28.4  Symbol no. 28 symbolises the living beings' eternal life, which, as previously mentioned, is an eternal road leading upwards through an eternally changing experience of light and dark contrasts or the principles of the unpleasant good and the pleasant good. We already know how this journey is organised in the form of spiral cycles and planes of existence; we will therefore here symbolise merely a small part of this road of life, which has neither beginning nor end.
