Mahakaleshwar Jyotirlinga: The Mahakal Temple, one of the twelve Jyotirlingas, is a famous and venerated Shiva temple. The Shivling in this temple is supposed to be the only Jyotirling which faces south and hence it is known as Dakshinmukhi or the south-facing ling. It is the most popular and important temple of Ujjain. Every year on shivratri (claimed to be the Wedding day of Lord Shiva), there is a huge crowd of devotees for darshan. The same kind of public crowd can be seen in the month of Savaan, NagPanchami. On every Monday of "Savan", there is a huge procession for the Lord Shiva idol in the city attended by large numbers of devotees from across the India.
The powerful mahamrutyunjay mantra goes as -
"OM TRAYAMBAKAM YAJAMAHE SUGANDHIM PUSTIVARDHANAM, URVA RUKMIV BANDHANAN MRUTYOR MUKSHIYAMAMRTAT"
Mahakal derives its name from "kaal" meaning end of life - death; the word Mahakaal means Lord of Death.
Mahakaleshwar Jyotirlinga is one of the most famous Hindu temples dedicated to Lord Shiva and is one of the twelve Jyotirlingams, which are supposed to be the most sacred abodes of Shiva. It is located in the ancient city of Ujjain in the state of Madhya Pradesh, India. The temple is situated on the side of the Rudra Sagar lake.
According to Hindu scriptures, the universe is seen as consisting of three regions-the sky, the earth and the nether. Mahakal is Lord of the earth. Out of the 12 Jyotirlingas, only Mahakal is known as the Lord of the earth and Lord of the death (Kaalo k kaal Mahakal).
The idol of Mahakaleshwar is known to be dakshinamurti, which means that it is facing the south. This is a unique feature, upheld by the tantric shivnetra tradition to be found only in Mahakaleshwar among the 12 Jyotirlingas.
The idol of Omkareshwar Mahadev is consecrated in the sanctum above the Mahakal shrine. The images of Ganesh, Parvati and Karttikeya are installed in the west, north and east of the sanctum sanctorum. To the south is the image of Nandi, the vehicle of Lord Shiva.
Mahakal and Bhasma Arti: To attend Bhasma Arti in Mahakaleshwar is desire for every Hindu devotee. Mahakal and Bhasma Arti are synonymous with each other. Bhasma means ash. Mahakaleshwar is the only Jyotirlinga temple,where the Bhasma Arti is performed. Amidst vedic chants and strotras and sounds of cymbals, conchs and damru, the Bhasma arti is performed every morning (Except the second day of Mahashivaratri) from 4:00 am to 6:00 am to the Lord Mahakaleshwar. The Bhasma is prepared by burning dried cow dung. The mahant of the Akhil Bhratiya Mahanirvani Akhada or his representative offers the Bhasma.
The Bhasma Arti has its own protocols. During Bhasma Arti, no one can enter in the garbhagriha for worship wearing regular clothes. Only males wearing sola or silk clothe on their loins are allowed to enter into garbhagriha.At the time of Bhasma Arti,women are not allowed to enter inside. The devotees enjoy watching the great puja sitting in Sabhagruha just outside the garbhagriha. On next day of Mahashivaratri, the Bhasma Arti is held in afternoon after removal of the Lord's Sehra(bridegrooms' floral crown).This happens only once a year.
