Nature: pure, nirmal, nirdosh, niramay, niranjan and nirvikar; it needs nobody's order, praise or insult and never changes its time. The first ray of the Sun falling on a planet makes that planet's hora and names the weekday. A house where people wake up late has Surya inactive; rising before sunrise keeps it active. It is a leading power that opens the eyes of knowledge and makes good speakers, kings, ministers and organisers. Body link: heart.
Imbalanced signs: fear, wrong and slow decisions, no time management, heart disease. A fully blocked East keeps it imbalanced however many treatments are done.
Good uses: bathroom (its ideal zone), administration, manager's chamber, locker, planning, meeting and conference rooms, office. Businesses: politics, administration and government work.
