It is one of the most important observances of Ashada Masam 2026 — a heartfelt thanksgiving to the Mother Goddess for health and protection during the monsoon.

Significance

Bonalu (from "Bhojanalu", meals) is an offering of gratitude to Ammavaru — the fierce, protective Mother. Historically tied to warding off epidemic disease in the monsoon, it is a women-centred festival and an official Telangana state festival, expressing devotion, community and thanksgiving.

Story & Origin

The tradition is widely traced to 1813, when a plague struck the twin cities. A military battalion from Hyderabad, stationed near Ujjain, prayed to Goddess Mahakali and vowed to install her if the epidemic ended. On their return, with the disease subsided, they installed the deity (Ujjaini Mahakali, Secunderabad) and began offering Bonam in thanksgiving — a practice that has continued ever since.

How the Diaspora Celebrates Bonalu

Telangana and Telugu associations in the USA (TATA, NATS, ATA), UK, Australia and the Gulf organise community Bonalu with processions and Mahakali puja. At home, families prepare a small Bonam with a decorated pot and neem leaves and offer it at the nearest temple on an Ashada Sunday — apartment-friendly and meaningful.
