Where the current temple's sanctum sanctorum stands today, there was only a neem tree in 1960's. Unlike every other neem tree, which bear bitter tasting fruit, this tree secreted and dripped a sweet nectar. Residents of that village found that they had a urge in their mind to taste this nectar whenever they passed by this tree. Since many passers reported of curing their illness and diseases after tasting this nectar, the word spread swiftly to entire village and its neighborhood. So it became a customary for these villagers to take a drop of this nectar to ailing friends and relatives. They treated this as a medicinal tree and protected it from grazing cattle and wood cutters.

In 1966, a severe storm uprooted this neem tree, which exposed the Swayambu underneath to the villagers for the first time. Swayambu means "A self emerging, naturally formed oval shaped object (carved of rock)". People built a small hut on top of this Swayambu and conducted poojas (prayer rituals) to it.

This place is known as Siddhar Peetam ("Siddhar" in Tamil language means enlightened or evolved souls. "Peetam" means throne. Thus Siddhar Peetam means The Throne of Evolved Souls or Great Spiritual Masters/Gurus) where 21 Siddhars are laid in Jeeva Samaadhi.

Swayambu alone was worshipped for many years. The idol of Mother AdhiParaSakthi was installed later in the sanctum sanctorum on November 25 1977. The idol of beautiful Mother is three feet tall, seated on thousand-petal lotus seat, with Her right leg folded and the left leg resting on the lotus petals. The thousand petal lotus has significance in meditation. In this idol form, She holds the bud of a lotus in Her right hand, the mudhra (sign) of knowledge in Her left hand and with Her hair plait and knotted upwards like a crown.

The shape of this idol is very different from those described in the codes of sculpture. The Mother wanted the idol to be in this form and so ordered through Her Oracle to one of the devotees to create it. The shape and form of this idol cannot be seen anywhere else.

The layout of the Temple is as follows: The OM Sakthi Stage at the entrance. On the highway in front of the Siddhar Peetam there is a stage with the mantra of "OmSakthi" on it. Soolam (Trishul) of the Mother is erected on this stage. The devotees entering the Peetam to worship the Mother, first go round this stage thrice and then enter the Peetam. Since the AdhiParaSakthi is the Mother Origin of everything, there is no NavaGrahas (9 Planets) that are usually found in all other Hindu Temples. The Mother has ascertained, "Those who surrender to me, need not pray to the planetary Lords. They are my officers who carry out the work of implementing my Law of Karma.

The Sanctum Sanctorum faces the entrance where OM Sakthi stage is located. Inside this sanctorum is the Swayambu and Mother's idol. The sanctorum is only about 10X10 feet room. Amma has revolutionized the concept of spirituality by letting everybody irrespective of caste, creed, religion, language, nationality, social status, gender, education, etc., to enter the sanctum sanctorum and perform the daily rituals and prayers to the Mother AdhiParaSakthi. Women can enter the temple even during their periodic menstrual cycle a taking bathe.

Although, Siddhar Peetam is called the AdhiParaSakthi Temple, there are no religious codes followed. There are no other Gods or Goddesses as found in other Hindu Temples. People belonging to all religions visit this Temple all the time. They recite their own religious Holy Scriptures such as Bible, and Quran. As Amma says, whichever scripture we read, whatever mantra we recite, everything is received only by Amma. And Amma is the one who disposes them. The visiting devotees are not required to convert their religion.

One of the unique features of this Temple is that it does not have priests to perform or conduct daily prayers unlike other temples and churches. The devotees themselves are allowed to enter the sanctum sanctorum all the time and they can perform archanas and abishekams in accordance with the procedures laid by the Mother AdhiParaSakthi through Her Oracles. Maha yagnas or velvis are conducted by volunteers here.

The Daily Routine:

The people who serve in the Siddhar Peetam are normally the devotees clad in red dress. They come from outstations, render services and return home. To serve at the sanctum sanctorum, each one of the weekly worshipping centers (mandrams) is alloted a day and informed sufficiently early. Accordingly, all mandrams compete with one another in rendering the best service. Every day Abhishekam at the sanctum sanctorum takes place at 4:00 AM in the morning. After this, idol of the Mother is decorated followed by aradhana. The Mother's blessed prasadam (proceeding of the prayer) is then offered to the devotees. Everyday around 11:00 AM free food is distributed to all visiting devotees. Besides, on the new moon and full moon days, Adigalaar is given a special welcome and the free food distribution is done on a large scale.

AMMA is very fond of cleanliness. She resides in a clean inner soul and a clean appearance. In the same way, the Temple and its surroundings are always kept clean by volunteers.

Nobody prevents the people from worshipping the Mother AdhiParaSakthi inside the sanctum sanctorum. Also, it is FREE OF COST unlike other temples in India, where money must be paid to conduct prayers.
