A son who cares deeply for his mother can speak of not forgetting the on he has received from his mother and mean that he has for her Hachi’s single-minded devotion to his master. The term, however, refers specifically not to his love, but to all that his mother did for him as a baby, her sacrifices when he was a boy, all that she has done to further his interests as a man, all that he owes her from the mere fact that she exists. It implies a return upon this indebtedness and therefore it means love.
