The five pointed star has been considered protective in many cultures for thousands of years. The circle is a protective form. All of these features were employed in the Colonial Flag because the colonists feared violent attack from Indians, pirates, Spain, etc. Secondly, they feared witchcraft, otherwise known as mental palpractice i.e. using the mind to harm others, or just the effect of non deliberate but angry thoughts. These problems are still common today.
Thoughts are things.
It is a scientific fact that thoughts affect us and those around us. The Double Star Resonator is one 5 pointed star placed upon another. This design occurs both as single stars and as double stars in nature over and over again. Many flowers and trees have arrangements of five petals. In nature, a five pointed star flower reduces environmental radiations.
