The concept of a being subject to causality presupposes something akin to time.
And conscious matter creates universes constantly, that appear out of the void, hence creating time and space. This would also imply that its possible not only to change the future, but also the past.
The masters advise, however, that these are distractions and that the journey inevitably leads to experiencing the void itself, hence stepping out of time and space, and consciously experiencing any aspect of time and space and consciousness one wishes to, while always remembering that one is beyond it.
Consider if this universe exists only as a simulation (I’ve met some theists making this category of comparison but with different language). The laws of physics are identical in both directions for the arrow of time, so the starting point of the simulation from the point one view of the outside universe can be any point in time from the perspective of the inhabitants.
In this case, the “before” in the outer universe is a logical rather than temporal one from the point of view of us inhabitants.

If the answer to a question of “Why [...]_1?” would be “Because there is a [...]_2 such that [...]_3 .”, then there is such a [...]_2 such that [...]_3 . (Possible exception : if “because you asked that question” would be part of the answer.)
I would suggest reading anything by Nisargadatta Maharaj, who expanded on this in detail to questioners from all over the world who came to his humble dwellings in a Mumbai tenement to observe him. I’d suggest starting with ‘I am That’, available on Amazon, iBooks etc.
He claimed to be outside of time and space himself.
