Mahabharat Reference

The Mahabharata does describe incredible architectural and technological feats that could be considered advanced for their time. The palace of Indraprastha, for example, was a marvel of illusion and craftsmanship, designed by the divine architect Maya. It had features that could confuse and disorient visitors, with floors that looked like water and vice versa. This demonstrates a sophisticated understanding of engineering, optics, and psychology to create an immersive and interactive environment. 

Another example is the use of divine and magical items, such as the various weapons and chariots that possessed unique powers and seemed to respond to the wielder's thoughts. While not a "smart home," this points to a concept of technology that is responsive, personalized, and seemingly intelligent. 

In essence, while the Mahabharata does showcase a vision of advanced and interactive technology that responds to human needs and intentions, albeit through divine or magical means rather than electronics and software.
