Your mind typically never stands still. Just observe your mind this very second, it is constantly abuzz and moves from side to side and up and down. But through deep prayer, your mind starts to be still. Your mind moves side to side in time, but your soul is “still” in eternity. The biblical quote about forgetting the past is what Jesus meant when he said said, “Let the dead bury their dead”. Just try to recall that the past no longer exists anywhere. The ONLY place it is existing is in your own mind! You are not an insane person. Don’t stare at ghosts of the past that have long since disappeared. Why continue to chew on it?
Say you have a meal and throw out the leftovers. After a day or two, do you go out to the garbage can, sift through the rotting meat and maggots and chew on the decaying matter? Why go on and eat it? This is what you are doing when you sift through the past. It is all just in your mind. It exists nowhere else. The future also exists in your mind. Why do you go on thinking about the future? And why are you dwelling on your future. What can you plan for it? If you plan, most likely inevitably, you will be frustrated, because God and the Universe has His own plan. Why do you try to make your own plans against it? And again, why would you struggle against the past? Can you do anything to change the past by thinking over and over and over about it?
Accept your destiny from God and/or the Universe. To accept things as they are is to be happy. As we read before, “he who accepts things as they are, The Fates will lead, those who resist, the Fates will drag…” To be reborn is to completely and utterly accept your destiny as given by God. That means accepting the past and being completely ready for whatever comes in your future. Completely and humbly and without resistance…
Non-acceptance is like a drop of water on a wave in the middle of the ocean, trying to decide it is going to go somewhere other than the wave pattern or the weather patterns or the underground formations (like an earthquake) that influence the entire ocean. The drop of water must realize it is just part of the entire ocean.
It cannot dictate to the ocean where it wants to go. Say the wave brings the drop of water to the east, then the currents change and the drop of water begins to move to the west. Then should it protest and argue to the ocean “Why didn’t you move me to the west in the first place?” The ocean has its own course, its own movements. Should each drop of water begin to complain about what the ocean is doing?
Remember that the whole of existence, the Universe, God, is much wiser than you. Don’t bother yourself, killing yourself thinking about it. There is an old Puritanical saying, “It is a sin to think and feel sorry for yourself.” If you make it a nasty habit, then it is not any better than having an addiction to cigarettes, alcohol, or other drugs. You are addicted to obsessing about your past and worrying about the future.
Again, it is a sin! Yesterday, you must have worried incessantly about today. But what happened? Did any disaster happen? And was it worth it to miss those present moments for a future that yielded about no differences anyhow? And today you will likely again miss your present moments for tomorrow. If you have a fixed way of thinking in such that you are always thinking about tomorrow, then just when do you plan on living?
