Is it real that one can know the past and future of oneself through deep meditation and self realization?
The short answer to your question is "yes!"
There are many examples in Autobiography of a Yogi, which illustrate this ability.
We might say to ourselves, "Oh, but this is what a great God-realized Master can do, not a mere person like me." But "Master" means "self-mastery" and that is both our duty and our destiny.
The great Ones often say: "There is no past or future. Time is an illusion. Therefore, live in the Eternal Now, where perfect and ever-new, never-ending bliss resides."
Deep meditation will help you achieve that state very quickly.
