Well, I think what Brysing's trying to say here is that there may not be a spell to physically see the future like you're watching a movie. And to a certain degree, I do agree with him.
There are things like premonitions and astrology. Even tarot. But none of them provide a 100 per cent guarantee of what the future may hold.
Someone once said that the present is a result of all the thoughts in the past that you've spent your energy on and the future will be the result of all the thoughts in your present. If this holds true, then those obsessed with trying to see the future, will still be looking for it when it arrives. In short, a life in transit, just waiting to see what's next. A life of anticipation and sometimes even fear. Such a waste, what's say?
The magic is in the now...and how you deal with what's happening, right now. Not freaking about what may or may not happen. Chill, relax... easy does it.
