Bhasma Aarti is a sacred ritual dedicated to Lord Mahakal performed inside the Garbhagriha (sanctum sanctorum) of the temple.
The priests collect the pious ash from the Dhuni, the sacred Akhand fire inside the temple. For your kind information, Dhuni keeps burning in the temple premise continually.
At the scheduled time of the early morning, the doors are opened, and Pujari starts the Pooja with a bath ritual by Panchamrit. Thereafter, the different kinds of sacred pastes and Chandan are offered to the Mahakal.
Then the sacred ash also known as Vibhuti in Hindi is brought on a silver plate, and then it is applied on the Shiva Lingam with deep devotion towards the deity.
In the background, some priests keep reciting the Shiv Mantras in Sanskrit during the entire session of Aarti.
When the melodious tone of Vedic mantras and visuals of Bhasma Aarti hits the soul, you feel an intense sense of spirituality in the atmosphere.
This highly spiritual Bhasma Aarti ceremony is performed early in the morning at 4 AM. Generally it lasts until 6 AM. As it's a dawn time session, so if you want to attend this, then you must wake up at 2 to 3 AM and reach the temple premises before 4 AM.
