These are global Transit energies that must be carefully nuanced according to your personal birth chart; see articles on the Sun in transit for reference.
For an interpretation of the Sun in your own birth chart, see the Zodiac Signs.
The Sun is one of the attributes of the Animus in the chart, and as such, it can indicate a Projection of these masculine energies.
It also often provides information about the father, or the native’s husband, or the leader, manifesting qualities colored by the sign it occupies.
Individual and Relational Crisis
When the Sun transits the 8th House, this marks a period of metamorphosis, crisis, and deep transformation.
The personality feels a more urgent need to evolve, to break with the status quo, and to reassess all the elements that arise from shared dynamics within relationships, particularly with the romantic partner.
This can express itself on a material level through the management of resources, money, assets, or a budget, sometimes with unusual income coming in, or conversely losses if the Sun is afflicted.
It may also manifest physically through sexuality, or allow for the sublimation of these themes into a higher level of interpretation and understanding.
As the Sun symbolizes vitality, individuality, and our fundamental realization, it is here placed in a sector of rebirth, regeneration, but also death.
This is most often understood symbolically, fortunately.
Even if there can be an underlying sense of anxiety during this passage, it is a necessary phase for spiritual elevation, which will be more directly accessed once the Sun enters the 9th House.
Under this transit, there is often a need for withdrawal, for greater emotional security, for a more intense bond with one’s partner, and for a stronger sense of control.
In some cases, this may also express itself in the opposite way, through a desire to destroy a relationship. Here again, it is the need for control that is being expressed: breaking things in order to prove mastery over them.
More generally, this period often facilitates a sorting process within the intimate sphere, deciding what must be kept and what must be let go.
One may become more secretive, mysterious, or manipulative on a social level, as the Sun takes on a more concealed quality.
There is a drive to go to the core of things, to better understand oneself and others, and to explore the unconscious, with the Sun acting like a magnifying glass that forces awareness.
In projection, the Sun may also express these themes through the father, the spouse, or the employer, who can then become more directly involved in the crises described above.
