Pisces - As Uttara Bhadrapada is a part of Pisces sign, Pisces and things represented by Pisces are also important here. As Pisces is the 12th sign of zodiac belt, it represents the same energy and things which are represented by 12th house such as Isolated Places, Spirituality, Imagination, Other Dimension or Other World etc. Besides these things, it also represents your Hidden Talents, Ability to work in background, Spiritual Self etc. Pisces is consisted of last 2 and half nakshatra, i.e. Purva-Bhadrapada, Uttara-Bhadrapada & Revati. Pisces' lord is Jupiter.
Saturn - As Saturn rules Uttara Bhadrapada Nakshatra, its position and dignity is important to know about the overall functioning of any planet in Uttara Bhadrapada.
Jupiter - As Jupiter rules Pisces, its position and dignity is important to know about the overall functioning of any planet in Pisces.
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 Uttara Bhadrapada Nakshatra – When Moon is in Uttara Bhadrapada Nakshatra, which is nakshatra of mysticism and spiritual powers, here mind of person becomes naturally inclined towards spirituality and mysticism. We can understand them as seeker rather than believer. They will be inclined towards spiritual pursuits like meditation etc and seeking the truth. They can be equally interested in different type of mystical subjects like Astrology, Tantra, Black Magic etc. It is clear that mind is working in a different realm here and they are not inclined towards general mundane things of life. They can be interested in knowing about enlightenment or liberation. This is when Moon is working in its purest form but if soul is not an evolved one, their spiritual interests can be there to just show-off and person can easily be a con-man too. Again, mother or home environment can be a reason behind this spiritual inclination.
Role of Saturn - Also, Saturn's placement is important to guide Moon in right direction, being Uttara Bhadrapada lord.
Role of Jupiter - Likewise, Jupiter placement is important to guide Moon in right direction, being Pisces 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 Uttara Bhadrapada. 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 Uttara Bhadrapada can work in a chart.
