Part of Fortune
From Astrowiki-en
Synonym: Pars Fortunae (latin)
The most widely used sensitive point in the horoscope. Its symbol is a cross within a circle (Symbolism). There are two different ways of calculating the part of fortune or Pars Fortunae. For day-time births, the Sun's degree is subtracted from the sum of the Moon's degree and the Ascendant. For night-time births, the Moon's degree is subtracted from the sum of the Sun and the Ascendant. More details can be found under the heading "sensitive point".
The part of fortune symbolises the harmonious relationship between the conscious aims (Sun) and subjective feelings (Moon) and their realisation in the present moment (Ascendant).
