Explanation:

Section 320 of the Indian Penal Code lists eight kinds of hurt which are designated as 'grievous'. The first one listed is 'Emasculation'. Hurting religious sentiment is an offence under Section 295A, but not grievous hurt. Hitting someone with a hockey stick could cause grievous hurt depending on the injury, but 'Emasculation' is explicitly listed as a type of grievous hurt itself.
