There are many symbols and images that can be used to describe true balance and harmony such as yoga poses, scales and inukshuk status to name a few. Our earth demonstrates true balance on the beginning of spring known as the equinox. The equinox is an astronomical event in which the equator is aligned with the sun. On the equinox, day and night are of equal duration all over the planet. This event signals the beginning of spring.
Here is a photograph of an inukshuk that I took on a beach near Yarmouth, NS that symbolizes balance.
