Sun rules 12th house is in 7th house in Pisces

Sun in the 7th house in Pisces sign gives the person a very spiritual approach towards relationships and partnerships. As Pisces is a watery sign, it brings a lot of emotions and sensitivity to the person's nature.

This placement of the Sun indicates that the person may face difficulties in maintaining personal relationships as they may struggle with their ego and pride. They may find it challenging to balance their personal and professional lives.

On the positive side, this placement can give the person a very creative and artistic inclination. They could also have a strong desire to help others, especially those in need.

As an astrologer, I would suggest that the person should work on balancing their ego and being more flexible in their relationships. Meditation and spiritual practices could also help them overcome any imbalances and bring clarity to their thoughts and actions.
