Introversion, Re-centering on One’s Foundations
When the Sun transits the 4th House, the period tends to be more introverted, marked by a need to withdraw into oneself and reconnect with one’s roots, origins, family, and home.
There may be changes in these areas: a move, renovation work, or a new interior design project, for example, the arrival of a new person in the household or discoveries related to one’s parents, ancestry, or traditions.
The protective instinct toward loved ones is heightened. There is pride in one’s family and where one comes from, yet this sky can also make one far more sensitive, with fears of being ignored or abandoned.
There is a strong need for reassurance and emotional security, for confirmation of the feelings others have toward you, and for a sense of shared belonging, within a couple, for instance, so that the family unit is strengthened and the clan more tightly knit.
Often, this is a time for introspection, assessment, and questioning, for delving into elements of the past.
Depending on the Sun’s aspects, this can translate into family conflicts, inheritance issues, or matters concerning the family home, as well as nostalgia, melancholy, or even Depression.
Yet when handled constructively, this period can ultimately provide healthier foundations and inner strength.
You know that you have a safe space to retreat to after life’s ups and downs, that part of your family life does (or can) form the solid ground on which everything else may be built and allowed to thrive.
That is what this phase is working toward.
Within your personal zodiac formed by the Houses, this corresponds to the first phase of tension, associated with the waxing square, which challenges the creative seed born when the Sun was transiting the 1st House.
At this stage, inertia must be overcome in order to move toward expansion and fulfillment.
