At North-West corner of Maheswaram Sri Sivaparvathi Temple there is Mahalingam having 111feet height. Mahalingam at Maheswaram Temple is the world’s highest Sivalingam. Mahalingam is unique in its style of Construction. Mahalingam has plenty of unique peculiarities. One of the peculiarities is its style of construction. Devotees can enter into this Mahalingam. The construction of this Sivalingam is based on Shadadharam. There are 6 different meditation halls representing different chakra (Adhara) in human body. Those chakras are Muladhara, Swadhishthana, Manipura, Anahatha, Vishuddha and Ajna. Muladhara is the seat of physical vitality and the fundamental urge to survive. It regulates those mechanisms which keep the physical body alive. It is the chakra whose main aspect is innocence. It is symbolized by a lotus with four petals. Swadhishthana is where we develop an inward sense of self and an outward awareness of others - ego, sexuality and family. The feelings of other people are directly perceived through mastery of this chakra’s energy. It is symbolized by a lotus with six petals within which there is a crescent moon. Manipura is located at the centre of the body. It is the place where physical energy is distributed. It is the center for unrefined emotions and personal power. It is the center that gives us the sense of complete satisfaction and contentment. Our creativity is fueled by our power of will. It is symbolized by a downward pointing triangle with ten petals. Anahata is the centre of real, unconditional affection, spiritual growth, compassion, devotion and love. It is the bridge connecting the lower and higher energies of our being and is the place where our Spirit, our true Self - free and independent resides. Anahata is symbolized by circular flower with twelve petals. Vishuddha is the centre for communication, self-expression and creativity. This is where the inner voice of one’s truth is expressed. It is the chakra of diplomacy of pure relationships with others. It is represented by a silver crescent within a white circle with 16 petals. Ajna is the seat of intuition and direct spiritual vision; it is here that we visualize things through our “third eye” of intuitive knowledge. The opening of the third-eye corresponds with spiritual awakening. It is the chakra of forgiveness and compassion. It is symbolized by a lotus with two petals. Meditation halls representing Muladhara, Swadhishthana, Manipura, Anahatha, Vishuddha and Ajna are coloured Red, Orange, Yellow, Green, Blue and Indigo respectively.
In addition to the 6 meditation halls there exist another 2 halls, one at the bottom and other at the top of the Mahalingam. Devotees are allowed to meditate at each meditation hall by knowing about and concentrating at symbols of each chakra present there. Through meditation at Mahalingam, devotees can attain self realization (“Aham Brahmasmi”). In the Prayer hall (at the bottom of Sivalingam), there is a large Sivalingam. This is for the devotees to realize the fact that one should worship his own god by himself. Here Devotees themselves can worship Lord Siva and can proceed to the next six meditation halls to meditate by concentrating on symbols of each Adhara and finally devotees can reach Kailasam which is at the top level of Mahalingam. There each devotee can reach at the Sannidhi of Sri Sivaparvathi at Kailasam. At this highest level one can realize the ultimate truth “Aham Brahmasmi”. Way to the top level of the Mahalingam is spiral shaped and is surrounded by a cave like atmosphere and plenty of carvings (of Monks) pertained to meditation. Inside Mahalingam, 108 different Sivalingam can be seen along with 64 forms of Lord Siva. The serene atmosphere inside the Sivalingam gives a rich spiritual experience to each devotee who visits Maheswaram Sri Sivaparvathi Temple.
