Jai sri Ganesha,
Muttering the name that Naam Jaap could be a help to pause the mind from wandering in gross reality of world,
But never tax the mind to do it, let it be in viable reality to yield favorably,
As long as spirit in body, fear and diseases are but natural, try to overcome the fear with feeling of reality that almighty God is ever along with, and will take care of hazard things suitably,
Idle thoughts could be deadliest trait for fear, try to engage self in truth with nature of self and the corresponding reality,
Jai Mahadev
