This leaflet will help when trying to visualize colors. In chapters 33 and 34 of Merging with Siva, Gurudeva tells us that it is possible to develop the ability to see thought forms and emotions around people. This is the human aura. This leaflet explains what the different colors represent, such as when someone is "green with envy". These colors were specifically chosen by Gurudeva as the main spectrum of seeable astral colors.
The leaflet measures 8"x5" and is front and back.
