Upavedas (उपवेदाः)

There are four Upa-Vedas or subsidiary Vedas, viz., the Ayurveda, the Dhanurveda, the Gandharva Veda and the Sthapatya Veda forming auxiliaries to the four Vedas.

Some scholers consider Artha Shastra as the fourth Upaveda instead of Sthapatya Veda.

The Upavedas supplement the Vedas with more specific applications of Vedic teachings into the cultural field.

Sthapatya Veda, more commonly called Vastu, shows the right design of structures to bring in wholesome earth and spatial energies. This is essential for the proper orientation and construction of clinics, hospitals, and healing rooms. Some people may suffer from disease mainly due to the fact that the wrong construction of their houses exposes them to harmful directional forces. For this reason, many ayurvedic doctors will question patients on how their house is situated as part of their diagnosis. Yoga uses Vastu for the orientation of temples, ashrams and meditation rooms.
