you behold the exact complement of yourself. Yourself and herself,
brother and sister, are the links which your parents have left to hold
their minds, their qualities, their aggregated development and
progression, to the earth. All that your parents were, yourself and your
sister will perpetuate, adding the acquirements of your own lives. You
have in your sister an opportunity for self-study without its like or
equal. Where your sister is weak, there are you weak (naturally) also.
Your vanity may conceal the fact in your own nature, but her character
will express it to you.
