Early on Mahalaya morning, Kolkata woke up to a familiar ritual. Birendra Krishna Bhadra’s classic Mahishasura Mardini recitations echoed from radios and TVs in every home. You could hear those iconic chants drifting across every corner shop in the city.
By evening, the festivities and all the action shifted to Eden Gardens. Traditional music filled the air during the stage program. Speeches by distinguished guests, including the Chief Secretary, the Chief Minister and the Governor, marked the official opening.
The night brought a major milestone on the field. Over 3,000 dhakis, traditional Bengali drummers, gathered to set a new Guinness World Record. They played together in one massive beat. As their drumming thundered through the stadium, thousands of LED drones rose into the night air.
BotLab Dynamics brought the aerial show to mark the start of Durga Puja. The drone display acted as the start of the festivities in Bengal. It transformed dawn radio memories into a visual story high above the skyline.
Bringing Agomoni to Life in Light
For families across Bengal, the Durga Puja festival does not begin at a busy Durga Puja pandal. It starts at home with Agomoni. This tender tradition follows Goddess Durga. She returns to her earthly home as the beloved daughter, Uma. The performance translated that quiet emotional connection into light and sound.
The soundtrack opened with the solemn chanting of Chandipath. As those sacred recitations filled the stadium, soft white lights scattered across the dark sky. They formed swaying stems of Kaash Phool. This wild autumn grass signals the start of the Durga festival in Bengal.
As the glowing petals moved apart, the flute notes of Bajlo Tomar Aalor Benu took over. The story of Durga Maa began to unfold in the sky, one formation at a time.
Mangal Ghot: A sacred pot took shape in bright LED lights above the crowd. The Mangal Ghot, a symbol of purity, marked the invitation to Durga Maa pooja.
A Divine Lotus, Cradled in Alta-Adorned Hands: A pair of hands with red alta on them appeared, gently holding a blooming lotus. The image brought to life the feeling of Durga Maa returning to her ancestral home as a daughter.
The Looming Rakshas Threat: The mood changed as Mahishasura's silhouette appeared in the sky. Bursts of light and loud sound effects added to the tension. The threat was clear, and the story moved towards the battle.
The Divine Transformation of Uma to Durga Maa: The chants of Aigiri Nandini filled the stadium. Uma's outline slowly took the form of Durga Maa, with ten arms holding divine weapons. The transformation marked the arrival of Shakti, ready to confront Mahishasura.
The Awakening of Shakti: The lotus lit up, growing brighter before a mandala appeared around a trishul at its centre. The sequence brought the focus back to the divine power of Shakti.
Durga Maa on Her Divine Mount: Durga Maa appeared riding her lion, her full form spread across the night sky. The image carried the story closer to its final confrontation.
The Victory over Mahishasura: The final battle formation showed Durga Maa defeating Mahishasura. It was the moment the story had been building towards, bringing the age-old tale of good triumphing over evil to the sky.
As the festival progresses toward Maha Ashtami, these central stories remain at the heart of Bengal's devotion.
The Sacred Moment of Chokkhudhaan
In every Durga Puja pandal, artisans treat Chokkhudhaan as the most sacred step before opening their doors. It is the moment when a master sculptor paints the eyes onto the clay idol. This final stroke brings the deity to life.
BotLab Dynamics recreated that ritual in the open sky. Light sweeps moved across the dark backdrop like deliberate brushstrokes. They slowly uncovered the wide eyes and the trinayana (third eye) of Goddess Durga. Soft traditional chants replaced the drums. The crowd looked up in silence as the words Shubho Mahalaya lit up the night.
Why Sky Storytelling Moves People
A drone show works like a giant moving illustration in three dimensions. The team syncs light formations with Bengali narration, traditional music, and dramatic audio cues. The open air becomes an active storyteller as thousands of people standing in one place experience the same emotional beat together.
The engineering team at BotLab Dynamics saw this same collective feeling at the Ambaji Temple Drone Light Show. Light figures in the night brought a deep sense of shared wonder to massive crowds. It is a modern format. It fits the grand scale of Durga Puja perfectly.
Looking Ahead: From Kolkata to Digha
The performance at Eden Gardens was the opening act of a multi-city plan across Bengal. Traditional almanac calculations note that Goddess Durga arrives on a horse this year. She departs on a boat.
To reflect that journey, the next show moves to the coastal town of Digha on Maha Panchami. Staging the performance in the CM’s constituency connects major city events with regional coastal communities.
Soon, pandal hoppers will step out across the state. The display over Eden Gardens gave Kolkata an unforgettable start to this year's festive season.
