Let’s look at important things here –
Moon - Moon represents Mind, Emotions, Mother, Local Government, Peace of Mind, Home Environment, Water, Milk etc.
Rohini - It is nakshatra of growing, moving forward and being ambitious. It is a nakshatra of business people. Due to mythological story involved, it is also nakshatra connected with sexuality. For more information on Rohini Nakshatra - https://www.astrosaxena.com/rohnaksh .
Taurus - As Rohini is part of Taurus, Taurus sign and its representations become important here. Taurus is the 2nd sign of zodiac belt, so it represents many things related with 2nd house of horoscope like, Hoarded Wealth, Assets, Savings, Finances, Luxuries and Liquid Money. All in all a sign related with luxuries and all the conveniences of life. Taurus is consisted of 2 and half Nakshatras, i.e. Krittika, Rohini and Mrigshira. Taurus' lord is Venus.
Venus – As Venus rules Taurus, Venus’ position and dignity is important to know about the overall functioning of any planet in Rohini.
Moon - As Rohini is ruled by Moon, Moon's position and dignity will also have an important role in functioning and results of any planet in Rohini.
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 Rohini Nakshatra – Although Moon is exactly exalted at 3 degree Krittika and it is considered in exaltation sign throughout Taurus but it is Rohini nakshatra where Moon is happiest. It is because of mythological story where Rohini was the most beloved wife of Moon and Moon liked to spend his most of time wth Rohini. So, it is common sense that when Moon will be in Rohini nakshatra, Moon will be overjoyed. These people generally keep a very balanced, stable and calm mind. They are calm under all sorts of chaos which is most challenging. Then they are business-minded people as Rohini is nakshatra of business people. They can be in business related with wealth and luxury as Rohini and Taurus both represent that. They are also very sexual by nature due to mythological story involved where Brahma wanted to have an incest relation with his daughter Rohini. As Rohini is nakshatra of creation or creativity, these are very creative minds. Now, in negative sides of Moon in Rohini, they can be very jealous of others especially in love matters as all other sisters of Rohini were jealous of her because Moon used to spend more time with Rohini. Also, they like to hoard on to wealth or assets or cling on to relations as they are afraid of instability and changes in life. It shows that basically they are unsecured minds and their biggest lesson to learn is to accept that instability and changes are part of life and everything is going to change or end one day. Needless to say that it shows lifelong support from Mother.
Role of Venus – Venus's position will become important in functioning and results of Moon in Rohini as Venus rules Taurus.
Role of Moon - As we are discussing about Moon's position only, we need not to separately see for Moon's position.
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 Rohini. 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 Rohini can work in a chart.
