Jai Sri Ganesha,
Evil spirits, goblins, ghosts, and jinn are not mere imaginary entities in the mind of the man,
Any being on the sphere of species may experience their afflictions with cause and occasion,
They may unrest the peace at its first and rest may follow that unpredictable,
That could be the reason devotees pray suitable in honor of Bhagwan Shani dev to safeguard themselves,
May Lord bless all,
Thanks, please
