In the name of the goddess and god who breathe life into us all,
I consecrate and charge this candle as a magickal tool for healing.
I charge you by the powers of the East, South, West, and North;
I charge you by the powers of the Earth, Air, Fire and Water.
I charge you by the powers of the Sun, the Moon, and the Stars:
To heal Buffy of her illness
I call forth light,
in the dark of night,
to heal the blight,
with strength and with might.
Burn the sickness in your flame, burn the sickness that would maim.
Burn the illness by your might, burn the illness in your light.
Heal Buffy of illness and pain, heal Buffy of all that is bane.
Heal Buffy and set her free, with my will, so mote it be!"
Spell adapted from multiple sources, which I combined and personalized.
