Orientation: Vastu emphasizes the importance of proper orientation and positioning of a building. The placement of rooms, entrances, and windows should be in harmony with the cardinal directions (north, south, east, and west) to ensure the flow of positive energy.

Five Elements: Vastu incorporates the five elements of nature - Earth, Water, Fire, Air, and Space. Each element has specific characteristics and influences different areas of a building. Balancing these elements is believed to promote positive energy.

Structure and Design: The design of a building should follow certain guidelines. For example, the center of the building (Brahmasthan) should be kept open or minimally cluttered to allow for the free flow of energy. The shape, size, and proportions of rooms and furniture also play a role in Vastu.

Entrance and Door Placement: The main entrance of a house or building is considered crucial in Vastu. It should be well-lit, inviting, and positioned in an auspicious direction. The placement of doors and windows within the building is also important for energy flow.

Room Allocation: Vastu suggests specific functions for different rooms based on their location within a building. For example, bedrooms are recommended in the southwest direction for rest and relaxation, while the kitchen is best placed in the southeast for fire-related activities.

Colors and Materials: Vastu recommends using certain colors and materials to enhance positive energy. For instance, light and soothing colors are preferred for bedrooms, while vibrant and warm colors are suitable for living rooms.

Remedies: Vastu Shastra offers remedies to correct any imbalances or negative influences in a building. These remedies may include the use of specific symbols, placement of objects, or performing rituals to purify the energy.
