We celebrate Easter in the southern hemisphere at the same time as the northern hemisphere, simply because of generational habit, not seasonal appropriateness. The word Easter comes from the name of the ancient anglo-saxon spring Goddess Eostra or Eostara. And the Easter bunny and Easter eggs are all symbols of the fertility that is celebrated at the Spring Equinox. Eggs are a symbol of new life.
To honour and celebrate this time you could gather with some like-minded folk, or with your children and conduct a ceremony to give thanks for new ways, new opportunities and balance in your lives.
Here's a suggestion for a simple ceremony to honour the Spring Equinox with your family and friends.
Paint an egg, perhaps simply decoratively or perhaps with symbols to give particular meanings, to represent something new starting in your life, or something you would like to start. Make a 'nest', place it in the centre of your circle that you create together to do your ceremony. Do what you do to make sacred space, call for protection, guidance and support and focus together. Go around the circle and have each person explain what their egg represents for them, what their dreams and intentions for new growth this season are and then place the egg in the nest. Once all the eggs are in the nest have everyone focus on them and send their loving supportive energy. This can be done by visualising pink light flowing from your heart area. Conclude your ceremony going around the circle again with each person making a wish for their community and one for the planet.
