Book excerpt: Vastu Shastra is not merely an art but a definite science in itself. This book has made an excellent effort to establish this fact. The book attempts to highlight the principles of Vastu science and its application in designing of the built environment to enhance the quality of life. This science is still relevant and effective in the modern life-changing styles of Architecture with the universal application of its principles. The author has tried to justify that Vastu principles are much in need in the 21st century in view of rapid advancements man is making in other fields without compensating on ecology front, which forms the basis of Vastu. In the end, an attempt has been made to give a compound solution to the problem of Vastu-based planning.
