Category - Higher Truth
Violet is the colour of universality, consciousness, and unity across all parts of the self. Connect with the colour violet to bring spontaneous insights. It is the colour of higher truth.
Sayings in this series are on a yellow background, go figure.
Higher truths are at home on the self-help shelf and many are even sensible. I believe that they appear only at times when confusion gives way to something a little more real and so there are fewer of them.
They appear on a Sunday, the day of rest and the sun, hence the yellow.
