Jai Sri Ganesha,
Human is blessed with a perfect faculty to intercept truth and the self, but the majority of people remain bear to work with or competent enough to control the mind,
Though possessing the best mental faculty among all the species on the planet yet man suffers most from low points of depression,
There is no such mental exercise to develop that strength of mind but concentration with easy mode,
Right concentration makes man calm and helps to accomplish with self,
May Lord bless all,
Thanks, please
