Strikes me as meaning that forgetting Naam is the Sikh equivalent of those four cardinal sins. So in Sikhi forgetting Naam is THE "cardinal sin".

Bro this is listing out the cardinal sins according to brahmin mat  for which the person would be punished with a leper's birth biggest sin however  for a gurmukh is to forget Akal Purakh's presence , Naam .
