A blue candle's magic soothes & relaxes. It is a spiritual color used to obtain wisdom and harmony. Burning one can provide protection, understanding & patience. It promotes happiness, aids in meditation by connecting to intellect & mind, and treats insomnia.
"All the time the ghosts flit past and through us, hiding in the future. We look in the mirror and see the shades of other faces looking back through the years; we see the shape of memory, standing solid in an empty doorway. By blood and by choice, we make our ghosts; we haunt ourselves." __Diana Gabaldon, Drums of Autumn
