Affliction to Lagna by Ketu gives fear from spirits, thief’s and dogs. This Shlok means whatever affliction to lagna happens in anyway to counter it, we need to do appropriate remedial measures for them, such as for Ketu we need to learn more about dogs, spirits and always wear some sort of kavach to mitigate such evils.

This is where yantras come in handy, Always wear yantras to protect yourself, I removed a yantra for about three days after about 7 years and i could feel, the energy is missing, Yantra is a place where god resides, So wear them carefully.
