All there is, is NOW!

We are taught and lead to believe that we live in a linear existence, however, the reality of this existence is actually more of a spiral.  Does the past exist at all? and if so, can you change it?  What exactly is the future and how do you approach it?  We will discuss the theory that there is only NOW, and the past and future are constructs that limit your ability to see yourself as all, at once.  Confused?  Listen in.  But I warn you, you may still be confused.
