Jai Sri Ganesha,
The whole phenomenal universe exist within self, and man may experience it in dream as well as wakeful state, but there a threshold of the two which matter most to man to enter in zone for the cause,
Mind of the man is infinite in self and possess past, present and future in hidden format but man of realization can make it to the relevant truth from it through respective discipline,
Indeed very tough subject for worldly man that extrovert but introvert,
Mystics and saintly souls feel it easy to reveal the requisite from the this infinite vault within self,
May Lord bless all,
Thanks please
