Hello Isabella, Thank you for questions, I hope youbare well, Vastu has its roots in the Atharva Veda. It is difficult to say the exact date when the Vedas were composed, but we can safely say that this knowledge is around 4,000–5,000 years old. Our ancient sages followed Vastu principles while building homes, temples, large ponds, and wells. Many of these structures still stand today as living proof of this science. Even in the modern world, we see Vastu principles at work. For example, what we now call Geopathic Stress disturbance caused by underground water streams, fault lines, or magnetic imbalance was already understood in Vastu as an imbalance in land energy. If you would like to know more about this, feel free to ask me more questions. I will be happy to explain in detail.
