What are the motifs in Mother Teresa, in My Own Words by Mother Teresa?

Giving until it hurt is a common motif in the book. Teresa is a radical altruist, meaning that she believes that the good life consists in total devotion to the good of other persons. In fact, she seems quite certain that any human life which fails to consist in total devotion to the good of others is thereby deeply impoverished and inferior as a whole to a life of total devotion.
