What does Moon conjunct the Sun mean in Natal Astrology? - Across the Horizon 18

Cazimi is an astrological term which means in the heart. It describes when a planet is tightly conjunct the sun and is described as a very strong positive indicator. In Ptolemy's Centiloquium the moon in cazimi with a benefic planet such as Venus or Jupiter in the ascendant is said to mean that all good things will happen to a native. What does this teach us about cazimi in general?

In this Episode of Across the Horizon, Christopher Warnock and Michael Beeson Discuss the 18th Aphorism of the Centiloquium:

"If, while a benefic may ascend, both the luminaries should be in the same minute, the native will be equally and highly prosperous in all things which can befall him. So, likewise, if the luminaries be mutually opposed by the east and west. But the contrary effect will be produced, should a malefic be on the ascendant." "Ptolemy's" Liber Fructus (translation: Ashmand)
