Final one for Mercury through Nakshatras.
Let’s look at important things here –
Mercury - Mercury represents communication skills, marketing, calculative ability, younger siblings, hobbies, skills with hands, intelligence, quick decision making, logical thinking, youthfulness etc.
Revati Nakshatra - It is final nakshatra, hence it represents closing of things. It is nakshatra of liberation and soul's final destination. It is also nakshatra of creativity and imagination. It also represents wealth as Revati actually means Wealth. Please check this link for more info on Revati Nakshatra - https://www.astrosaxena.com/revanaksh .
Pisces - As Revati 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.
Mercury - As Mercury rules Revati Nakshatra, its position and dignity is important to know about the overall functioning of any planet in Revati.
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 Mercury in Revati Nakshatra – Mercury is in own nakshatra here but in its debilitation sign. But as I said, Mercury debilitation is something I am least concerned about. It can give health issues related with skin, speech or nervous system or relationship issues but in Career matters, it may not be that harmful. Mercury in Pisces/Revati can make someone highly imaginative and creative. They are mostly seen as creative writers. As it is the nakshatra of deepest level of creativity and spirituality, their business can be related to these matters. As Revati literally means wealth, they can be in business related with wealth or finance too. But being an author remains the biggest possibility with this position of Mercury.
In relationship matters, Mercury's debilitation will create troubles. Also, it can make a person too imaginative in his approach and he can live in his own dream world.
Role of Mercury - As we are trying to interpret Mercury only, we need not to see Mercury's position separately.
Role of Jupiter - Likewise, Jupiter placement is important to guide Mercury 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 Mercury in Revati. So, we always need to take a holistic view of chart rather than just 1 planetary position.
Conclusion – So, this is how I see Mercury in Revati can work in a chart.
