Each direction is associated with specific elements and energies, and by aligning a building in accordance with these principles, one can optimize the flow of positive energy and create a more harmonious living environment. For example, the north direction is associated with water elements and is considered auspicious for placement of the main entrance, while the south direction is associated with fire elements and is best avoided for main entrances.

Another important aspect of Vastu planning is the use of symbolism and sacred geometry in design. In Vastu Shastra, certain shapes, symbols, and patterns are believed to hold spiritual significance and can influence the energy flow within a space. By incorporating these elements into the design of a building, one can enhance the overall energy and create a sense of balance and harmony. For example, the use of mandalas or yantras in architectural design is believed to promote positive energy and create a sense of tranquility and peace within the space.

Vastu planning also emphasizes the use of natural materials and sustainable practices in construction. According to Vastu Shastra, the materials used in a building can have a significant impact on the energy flow within the space. By using natural materials such as wood, stone, and clay, one can create a more harmonious living environment that is in tune with the natural world. Additionally, Vastu also promotes sustainable practices such as rainwater harvesting, solar energy, and organic gardening, which not only benefit the environment but also contribute to a healthier and more balanced way of living.
