Let’s look at important things here –
Moon - Moon represents Mind, Emotions, Mother, Local Government, Peace of Mind, Home Environment, Water, Milk etc.
Swati - Swati is nakshatra of independence, Justice, Fair-Play and Business People. For more information on Swati Nakshatra, please check this link - https://www.astrosaxena.com/swanaksh.
Libra - As Swati is a part of Libra, Libra sign and its representations also become important. Libra is the 7th sign of Zodiac Belt, hence it represents the energy and things related with 7th house of horoscope, i.e. Market Place, Business, Partnerships, Relations etc. Libra is sign of Balance, i.e. striking the Balance between 2 parties/ideologies or even at personal level between our own dilemmas. It is sign of Peace and Diplomacy. And this is what we are seriously looking for after the conflicts and disagreements of Virgo, i.e. Peace to prevail. At personal level, Libra is seen as sign of Relationships. Libra is consisted of 2 and half Nakshatra named Chitra, Swati and Vishakha. Libra's lord is Venus only.
Rahu - As Rahu rules Swati, Rahu's position and dignity is important to know about the overall functioning of any planet in Swati.
Venus - As Venus rules Libra, Venus position and dignity is important to know about the overall functioning of any planet in Swati.
Houses Involved – Also, we can’t afford to forget the houses involved as a planet can be ruling different houses and sitting in different house for every person as per ascendant and planet’s position. To know overall affect, we have to consider the houses involved as those areas of life are being impacted.
Interpretation of Moon in Swati Nakshatra – As Moon represents Mind and Swati is all about being independent, it shows a person who likes to be independent. They can't be controlled by others. Although Moon is still in Libra, a sign of relationship, and mind desires relationship but they won't compromise on their own independence for that relationship. They can't be in such a relationship where partner is trying to dominate or control them. They can be termed as "Free Bird". In business too, they should be working on their own. Partnership with others may not work as partner may try to dominate them. It can also be interpreted as a mind which is very liberal and independent in thoughts. It is interesting that Libra and Liberal has the same root. People may think that these people have ideas which are way ahead of the times. Among other things, it can also be a very balanced mind as Swati falls in middle of Libra sign, the sign of balance. They can see good & bad side of all the issues and be a good judge of situation. Again, they may take these traits from their Mother. Being an independent business person is best career advice for them.
Role of Rahu – Rahu placement is important to guide Moon in right direction, being Swati's lord.
Role of Venus - Likewise, Venus placement is important to guide Moon in right direction, being Libra lord.
Other Factors – And of course, we need to consider conjunction, aspects, house lordship, house position and dashas etc to know the exact results of Moon in Swati. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Moon in Swati can work in a chart.
