When the Sun warms water, water evaporates and rises towards the Sun. There it gathers new light; it is renewed. The molecules of water receive an update of the Divine Plan. Light comes anew from the Source of All through the consciousness of the Sun to be given to the Earth as rain or snow.
When light is refracted through raindrops to create a rainbow, you can see the light of oneness revealed in the colours of the spectrum; the one becomes many. You might take this as a reminder of your own beauty: that through you your Divine Self creates wonders.
Let your thoughts receive renewal as the rain does. Allow your mental energy to be lifted into the light so that it is refreshed and can precipitate into the thoughts that most accurately reflect the beauty of your Divine Self.
