The timing of a Spiritual Great Age is inspired ' by the heavens '.  Approximately every 2000 years, the Sun moves into a new constellation along the ecliptic ( as measured each year on Northern Spring Equinox day ).  According to Aquarian Spirituality, the Sun is now in the true constellation of Aquarius ( since 2020 AD ).

Each new Spiritual Great Age, is an opportunity to reinvigorate our spirituality, ensuring it is relevant for the times.

Each new Great Age is a time of transformation.
