Sun rules 11th house is in 9th house in Gemini
As a Jyotish astrologer, I can tell you that the placement of the Sun in the 9th house in the Gemini sign is a very auspicious placement as it is a Dharma (righteousness) house and the Sun is a natural significator of dharma.
This placement suggests that you have a strong and positive outlook towards life and a deep interest in religion, spirituality, and higher knowledge. You possess great wisdom and are inclined towards philanthropy and charity. You could be a teacher or preacher, as you have the ability to inspire and motivate others with your knowledge and wisdom.
You have a natural curiosity and are always eager to learn new things. You are likely to travel to distant places in order to broaden your understanding and knowledge of different cultures and ways of life. You are also likely to have a strong interest in philosophy and may be drawn towards spiritual practices like meditation and yoga.
However, this placement of the Sun may also make you stubborn and dogmatic at times. You may also tend to be egoistic and may have a tendency to show off your knowledge and wisdom, which could create problems in your relationships with others.
Overall, this placement of the Sun in the 9th house in the Gemini sign is a very positive one, and it suggests that you have the potential to achieve great success in life through your knowledge and wisdom.
