Developments in Medicine:
During the early Vedic period, healing was thought to be the duty of the priests. Diseases were seen as the results of God's wrath for sins committed, or of being possessed by demons. Interwoven with these ideas, we find speculations about the origin of disease, use of healing drugs, beneficial treatment and surgery in the Vedic texts. The Ayurvedic concept of 'medical knowledge as a science' developed only later.
