Natural light
- Large windows in the north and east bring in morning sunlight, which Vaastu considers most beneficial.
- Keep curtains open during the day in the north and east.
- Use heavier curtains or shades in the south and west to control harsh afternoon heat.
Artificial lighting by direction
- South-east: warm, bright lights to strengthen the fire element.
- North-east: soft, white lighting; avoid heavy chandeliers.
- South-west: warm, yellow lights for a cosy, stable feel.
- Entrance: always well lit, especially in the evening.
Habits
- Replace fused bulbs and flickering tubes immediately.
- Light a lamp or diya at dusk in the pooja room or north-east.
- Avoid very harsh, glaring lights in bedrooms.
Dark corners
A dark, unused corner is a common source of heavy energy. A lamp, plant or bright object can bring it back to life.
