It is not only my favourite season, but, I believe, also my power season. I'm not sure why that is. I wasn't born in March. I was actually born two months early, actually prematurely, so I'm curious about that.
Spring equinox occurs when night and day are about equal in length, when planet Earth is not on an axis; see http://en.wikipedia.org/wiki/Equinox for a picture of the earth.
To me, Spring is a time of renewal, rebirth, and growth. How exciting! To me, it's also about potential, potentiality, possibilities, and (being) limitlessness...the latter spiritually speaking of course!
What does the season of Spring mean to you and how are you in Springtime?
