Jai Sri Ganesha,
Purification of intellect is a concerned subject for men,
But intellect is not in reach of men in any case, an external agency in truth with doom and destiny influence it respectively,
Yet men can not afford to lose heart on the subject, as when all other aspects attain sanctified truth through respective discipline, intellects too follow the course,
He, who has purified his intellect though through indirect practice may make it to the tune of that meditation which leads the spirit from the forefront to that threshold of journey,
May Lord bless all,
Thanks, please
