Essential dignity is the measure of a planet's relative strength or weakness in its astrological location, both in terms of its degree (in certain situations) and, more.
In truth, there is no superior Sun sign. In the viewpoint of astrology, we are all created equal with our own unique characteristics and benefits.
When a planet is at its exalted position, it exerts its utmost potential and brings out the best manifestations of its inherent characteristics and energy.
The physical and psychological centres of your existence, as well as your ego, fall within Aries' sphere of influence. As Mars is the ruler of activity and resolve, those born under the sign of Aries.
As the Sun's residence is in Leo, it's the second-best time to be born under this sign. When a planet is in its own sign, it is said to be "domiciled."
This is what gives Leo his flair for the dramatic, along with his infectious sense of humour and ability to have a good time.
For the same reason that Aries is the finest of the Fire signs, Scorpio is the third best of the Sun signs.
According to Sharpe, "everyone wants to be a Scorpio" because the sign is ambitious and goal-oriented and because of the mystique and seductiveness it radiates.
