasin who was in the kavu heard the voice of a girl. He went to investigate and saw a beautiful girl playing on the paddy heaped there by pouring it on her own head. He realised the divinity of the girl and offered worship.  He came to understand that the girl was Goddess Aadiparaashakthi, and she wanted to be consecrated there. Hence, it is believed that the Goddess at Koshnakavu is self-originated. The sanyasin spoke to the brahmins settled there, and they started worshipping the goddess. As the Goddess was first seen pouring paddy on herself, women and girls bring paddy from their houses and offer it to the Goddess on the day of star Thrikketta in the month of Medam. No elephants are brought to the temple for the festival. It is believed that once an elephant had trampled on the original idol of the goddess, which had become covered with soil, Madan Swamy, the protector of the goddess, had made the elephant remain fixed there. The sanyasin asked the owner of the elephant to offer a stick made of a particular tree trunk, and after that, he was able to take the elephant from there. The stick is brought out and kept on the platform where Madan Swamy is consecrated. As there were lots of serpents in the forest, they are still worshipped here even today. The sanyasin who first consecrated the Goddess there is now consecrated as Brahmarakshass. The head f of the brahmin community there is consecrated as Yogeeswaran. Around ninety years ago, the local people were able to get two acres of land for the temple. Later, as the forest was lost, small temples were built for Durga Devi, Ganapathy, and Mahadeva. Even these have become dilapidated and have to be renovated.
