Libra is a sign of the marketplace where a balance is required to be maintained indicated by the symbol of the Rāśi/ Rashi. Saturn gets exalted here and is in fact exalted here in transit with Rāhu/ Rahu. There is high cerebral initiative in matters of business and enterprise and certain personal matters as well.
The transit Moon is a fructifying agent and its entry into the sign gives confirmation and precipitation to whatever it is that is to transpire. For example, when we speak of the Nodal Kemadruma Yoga, in the radix or the nativity, it is the influence of the Moon on the 2nd or 8th Houses from the Lagna that confirms it.
