You have to remember that in essence you already exist in those future events....

True clairvoyance/divination at a higher-self level (towards the divine) provides clarity on future events....

Psychic divination based on the abilities which are available within the incarnate-self... is often quite cloudy and rarely fully accurate. (since it is focused purely on where the incarnate self is now)....

So to answer your question... the point is - know thy self :)
