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.
In Leo, the Sun radiates from its own home…
When the Sun transits Leo (by analogy with the Sun transiting the 5th House), it is in its own domicile: charismatic, proud, dominant, imposing, generous, and optimistic.
It shines with its full fire, playful, expansive, and extraverted (see Rulerships).
It provides energy and confidence for the affirmation of personality and encouraging one to step forward as a leader, chief, husband, or father, to “win” and impose one’s will within the social sphere.
This is a more colorful and highly theatrical period, marked by strong self-assertion, reflection on major life projects, great achievements, and all forms of creativity. By extension, your children may also be highlighted.
It is the time of year when daylight force reaches its peak, when flowers and fruits come to full maturity.
By analogy, it also represents the flowering of the individual: full expression, fulfillment, happiness, freedom, and the nobility of spirit one may be capable of displaying.
Creativity is heightened, as are your uniqueness and originality. Pleasure and amusement blend with a certain lightness; there is a desire to be in the spotlight, and one feels gratified to be noticed and acknowledged.
Artistic inspiration can be abundant, and luck is often present as well.
In truth, it is precisely what sets you apart that allows you to truly assert yourself. Boldness tends to pay off, and speculation becomes more attractive than usual: one takes risks, and succeeds.
Your attitude toward life becomes more relaxed, spontaneous, open, and receptive to happiness.
This can be a period favorable to love and romantic serenades, to building a sincere emotional bond.
It may also serve as a time for rest and holidays, sports, leisure, and pleasures of all kinds.
On the negative side, the Sun transiting Leo can also foster egocentrism, pride, pretension, vanity, and impulsiveness.
Internal tension on a socio-professional level may be higher than usual, generating strong nervousness that struggles to find an outlet.
The personality may seek power for its own sake, without scruples or genuinely noble purpose, purely for the pleasure of domination.
This can lead to arrogant authoritarianism, excess, extravagance, and the archetype of the “bad theatrical actor” or the “emperor-dictator” ruling over a fictitious “republic”.
You may also become overly dependent on others’ approval, too focused on appearances and form (to the detriment of substance), resulting in behavior that is biased, artificial, and grandiloquent.
In some respects, this transit can encourage a lack of maturity, a “daredevil” tendency to favor play and risk over responsibility and security.
