Having the natal Moon in the first house of one’s birth chart can represent an individual who deeply identifies with their emotions. As a result, at their core, they are fueled by desire — as emotions are the product of the callings of the heart, fulfilled or not. For this person to understand the reason for their mood, and its’ swings, attempts should be made to search for the root cause — that is, where the feeling is stemming from. Questions like, ‘what is it that I’m not getting, and that I need, that is causing me to feel like this?’ can help in that search. Because the line between want and need can be so fine, even the most trivial of desires are indicative of a not so trivial, but innate necessity, that has not materialized for them, in their opinion.
