Igihe cyo Gusoma:
Impamyabumenyi kure yitwa urumuri, kandi urwego rwa hafi rwitwa urumuri
Itandukaniro ryo hepfo rya Luminasity ryongeraho (Luminosotity yo hanze);
Igabanijwemo umurongo wibirimo kabiri, urumuri rwinshi rwo hejuru, kandi ruzengurutse ukurikije imiterere yikibanza gito
Umucyo wa kabiri wo hejuru, nibindi
