Proverb pointing out that prominent people sometimes fail to help their immediate family or hometown.
A lamp does not illuminate its own base / experts often overlook home needs
taa haimuliki base
"Mtaalamu huyo amesaidia wengi lakini kaka yake yuko maskini; kweli taa haimuliki chini yake."
Translation: That expert helped many yet his brother is poor; truly a lamp does not illuminate its own base.
