Everything is in the past. You can prepare, hope, wish, dream, plan, expect, and assume the future...but all of that is behind you, and just a past notion. As I type these letters, they are all history. There is no present, because every single instance has gone by. Every spec of time is behind us. It is all gone, and just a memory.
Do you follow? Can you dig? Capiche? Comprehende?
Quantum Physics dicta's this. Everything is gone. There is nothing but the past. It also begs the point of knowing your history, because it is all we really have. Our shared perceptions are the bond that keeps things flowing, so that the illusion of the future becomes the reality of our past; or the reality of what we call the present.
Time...it's just in your head. Your words, your thoughts, your actions are indeed time capsules for others to react to, to create more past memories. They are important because they dictate how others will react, teach, endure.
Time...calendars....math, are all man made constructs to deal with not walking around in a complete fog, or reference point. The quality of life...improve it, but making your time capsule better and better.
No I am not drugs. Uh huh - yep!
