According to Nirukta (11.18) “That by which all sorts of doubts and importections are removed; and expertise is achieved, is atharvaveda.’’. The knowledge, activity and practice lead to the state of perfection in all branches of knowledge, whether social or physical Sciences.

So Atharva Veda deals with Science, technology, applied social Sciences and human behaviour covering Mathematics, Physics, Chemistry, Astrology, Cosmology, Medical Sciences, Agriculture, Engineering, Military, Sciences, Aeronotics and Creation of universe. It also includes Social Sciences as political Sciences, Sociology, Psychology, Economics etc, but not the history of past, kings and queens, and mankind as we find in the present man-made History Books.

5977 Mantras in Atharva Vedas. Atharva veda Mantras are classified in twenty Kandhas with 111 Anuvakas and Seven hundred thirty one Sukthas. But in Practice, a mantra is referred in kandha, suktha and Mantra number.
