Umwuka means spirit or breath in Kinyarwanda (Rwandan language) and Kirundi (Burundian language).
“The word 'spirit' derives from the word 'breath', (spiritus in Latin). Literally breath gives life. Figuratively, the word 'spiritual' connotes whatever is of central and ultimate importance in all aspects of one’s life. It is at the core of one’s physical nature, psychological awareness, social relations, and connectedness to one’s world. It is what gives us life.” ~Mary-Therese B. Dombeck
