Ambubachi Mahayog

The Ambubachi Mahayog is an annual festival held at the Kamakhya Temple in Guwahati, Assam. This event is celebrated during the Hindu month of Ahaar, typically falling in June or July. The festival draws millions of pilgrims and spiritual seekers who come to honour the divine feminine energy represented by Goddess Kamakhya. The year 2025 saw over 1.5 million attendees, denoting the festival’s significance and the increasing interest in Tantric practices.
Significance of Kamakhya Temple
Kamakhya Temple is one of the most revered Shakti Peethas in India. It is believed to be the site where the yoni of Goddess Sati fell after her dismemberment. This temple uniquely celebrates menstruation as a sacred act rather than a taboo. The festival acknowledges the goddess’s annual menstrual cycle, symbolising fertility, creation, and the cyclical nature of life.
Rituals During Ambubachi
During the festival, the temple is closed for three days. The sanctum sanctorum is draped with a white cloth over the yoni stone, symbolising the goddess’s seclusion. No prayers are offered during this time, and agricultural activities are paused. This period of rest is followed by a grand reopening, celebrating the goddess’s renewal with rituals and the distribution of Rakta Bastra, a sacred red cloth.
Rakta Bastra – The Sacred Cloth
The Rakta Bastra, which translates to “red cloth,” becomes a powerful symbol during the festival. Once the white cloth is removed, it is replaced with a red one, representing the menstrual fluid of the goddess. Devotees consider this cloth imbued with divine energy, often treating it as an amulet for blessings related to fertility and prosperity. However, concerns about the commercialisation of this sacred item have emerged, with temple authorities warning against counterfeit claims.
Symbolism of Menstruation
The Ambubachi Mahayog redefines menstruation as a sacred event. In a culture where menstruation is often stigmatised, this festival celebrates the female body and its role in creation. The red cloth serves as a reminder of the power of femininity and the importance of honouring natural cycles. It transforms a traditionally taboo subject into a revered aspect of worship.
Tantric Practices and Global Interest
Ambubachi is also for its association with Tantric traditions. During the festival, practitioners engage in rituals aimed at spiritual awakening and esoteric knowledge. The event attracts not only Indian devotees but also international spiritual seekers, denoting a growing global interest in ancient practices and goddess worship.
Scientific Perspectives
While many view the Rakta Bastra as containing literal menstrual blood, temple authorities clarify that it is symbolic. The nearby Brahmaputra River is also said to turn reddish during the festival, which scientists attribute to natural phenomena rather than divine intervention. These misconceptions illustrate the need for a nuanced understanding of the festival’s symbolism.
