"Someone declares that "in the New Era a mother must love another's child as much as her own." This statement is much too strong, and therefore not convincing. It is impossible to demand superhuman feelings from an earthly mother. Let us leave her with her natural right to love her own child more. But we may add that a true mother will find room in her heart also for another's child. All children should be dear to her all-embracing heart. The excluding love is terrible, but the containing love will have its gradations."
