Ukungahoyi oko mzuzwana ingxaki yokunika amandla afanelekileyo, kuyenzeka ukujonga ixesha elizayo ukuveza ukuhlela okutsha kwentlobo ntlobo zenqanawa ngokunxulumene nezantya ezinokuzifumana kwinqanawa ezihlonyelweyo ezineziqu ezinye, ezihamba ngaphezu kwamanzi, eninga zingantywiliselwa emanzini, okanye ezintywiliselwe ngokupheleleyo ngaphantsi kwamanzi, iinqanawa ezihlonyelweyo ezineziqu ezibini okanye ngaphezulu ezihamba ngaphezulu kwamanzi, okanye ezinga zingantywiliselwa.
