Manyu Sukta is found in the Rig Veda. Manyu means anger or temper. The hymn reveres the Supreme God Sriman Narayana in His avatar of Narasimha.
Eliminate enemies from your life. These can be both internal and external. Internal enemies can be emotions like anger, jealousy, sadness, arrogance, desires etc and external can be physical forces that cause major hurdles in your path to progress. This also bestows internal strength and courage and provides ultimate Knowledge and Bliss.
It neutralises the negative emotions thereby easing it and prevents a person from committing sins due to anger. It actually converts negative, unpleasant energies to positive, vivacious ones. Those with uncontrollable anger must chant this suktham
