The four quarters of the year and balance

I'm reading the book "The Wren in the Holly Library" by K.A. Linde and someone in it talks about the equinoces being about balance. The moment when summer tilts into winter and vice versa. This is tugging at my mind.

I consider the solstices and equinoces from the solar point of view, not seasonal. To my mind, they are all four of them points of balance. The moments when the sun slips above or below the midpoint at the equinoces or the moment when it turns around from rising or falling at the solstices. They are balance points.

Then there are the cross-quarter days, which I find more emotionally satisfying. Most people consider the seasons to change at the solstices and equinoces, I know. The calendar certainly does. But to me, it makes more sense to count the season's change from the cross-quarter days. Samhain, or Halloween - halfway between autumnal equinox and winter solstice; Imbolc, or Groundhog's day - halfway between winter solstice and spring equinox; Beltane (aka May Day) now celebrated as Mother's Day ... halfway between spring equinox and summer solstice.

And Lughnasa, just past, the lost cross-quarter day. The start of the Harvest season.

There's no real purpose to this post. Just expressing thoughts based on my reading material.
