Vastu Shastra emphasizes the significance of the main entrance in channeling energy into a home. The most auspicious directions for a main door are North, East, and North-East, as they invite prosperity and positive energy. Conversely, entrances facing South-West, South, or West may attract negative influences. To enhance positivity, ensure the main door is well-maintained, opens clockwise, and is adorned with auspicious symbols. Implementing these Vastu principles can foster harmony and well-being within the household.
