1. Five Elements (Pancha Mahabhutas):

Vastu is based on the idea that everything in the universe is composed of five basic elements: Earth (Prithvi), Water (Jal), Fire (Agni), Air (Vayu), Space (Akasha)

2. Directions and Energy Flow:

Vastu emphasizes the importance of cardinal directions (North, South, East, West) and their association with specific energies. Each direction is linked to different elements, gods, and aspects of life: Vedic Astrology also considers 9 planets (Grahas), which influence various aspects of life. These include: North, South, East, West

3. Balance and Symmetry:

Vastu advocates balance and symmetry in the design of a space. It encourages a central, open area known as the Brahmasthan, which should be clear and unobstructed. This area is believed to be the energy hub of a building, and its openness ensures positive energy circulation.

4. Building Structure::

• Entrances and Doors: The positioning of entrances and doors is crucial for proper energy flow. The main entrance should be in an auspicious direction, ideally in the North or East.
• Windows and Ventilation: Proper ventilation is important for maintaining air flow and keeping the environment fresh. The design of windows should consider directions to avoid blocking positive energy.
• Rooms and Layouts: Vastu suggests specific placements for rooms such as bedrooms, kitchens, bathrooms, and living areas, each of which corresponds to different energies and functions. For example, the kitchen should ideally be in the southeast, as this direction is associated with the fire element.

5. Colors and Materials:

The choice of colors and materials for the walls, floors, and furnishings also plays a significant role in Vastu. Colors such as white, light yellow, and pastels are considered to promote calm and positive energy. While building materials should ideally be natural and free from harmful chemicals or imbalances.
