In the seven sea-salt lump usara of the main door, are the rounds made clockwise or anti-clockwise?
Clockwise only. Standing outside the main door, circle the hand holding the seven lumps clockwise in front of the door for the rounds, then sweep once or twice from the front as if pouring the energy out and throwing it away outside. Do it only while the right nostril (Surya swar) is active; done in the left swar it gives no result and instead invites negativity. Swar vigyan is the base of everything, and without swar, vastu is handicapped.

Mulank 4 and 7 point to a South-West door. If Rahu is exalted in the chart, can one keep a South-West main door?
It has been seen that people whose Rahu is exalted, at a good degree and giving good results, had South-West doors without much trouble. Even so, a South-West door should be avoided. Where one exists, do the main door usara with seven sea-salt lumps given in this class, which gives very good results.
Do the swastiks for nazar and other uses need to be made at a particular time?
Select a muhurta if possible. Otherwise make swastiks for shanti and paushtik (peaceful, nourishing) work in the Chandra swar and for ugra (forceful) work in the Surya swar. Any remedy done in the wrong swar gives no result.
Should the horseshoe for a West entrance be fixed inside or outside the door, and which way should its mouth face?

Should the main door's chaukhat, the dehleez, be slightly higher than floor level?
Yes, it must be higher than the floor; only then can it stop the energy. It should be made of wood in particular.
What does a window do, and why should it open outward?
A door is placed by pada, but a window does not work on the surface current: currents are dense near the ground and lighter higher up, so positive energy stays higher, which makes ventilation a must. Windows and ventilators bring in clean air and push the negativity of the house out, so they should open outward, while the main door opens inward; sliding windows are acceptable. Keep windows in even numbers, two-shuttered if possible, in one row at one level, with a window beside the main door; open all windows in the morning and keep the left (Chandra swar) window open during the day.
What is door power?
When the main door is installed in a muhurta, its four-piece frame (chaukhat) is set up and the base piece of wood is the dehleez (threshold). Door power means installing that dehleez in a muhurta combined with the right swar, with the prescribed samagri, such as silver and pancha ratna, placed in the ground beneath it. Done this way, even a door in a wrong place has about 50 percent of its defect removed. The full door treatment is part of the complete course.
