, the goddess of prosperity, came to reside in cow dung. In the legend, Lakshmi asks cows to let her live in their bodies because they are pure and sinless. The cows refuse, describing her as unstable and fickle. Lakshmi begs them to accept her request, saying that others would ridicule her for being rejected by the cows, and agreeing to live in the most despised part of their body. The cows then allow her to live in their dung and urine. Cow dung was used by some Hindus as a means of cure COVID-19 pandemic in India. The Tantric Buddhist ritual manuals ''Jayavatī-nāma-mahāvidyārāja-dhāraṇī'' and ''Mahāvairocanābhisaṃbodhi '' recommend use of cow dung to purify ''mandala'' altars.

Floor and wall coating

This practice has various names, such as "ukusinda" in Xhosa, and "gwaya" in Ruruuli-Lunyala. Similarly, in India, floors are traditionally smeared with cow dung to clean and smoothen them.

(1976), The Australian dung beetle project 1965-1975, ''Australian Meat Research Committee Review'' 30:1-30 Cattle have a natural aversion to feeding around their own dung. This can lead to the formation of taller ungrazed patches of heavily fertilized sward. These habitat patches, termed "islets", can be beneficial for many grassland arthropods, including spiders (Araneae) and bugs (Hemiptera). They have an important function in maintaining biodiversity in heavily utilized pastures.Dittrich, A. D. K. and Helden A. J. 2012.
