Universal principals state that life is characterised by cycles, flows and rhythms, just as nature does with its seasons.
Not only nature but OUR lives are also defined in cycles: time to create, time to preserve, time to let go/destroy and time to refresh/renew.
A chart will be worked out of your yearly 7-life cycles based on your birthdate. This can become a very good reference tool to better understand the ebb and flow of your year. It remains the same each year.
