Treasure

Here's another look at the magic word treasure:

Treasure! Next to gold, this is probably the single most magical word in the English language. The very mention of the word stirs the adventuresome spirit in most of us. But why are we so fascinated with tales of lost, sunken or buried treasure? Why, like little children, are we so captivated by the tenuous hopes of discovering a treasure which, as adults, we know probably does not exist? Is it the adventure? Is it the escapism to a different place and time? Is it the eternal hope that the treasure just might exist, and we might be the lucky one to discover it? The answer is probably a combination of all these factors, plus the fact that treasures are occasionally found and highly publicized.

In Jungian terms, taking possession of the "treasure hard to attain" alludes to experiencing individuation—the archetype of total unity.
