retrograde Jupiter rules 2nd and 5th house is in 9th house in Cancer
As a Jyotish astrologer, I can infer that retrograde Jupiter in the 9th house of Cancer sign can have both positive and negative effects on an individual's life.
Firstly, the 9th house is considered the house of fortune, wisdom, and spirituality, and Jupiter is the planet of expansion, growth, and knowledge. Therefore, this placement may make the native inclined towards spirituality, religion, philosophy, and higher education. The native may be blessed with good fortune and luck in life.
However, since Jupiter is in a retrograde motion, it may cause delays and obstacles in achieving higher education and spiritual growth. The native may face challenges in realizing their dreams and aspirations in life.
Also, the Cancer sign rules emotions and nurturing qualities. Therefore, the native may possess a compassionate and caring nature towards others. But, the retrograde Jupiter may cause emotional instability and difficulty in expressing their emotions.
In conclusion, the effects of retrograde Jupiter in the 9th house of Cancer sign can only be ascertained after analyzing the overall birth chart.
