Vastu Shastra is an ancient Indian architectural science that focuses on the design and layout of buildings to promote harmony and well-being. It combines elements of art, science, and spirituality, guiding the placement of rooms, doors, and windows to enhance positive energy flow. The principles of Vastu Shastra are based on the five elements of nature: earth, water, fire, air, and space. By aligning structures with these elements, practitioners believe that one can create a balanced environment that supports health, prosperity, and happiness in daily life.
