–Sisifo esibiisifo
1, Sizimpawu
(1) Ngemuva kokutheleleka kweqabunga, kuzoba namachashazi e-moire, imiphetho yokuphuzi, uma ijubane lokuqala lishesha, khona-ke amabala aluhlaza angcolile futhi amaqabunga azobola maduze.
(2) Lapho intamo yendlebe yonakele, iphenduka ibe luhlaza okotshani, bese iba nsundu ngokumpunga, ingakwazi ukuhamba, futhi ikhoba lokusanhlamvu liyakhula, nesisindo sezinhlamvu eziyinkulungwane siyehla.
2. Ungakuvimbela kanjani futhi ukwelapha
