It was mentioned in Ani issue of Sudarsanam, that there is a remedial slokas for ancestral afflictions (Pitru dosham) and afflictions caused by serpents (Naga dosham). Is there any Desika sloka to mitigate the evil eye of relatives. Moreover, for generations we are affected by sarpa dosham (affliction due to serpents), how to safeguard our children from being affected from the afflictions? Shall we recite GarudaDandakam and GarudaPancashath or should the children recite them?

Both children and elders can recite GarudaDandakam or GarudaPanacashath to mitigate Naga dosham. Reciting GarudaDandakam on Garuda Panchami will remove the affliction. Prappanas need not be worried about any calamities for Emperuman always protects us. Any type of Naga dosham will be removed when the servitors of Emperuman recites Garuda stotrams.
For safeguarding from jealousy and other evil eyes, recitation of GarudaPancashath would be beneficial as the palasruthi sloka states it destroys mental instability which is the cause of jealousy and other bad motives.
It is clearly mentioned in palasruthi of GarudaPancashath “vyaadhidaiva aadhipIDaa”. In this Aadhi means unhinge, which induces jealous and negative thoughts in us. To eradicate such evil eyes it is best to recite GarudaPancashath.
