Whatever you can get away with.
Kigango (plural: vigango) is a carved wooden memorial statue erected by the Mijikenda peoples of the southeastern Kenya coast.
Many first world people might view the Kigango as an example of a backward superstition. And while superstition/deeply felt cultural beliefs might be considered an impediment to modern civilization (supply your own air quotes, please) they are also an integral part of a culture that may be lost through the increasing homogenization of 21st century society. "Lagos" juxtaposes the modern skyscraper with the traditional Kigango where the chip carvings might as easily be windows.
And yes, I am aware of astrology, numerology, Scientology, and others too numerous to mention.
