This is one of the very ancient and rare temple in Kerala where Muhurthi is worshiped (No Idol). The origin of the Temple can not be traced through records.  But it is founded some six hundred years ago for the spiritual benefit of Ammachi Veedu family, an ancient aristocratic family in Quilon (Kollam).  It is believed that the Diety is the Guru of Dharma Sastha of the Temple named Shasthamkotta Temple about 35 kms meters away from the Ammachi veedu.  On the basis of a marriage ceremony Lord Dharma Sastha with pleasure entrusted the Diety to one of the Karanavans, more who is now worshipped in the Temple as ‘Brahma Rakshas’, on the right hand side of the Diety.  Since the Diety has the position of a Guru, the members of the Tarawad is prohibited to enter into the premises of Shasthamkotta Temple.  But on all auspicious occasions poojas have to be performed there, and get the blessings of Dharmasastha. The most important aspect is that the ‘Garbhagrah’ of this temple is only 4 x 4 x 6 width, breadth and height. There is a Peedam over which the diety is installed. Two ‘Coanches’ are placed over the Peedam and recently the Peedam is covered by silver plate and the two coanches are placed in golden covers. The diety is considered as powerful and the devotees without caste colour and creed worship in the temple.  Adjoining the temple there is a Sarpakavu where in Parappooramma Bhagavathi is installed and Nagaraja, Nagayakshi and Naga Kanyaka are also there.  The annual ‘Noorum Palum, and Sarpabali is performed by Tantri of ‘Pambummekkattu Illom of Mala’.So also the Tantri of the main temple is Sreedharan Namboodiri of Puthumana Illom.  The main Upadevathas are Ganapathy, Rektha Chamundi, Paramparu, Yakshi, marutha, Rekshus, Gandharvan, Vethalam, Yogeeswarans.  Apart from there another diety which is placed out side the temple premises is ‘Ginnu’,  worshipped by Muslim community. There is no exact date on which the festival is to be conducted.  The annual festival falls on Dhanu of every year but it is to be done after the Mandala Pooja is over.  This fact gives ample proof that the diety has some relation with Dharmasastha and the members can not go on pilgrimage to Sabarimala temple.  10 days festival is conducted in the temple without any financial support from the public.  No donation is solicited for the purpose.  On the 10th day the Karanavan conducts the pooja in the Kalam specially prepared for the purpose and boiled Ninam is offered to the diety.  This is a rarest phenomina available in the temple. The diety is worshipped by the name Moorthy Amma, which denotes the absence of an idol.  Every year Sahazrakalasam is conducted. The desires of the people will be materialised in all sense by the Mother.  There is a Sree Chakra prathishta in the temple on the left side of the Diety.  This Amma can be worshipped in any form, it is on the basis of mental desire of the worshippers. The temple is always thronged by devotees coming from different parts of the country without caste and creed, seeking the blessing of goddess. It is their strong belief that all their prayers will be granted by the divine mother. Many unmarried girls and boys are said to have benefitted by the performance of special poojas in the temple and got good proposals. The devotees also have informed the Devasom about the removal of their various problems by the blessings of Goddess. The public at large is flocking in the temple for getting their diseases cured by the blessings of the deity. A large number of people from many places coming to the temple for the same purpose. Ganapathi Homam, Bhagavathy Seva, Muzhukkappu  to Ganapathy, Palpayasam, Vidyarambam, Thulabharam, Kunjoonu, Malarnivedyam, Meni payasam,  Abhishekas, Noorum Palum, Ayilyam Oottu, Panthirunazhi etc are the important offerings in this famous temple.
