The Sun is the Leo's planetary ruler, but because you were born in the third Decan, or part, of the sign, you are also subject to the planetary influence of Mars. The Sun's power manifests in your creative and individualistic nature, but the Mars' power is reflected in your highly assertive and active qualities. The Sun and Mars pair to make you for more ambitious than other Leo Decans. You have the tools to creatively accomplish your goals. Your greatest challenge may be the dark qualities of your planetary influence, which includes the aggression, violence and restlessness of Mars. Stay positive and optimistic in your dealings, and you will continue to propel yourself on a successful path.
