What a profile is
A profile is the role, the costume, a person wears through life. It is made of two numbers — the lines of the conscious Sun (Personality) and the unconscious Sun (Design), for example 3/5. The first number you know and recognise in yourself; the second works more deeply and is often more visible to others.
What lines are
Every gate has six lines, and each line is its own level of expression: 1 Investigator, 2 Hermit, 3 Martyr, 4 Opportunist, 5 Heretic, 6 Role Model. Lines 1–3 are more about your own process, 4–6 about relationships with others. There are twelve profiles in all.
