The Main aspects of ThaiPoosam festival are Sakthi Malai(IRUMUDI), Velvi and Jyothi Darshan.

Sakthi Malai (Irumudi) is a very important occassion to AMMA devotees. Sakthis put the sakthi malai in their mandrams and will observe fasting. Then, they come to Siddhar peetam and submit their Irumudi by doing the Abhishegam to Suyambu. AMMA has given a chance for all of us to do the Abhishegam to HER twice a year. One is during the Irumudi and the other is at Aadipooram. So we all must use this opportunity and get the blessings of AMMA.

Arul Thiru Adigalar was born on the 3rd March 1941. Adigalars's day of incarnation was first celebrated on 3rd March, 1983. Normally all the other festivals at Siddhar peetam maintains a God - Devotee relationship, but the grand festival celebration on every 3rd March ie AMMA's Avathar day is celebrated as the day of Guru - Disciple relation.

The devotees, as a sign of gratitude to their Guru, presented Him, on His birthday with a Golden Chariot. On His Avathar day Adigalar sits on the chariot for some time to satisfy HIS devotees and joins thousands and thousands of devotees in a procession, which starts from His house and ends at Siddhar peetam. On HIS birthday, HE garlands HIS parents and worship them and asks for their blessing.Do not forget your Mother and Guru is AMMA's oracle.

On HIS birthday, the devotees perform Padhapooja to Adigalar, soon after this HE comes to the Putrumandapam and sits on the well decorated floral stage, to give Darshan to the public, starting in the morning till evening.

Since 1995, AMMA's Avatharday is being celebrated for three days. On 1st March the members of various commitees of Siddhar peetam and the devotees perform Padha Pooja to AMMA. On the 2nd day students of the various educational institutions perform cultural programmes.On the 3rd day the public darshan of Adigalar starts from the morning till evening with a very grand Annadhanam to all.

This festival usually falls during the April-May period as per the Gregorian calendar, however as per the Tamil calendar (ancient language of India), the festival is celebrated on the full moon day in the month of Chithirai (Tamil month of May).

This festival is signified by the large scale kalasa velvi pooja which is held at the Siddhar Peetam and thousands of yagnas performed by devotees for their welfare and of the world at large.

The three important aspects of Aadipooram festival are:

• Serving Kanji(Gruel)
• Devotees themselves doing Milk Abhishegam to Swayambu
• AMMA Herself in the form of Arul Thiru. Adigalar performing Angapradhakshanam.

Serving Kanji(Gruel) is a special offering to AMMA. About this AMMA has said in her oracle “Son, the kanji you have brought here as an offering is not an ordinary one. To me it is the GOD's divine food(Amirtham). The kanji(gruel) is not made up of rice and ghee, but carries with it, the invaluable love, affection and devotion of my devotees.” Thousands of people from all over bring this gruel and take it around the Siddhar peetam and the gruel is served to all.

Milk Abhishegam to Swayambu is an important event on the day of Aadipooram. This is one of the 2 special days each and every one gets the opportunity to enter the sanctum sanctorum and do Abishegam to AMMA on their own hands.

AMMA believes, that people with never ending problems get theirs resolved by performing the milk abhishegam and those who wish to attain spiritual growth and development can also achieve it by doing this abhishegam to AMMA.

Angapradhakshanam of AMMA is the crowning glory of Aadipooram festival. Arul Thiru Adigalar reaches the sanctum sanctorum after his bath and stands in front of the Swayambu. In a fraction of second, Adigalar becomes an incarnation of AMMA. In this trance dental state, "AMMA" who seems to resemble a cobra at this moment, jumps from the sanctum sanctorum to the mandapam, which is six feet away. It is beyond the powers of human form and performance. AMMA goes around the Siddhar peetam, in Angapradhakshanam.This is beyond human imagination and it is a "miracle".

AMMA believes that doing angapradhakshanam on the Siddhar peetam, saves people from their fate and destiny. So, hundreds of devotees do the angapradhakshanam on everyday to cleanse themselves of their sins and attain greater spiritual strength.

Navarathri is a key festival celebrated over nine days.

On the first day, Amma lights the lamp called Agandam filled with three oils; neem, coconut and sesame. Prior to lighting the lamp, Amma goes around the Siddhar peetam three times, then enters Putrumandapam to worship the Goddess, during which time Adhiparaksathi transcends into him. In that divine state, Amma then enters the sanctum sanctorum to perform rituals to the Swayambu, after which the wick of the Agandam is lit with Her mouth. At that point in time, Amma’s face and body almost appears to resemble a dancing cobra.

The Agandam burns for nine days continuously, while devotees pour the tri-oil into the lamp, worship the light emanating from the flame and breathe in the holy smoke.

Amma, in Her oracle declared that, ‘Agandam has the power to help man out of his crisis, which is the outcome of his fate and destiny’.
