Red horses represent the fire element and the Sun (Surya nadi), so they are placed in the South in an odd number (1, 3, 5, 7 and so on) for fame and recognition.
South, horses facing North or East
White horses represent the Moon and the water element; they are placed in the North-West, always in an even number such as two, because the Chandra swar takes even counts. They sort out financial problems.
North-West, horses facing North or East
Join both hands under the nostrils and breathe out once; the nostril whose air strikes the back of the palms more strongly is the active swar.
Besides measuring how many angul the breath reaches, the active element (tatva) can be recognised from the state of the mind: steadiness, joy, restlessness, anger or indifference.
Curtains should be in two (or four) parts, always an even number because they represent the Chandra swar; they should end 1 to 2 inches above the floor and never carry violent animals or a design of the opposite element.
All doors and windows
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.
