Let’s look at important things here –
Sun - Sun represents Personality, King, Government, Father, Authority, Career, Top Positions, Ego, Self Esteem, Health, Education etc.
Moola Nakshatra - It is a nakshatra of research, digging deep and knowing the hidden truth of things and people in life. For more information on Moola Nakshatra, please read this - https://www.astrosaxena.com/Moolnaksh .
Sagittarius - As Moola is part of Sagittarius sign, Sagittarius and things represented by Sagittarius are important here. Sagittarius is the 9th sign of Zodiac Belt, hence it represents many things related with the 9th house of horoscope like Religion, Knowledge, Wisdom, Higher Learnings, Gurus, Teachings from your Father etc. Besides it also represents Coaching, Universities, Professors and Preachers, Higher Wisdom, Written Law of the Land etc. Sagittarius has 2 and half nakshatra which are Mula, Purva-Ashadha and Uttara-Ashadha. Sagittarius' lord is Jupiter.
Ketu - As Ketu rules Moola, Ketu's position and dignity is important to know about the overall functioning of any planet in Moola.
Jupiter - As Jupiter rules Sagittarius, their position and dignity is important to know about the overall functioning of any planet in Moola/Sagittarius.
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 Sun in Moola Nakshatra – If Sun is in Moola nakshatra, 1st of all these people can be very much interested in research related activities and they can be in research oriented career. As it is nakshatra of destruction, their career can go through one major phase of destruction and rebuilding. Same with their overall life/personality as they can go through a major transformation there too. They can be seen as having a very intense personality. They can be under illusion about themselves or their path for major part of life as Moola is ruled by Ketu and Ketu eclipses Sun. It would need digging deep within self to find out what they really are and what they want to do in life. Occult or any other research oriented career remains the most commonly seen career for them. As Moola is part of Sagittarius, these people can be interested in educational research or research related to archaeological or historical site. Likewise, things related with the house which Sun rules in the chart can go through a phase of destruction and rebuilding. If Sun is your relationship oriented planet then same applies in relationships too.
Role of Ketu – Ketu placement is important to guide Sun in right direction, being Moola's lord.
Role of Jupiter - Also, Jupiter placement is important to guide Sun in right direction, being Sagittarius 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 Sun in Moola. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Sun in Moola can work in a chart.
Hope this helps. Please post any comment or query you may have.
