In 1904, J.M. Barrie gave us Tinkerbell. He was from Scotland. There's something about Scotland and Ireland. Isn't there? The "wee people" etc.
Fairies and elementals aren't everywhere. In fact, they may not be where you think they ought to be. The density of humanity, psychic forces or pollution could force them to leave an area. If they do inhabit an area, it's important to be open to the idea of these special little beings. When you are, you are more apt to see them.
"And so the shadow, being the opposite of light, was always considered by the peoples of the East to be a concept of darkness and therefore hostile. Hence came the idea that absolute spirituality has no shadow. Among many tribes of Asia there exists a belief that the Devas do not cast a shadow, therefore, a holy man should not have one either. The foundation of this belief should be sought in the teaching that deals with the first ethereal races of humanity and the subtle spheres, since the high substance of the Subtle World, being itself a source of light, cannot cast a shadow." Letters of Helena Roerich II, 23 October 1937
