Ved is the scripture of our Sanatan Dharm we can say it is one of the most important Vedic literature. There are four Ved: Rig Ved, sam Ved, Yayur Ved, and Atharv Ved. Rig Ved is the oldest one and Atharv Ved is the newest. So, these Ved actually represent the collection of oneness, like Sam Ved, are the collection of music and lyrics, hymns and all, and in the case of Atharv Ved, it is the collection of magical formula for creation, health-related solution for the environment and living organisms.
