This quotation can be viewed in the context of a book
"Search for the seed of good in every adversity. Master that principle and you will own a precious shield that will guard you well through all the darkest valleys you must traverse. Stars may be seen from the bottom of a deep well, when they cannot be discerned from the mountaintop. So will you learn things in adversity that you would never have discovered without trouble. There is always a seed of good. Find it and prosper."
"That which causes us trials shall yield us triumph: and that which make our hearts ache shall fill us with gladness. The only true happiness is to learn, to advance, and to improve: which could not happen unless we had commence with error, ignorance, and imperfection. We must pass through the darkness, to reach the light."
