अथर्ववेद:, (Atharvavéda)

The Artharva-Veda is the "Knowledge of the Fire Priests [atharvans]". An atharvan was a priest who worshipped fire and Soma.[19]
The Atharva-Veda Saṃhitā has 760 hymns, and about one-sixth of the hymns are in common with the Rig-Veda.[20] Most of the verses are metrical, but some are in prose.[21]
It was compiled around 900 BCE, although some of its material may go back to the time of the Rig Veda,[22] and some parts of the Atharva-Veda are older than the Rig-Veda.[23]
The Atharvana-Veda is preserved in two editions, the Paippalāda and Śaunaka.[24] According to Apte it has nine schools (shakhas).[25]
Unlike the other three Vedas, the Atharvana-Veda has less connection with sacrifice.[26] It consists chiefly of spells and incantations, concerned with protection against demons and disaster, spells for the healing of diseases, for long life, etc.
