Jai Sri Ganesha,
All knowledge that man possess reveal from the mind which ever remain connected to eternity of self,
Eternity of self is a storehouse that data base which receive and perceive whatever it exist in the outer world including varying other aspects of inner world,
This truth of eternity is alike a library for spirit to borrow or store the respective with time and occasion,
External world is nothing but suggestion for task which lies within self for inner world to glorify self in journey with life and truth,
May Lord bless all,
