How the yearly cycles affect each other.

Your Essence and Personal Year cycles are distinctly separate energies that influence you in different ways. Your Essence reflects your mental, emotional, and spiritual state of mind at a particular time in your life and feels like an internal influence; it's a stage in your personal evolution. Your Personal Year cycle, however, feels more external. 

Your Essence and Personal Year cycles overlap creating a duality which produces its own influence. Most importantly, it tells us how you can get the most out of your mix of Personal Year and Essence cycles by looking at their combined influence.

Personal Year cycles run concurrent with the calendar year and change every year, while Essence cycles run from birthday to birthday and can be anywhere from one to eighteen years, sometimes even longer. Therefore, you can have either two or three Dualities during any 12-month period. Three, if your Essence changes (one before your birthday, one after your birthday, and another when the new year starts). If your Essence doesn't change, you have two Dualities, one for each calendar year.

For the purpose of Dualities, Essence cycles with Master Numbers (11, 22, or 33), or Karmic Debt numbers (13, 14, 16, or 19) are reduced to single digits, as their effect in the context of Dualities is indiscernible.
