Ive just done an article myself on perspective and seeing things as they truly are. The past does exist but can only be acknowledged as that and it cant be changed - but we can be grateful for everything we have encountered, good and bad, because it has taken us to the point in life we are NOW :)
The future is simply a projection in our minds of what we are asking the universe for, only limited by universal laws!
Love your work Jeff and will be following! :)
