Naag dosha also known as Sarpa dosha is different from Kaal Sarp Dosha in many ways. The Dosha happens due to rage and extreme anger by the God of Serpent.
Rahu is said to be the head and Ketu as tail of the Sarpa. Rahu shows his unlimited want, hunger and chaos while Ketu shows how to overcome things or Moksha. Rahu gets disturbed when one exploits the environment or nature. Serpents are very powerful energy and the protectors of the natural spirits.
