Maharishi Vastu and sustainable building design enjoy a very intimate relationship and a shared central aspiration — to build in harmony with Natural Law. Vedic or Vastu architecture is 100% Natural Law-based architecture. In contrast, sustainable architecture is based on the best minds of our generation incrementally discovering and applying more laws of nature than did the prior generation. The sustainability movement is relatively new, emerging just a few decades ago as a reaction to the unintentional harmful consequences caused by two centuries of industrialization. While the goals of sustainable design and construction are good and its development absolutely necessary, it is still grappling with finding a holistic basis for solving our pressing environmental problems. The development of green building technologies is based on the process of observing what doesn’t work, searching for what could, and experimenting to find the best solutions. This trial-and-error process is tedious and vulnerable to unintentional consequences. Foamed urethane, for example, was enthusiastically embraced in the late 1970’s as a super insulation that could make buildings more energy efficient. But after some time, it was understood that its out-gassing poisoned indoor air. The incremental, experimental basis for green building design is an inefficient way to achieve the full status of being a Natural Law-based architecture. While there is much that is valuable and important in the sustainable architecture movement, it needs an additional approach to help it to fulfil its goal of designing a building in complete harmony with Natural Law. That approach is Maharishi Vedice. This ancient, fully developed system, recently revived to its purity and completeness by Maharishi Mahesh Yogi, is based on a complete connection to Natural Law. The source of Maharishi Vastu resides at the silent level of creation where all the Laws of Nature are absolutely harmonious and completely balanced with each other. From this level, any impulse that arises can have only nourishing influences on the individual and the environment. This gives it a distinct advantage over sustainable design alone. Both systems are extremely supportive of each other. Integrating the 21st century technologies of sustainability and the timeless system of Sthapatya Veda ensures that we will best nourish Planet Earth. As green building design is becoming more main-stream, increasing numbers of Maharishi Vastu homes are being constructed using sustainable technologies, as illustrated in the examples below. Some are even completely off the grid.
