Atharva veda, kanda 7, suktam 43
Shivasta eka .......
The meaning of the suktam is - Some are praises and some abuses, the wise one does not discriminate and accepts both equally. Only one quarter of the speech is passed on and three quarters remain with the speaker.
Speech has four components - para, pashyanti, madhyama and vaikhari. Para originates from muladhara and develops through pashyanti and madhyama stages into vaikahari, the spoken and heard speech. When a person abuses, only one quarter that is the vaikhari is passed on to the victim. Three quarters remain within the abuser himself. The abuser is harmed three times more than the victim. Feel sorry for the abuser.
