Let’s look at important things here –
Mars - Mars represents our will power, courage, ability to take actions, aggressive nature, anger, our fighting ability, brother, male friends, a boy friend for a girl, a soldier, an athlete and real estate etc.
Anuradha Nakshatra - It is a nakshatra of following heart's desires or being devotional about something or someone. It is also related with mystical side of life. For more information on Anuradha Nakshatra, please read this - https://www.astrosaxena.com/anunaksh .
Scorpio - As Anuradha is a part of Scorpio, Scorpio sign and its representations also become important. Scorpio is the 8th sign of zodiac belt, hence it represents the things and energy related with 8th house of horoscope like Sudden Events, Secrecy, Dark World, Occult Science, Research, Inheritance, Serving Others, Taxes etc. Besides these things sign of Scorpio also represent transformation, means changing the whole nature upside down. This is one sign which is favorite of every Astrologer, because it has maximum secrets, so every astrologer gets maximum scope of researching. This is sign about which no one can tell with precision that what will happen to the planets in it, as it is sign of secrecy itself. Wherever Scorpio falls in your chart, you may have had biggest challenges in making things related with that house more stable. Scorpio is also one of those unique signs which has 2 rulers, i.e. Mars and Ketu. In Western Astrology, Pluto also co-rules Scorpio. All this makes Scorpio a chaotic sign. Scorpio consists of next set of 2 and half nakshatras, i.e. Vishakha, Anuradha and Jyeshtha.
Saturn - As Saturn rules Anuradha, Saturn's position and dignity is important to know about the overall functioning of any planet in Anuradha.
Mars-Ketu - As Mars-Ketu rules Scorpio, their position and dignity is important to know about the overall functioning of any planet in Anuradha/Scorpio.
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 Mars in Anuradha Nakshatra – Now, Mars is our actions & efforts and Anuradha is nakshatra of following your heart's desire (Anu + Radha). So, Mars in Anuradha shows someone who should always follow his heart's desire in matters of putting his actions and efforts. It is very common to see that majority of population want to work in a field of their interests or passion but due to social pressure, they need to follow another path which others follow. This is position which can give push to person for following his desired path. At the same time,as Mars is in Saturn's nakshatra, there can be delay in realizing the desired path or person can be fearful in early life to follow it. At the same time, it will make person work hard towards that desired path. In later life, person will have courage and will-power to follow that desired path.
In recent times, I have come to know another spiritual meaning of the word Radha. Radha is actually opposite of the word Dhara. Dhara means stream or flowing with the stream. Hence, Radha means flowing against the stream or being rebellious. So, this position of Mars in Anuradha not only can make someone courageous to follow his desired path but it can also make someone follow a very rebellious path and go against the socially accepted norms.
Mars-Saturn combination can also make someone good in technology.
Role of Saturn – Saturn placement is important to guide Mars in right direction, being Anuradha's lord.
Role of Mars-Ketu - As Mars will be in own sign, being Scorpio lord, we need not to see Mars position separately.
Other Factors – And of course, we need to consider conjunction, aspects, house lordship, house position and dashas etc to know the exact results of Mars in Anuradha. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Mars in Anuradha Nakshatra can work in a chart.
