In places where rain is crucial you'll probably find people of great faiths devoted to rain, the rainmakers and rainmaking cults. There are various cults around the world that practice or practiced some sort of rainmaking rituals. The native Indians of North America had rain dances and similar practices occurred and still do in parts of Africa including Malawi.
Khulubvi sacred shrine is located in Nsanje District, in the lower Shire Valley in Southern Region of Malawi, It is an important spiritual place among the people of Mang'anja tribe. It is a place where the Mang'anja worship the spirit of Mbona.
After her death the cult continued with succession of oracles. The ultimate responsibility for the cult lies with the Lundu paramount, who is to provide Mbona with a “wife.” This elderly woman, called Salima, lives in Khulubvi and communicates Mbona’s wishes received through dreams and possession. An outside medium may also perform this function, and local chiefs have subsidiary shrines. The spirits communicates via this medium and their lineages spans generations and there is a system of succession.
The Khulubvi and Associated Mbona Sacred Rain Shrines are a world heritage site (UNESCO).
