"My strength is as the strength of ten because my heart is pure."
Alfred, Lord Tennyson
I think it is true because your strength in character is based on your heart your heart is what makes you. If you are not pure in your heart you are weak in strength of character. If your heart is pure you are stronger than someone who's heart is not pure. If you decide to choose the right your heart is pure and you are strong in character. If you choose the wrong you are weak in character.
