when your happiness is gone look to the heart within you for the strength to carry on.‎ In your heart you will find special virtues such as faith and hope and love.‎ These gifts have been sent down to you from a power up above.‎ It is faith that keeps the soul searching for the joy the heart hopes for.‎ It is love that heals the spirit making it stronger than before.‎ And if your heart be broken if
