The full moon and the 21st March, marked the Spring Equinox - when day and night attain equal length.

It’s hard not to notice new life emerging from buds and feel the welcome relief of warmth in the sunshine.
The breaking of shells and resurgence of growth are the natural events celebrated at this time - think Easter eggs for example. Nature’s explosive force is happening on every scale from tiny seeds to the terrible earthquake in Japan.
