What Sun in the 6th house means
The Sun represents your essential self, ego, and the energy that drives your life. The 6th house governs your daily habits, job, health, and service to others. With the Sun here, your sense of purpose is often found in the practicalities of life. You may feel most alive when you are organized, productive, and contributing in a tangible way. Your identity can be very tied to your work and the routines you establish for yourself. This placement often points to a strong desire to be useful and effective.
