we all are trend to grow,to move further.A child grows to a person,a bud into a flower`but ever any one looked back that where is source? everything changes our look,our character, then what remains the same?which power is helping us to grow?This questions end in a words "Aham Brahmasmi" means Ami Brahma.Thats means the Knowledge we are realizing in the every passing moment was already stored within the form of a baby.As we grow up and our knowledge gets accessed by all the process.
So when we will realize that everything is inside we have to only focus on the particular subject.Its like a cd of a film.The total film is stored inside the cd.We are viewing that part which is focused on that particular moment.
