Vastu, also known as Vastu Shastra, is a traditional Indian system of architecture and design that seeks to align buildings and structures with the natural forces of the universe. It is believed that by adhering to Vastu principles, one can create a harmonious living space that promotes health, wealth, and happiness. The importance of Vastu in interior design lies in its ability to create a balance between the natural elements and the built environment. According to Vastu, each direction is associated with a particular element and energy. It is important to align the various elements of a building or structure with these energies to create a harmonious living space. One of the key principles of Vastu is the concept of "purushartha," which refers to the four goals of human life: dharma (duty), artha (wealth), kama (pleasure), and moksha (liberation). Vastu seeks to align the design of a space with these goals, ensuring that the space promotes the well-being of its inhabitants.
