I have always enjoyed rainbows; it took a physics class for me to realise that they are created by light refracted through water droplets. I remember directing white light at a prism and being amazed at the colour spectrum emitted from the other side.
This fascination sparked my interest in candle magic, auras and chakras. I count myself fortunate to live in a house that has a leaded, coloured glass window in the bathroom. Some of the clear glass panels have bevels that catch the bright northern light (southern hemisphere) and project rainbows onto the white porcelain fittings and tiles. The effect is heartening and magical.
