The Great Miracle of this Holy Place is that it is one of the famous Shakti Pith of the Universe. It is one of the original source of the Supreme Cosmic Power of Universe. It is the symbol of Supreme Cosmic Energy and hence there is no idol or picture in the Nij Mandir or Temple of Shri- Arasuri Mata Ambaji, but there is simple a cave like Gokh in the inner wall, in which a Gold Plated Holy Shakti Visa Shree Yantra is visible, but it was neither photographed in past nor can also be photographed ever in future too. But this Holy Gokh of Mata Ambaji with Shakti Yantra is used to be so decorated by the Pujari of this Holy Place that one can see it or imagine it as an idol of Mata Ambica. Again on each day of a week , Shri Amba Mataji's Gokh having this Holy Shakti Visa Yantra in its centre in the Nij Mandir is also decorated in such different way and manner that it may look one of the famous Incarnations of Goddess Nav Durga, sitting on its special Vahan.
Thus the Visa Chakra Holy Yantra, in a symbol of one of the above said Maha Devi Shakti Swaroopi, sitting in the Holy Gokha of Nij Mandir with tradition Shringar is worshiped on the relevant day with Sodashopachar Shastrokta Vidhi i.e., with all kinds of Vedic rituals and traditions by the priests or pujaries of Sidhapur, belonging to the ancient priests of the Temple of Ambaji i.e. Pujari Kul of Bhatt Family, together with all other daily and occasionally Puja, Devotions and Pilgrimage Offerings made by the pilgrims and tourists, under the direct supervision and administration of Shri Arasuri Ambaji Mata Devasthan Trust (SAAMDT).
The Visa Yantra in the Gokh of the inner wall of the Nij Mandir or Temple of Mata Ambaji is here worshipped and there is no idol of Devi Arasuri Ambica. A Gold Plated Holy Shakti Visa Yantra is fixed on a marble plate. The ornaments and holy attire are placed in such a way and manner that it looks like an idol of Mataji Ambaji. As per the Indian Scriptures and legends, this Gold Plated Shakti Visa Yantra is entirely a holy Shree Yantra. This golden Yantra has kurma back with gold and is connected with that of the original Yantras of Nepal and Ujjain Shakti Piths and has 51 letters therein this Shakti Shree Yantra. It is also believed that the worship of this Visa Shree Yantra is done only after tying a bandage on the eyes as it is prohibited to look at it. This Yantra is also worshiped ritually with Nav Chandi Yagna and with other traditional Sodashopchar Puja, on each eighth day of every month. It is also considered as Kalpavruksha, because of which this Devasthan has also florished like anything. So it is strictly prohibited to take any snap or photographs of Nij Mandir or of the Holy Idol of Mata Ambaji.
Moreover on each 8th day of each month as per the Indian Vikram Samvat year, in other words, on each Sud Atham of each month, a traditional Nav Chandi Yagna as per Vedic Rituals is also done by Shri Arasuri Ambaji Mata Devasthan Trust itself , through Brahmins, in front of the Nij Mandir near Chachar Chowk, where a huge Yagna Shala is also constructed. Whereas on each month of Asho, Chaitra, Maha and Ashadh, the worship of Jagadamba and Visa Shakti Yantra is carried out by means of Satachandi Yagna ,during the time of Nav Ratri.
The Shringar of Mata Ambaji here in the Nij Mandir is changed according to different Darshan hours, such as it is of a virgin Kumarika Devi during morning hours, that of a blonde young woman during noon hours and that of an old lady during evening hours every day. In the main temple the silver sandals or Paduka of Mata Ambaji are also worshiped. There is also a big idol of a Holy Lion in front of Gokha of Mata Ambaji, and the devotees use to worship this holy lion with Kanku Puja, which is also a traditional symbol of Indian married woman who use to keep Kanku on the front of the middle of her head and hairs, for the sake of her happy matrimonial life.
There is no discrimination of any caste, creed or religion in front of Mata Ambaji. The Darshan of Mata is available to all kinds of people. But nobody is allowed to worship the Holy Yantra, except the priests of the temple and the family members of the former rulers of Danta State, after taking ritual baths and in silk apparels only. There is always worships of Goddess of Mata Ambaji with Durga Path, Mantras and stotras of Bhawani.
Usually Mata Ambaji is worshiped with Arti Puja & Naivedya everyday in morning and evening during Sandya Kal, except in summer time when Mataji is worshiped with Three Arti Puja & Naivedya every day. Moreover there is a special arrangement for Annakoot and Thal of Devi Bhagawati, for which Shri Arasuri Ambaji Mata Temple Trust and the priest Bhattji makes all the necessary arrangements at the request of any devotees, seeking to perform this Special Seva of Annakoot and Thal of Devi Bhagawati.
There is also an Akhand Divo - a Holy Lamp in Chachar Chowk, which has been burning since many years i.e. since the period of Akheraj , a merchant and the devotee of Mata Ambaji as per the legend. The same Holy Lamp is still burning in front of Mata Ambaji and the devotees use to fill Ghee therein and keep it burning before Mataji.
The Main Temple of Ambaji is short and small but there is a huge Mandap and there is a Holy Gokh of Mataji in the Garbh- Gruh, and in front of this there is a big Chachar Chowk. So Mata Ambaji is also known as Chachar Chowkwali too. The ritual worships of Ambaji is usually performed in this Chachar Chowk, and during the period of Navratri the devotees use to play and enjoy Garba of Mata Ambaji in front of the main temple in this Chachar Chowk, which is also illuminated with colorful lightings from all corners, as it is so done during the Festivals of Ambaji Devasthan.
