realizing the life

Yes and no.
Events are partially determined in present life.
How much is a "GOD's SECRET".
It can vary from 0% to 100%.
And the component of predetermined events is due to our previous deeds in
previuos birth.
The "time of occurence" of "effect" of "cause" can vary significantly, it has
no limit and decided by "type" of "cause".

And I don't have any idea of interpretation of any particular type.
But I can say that number of types is infinite.

There are some future prediction methods in practice around world. I don't
know about their genuineness.
But I have heard some predictions become true and some comes out to be
wrong or partially wrong.

So, the reason that sounds to me is:
When component of "predetermination" is more effective than
"present works" then they come out to be right and vice-versa.

MORAL OF THE CONCEPT IS :
None of our deeds is wasted (be it goood or badd).
So, If you have done hard work and got no results,
still keep doing with your gut.
