1. When the Sun enters Pisces: the opening of Portal 12
Every year, as the Earth travels around the Sun, the Sun's apparent position along the ecliptic enters Pisces and marks the solar passage through this thirty-degree sector of the tropical ecliptic. In our twelve-portal cosmology, this solar ingress opens Portal 12 — a thirty-day season focused on relationships.
As a mutable water sign ruled by Jupiter & Neptune, Pisces invites everyone — regardless of their birth Sun sign — to bring more relationships into their daily routines, relationships and creative work.
Portal 12 (Pisces) reminds us that relationships is not a rare accident — it is a rhythm we can practice every day.
2. The sacred geometry of Pisces: Vesica Piscis and Sandalphon
Each of the twelve zodiac portals is paired with a classical geometric form and a guardian figure from angelic tradition. For Portal 12 (Pisces), the geometric emblem is the Vesica Piscis, and the traditional guardian is Sandalphon.
In contemplative practice, gazing softly at the Vesica Piscis before listening to music gives the eyes a quiet point of symmetry, helping the mind settle before the first note even begins.
