when we are speaking of time as in past, present and future, we must keep in mind that manifesting doesn't happen linearly. time — the way we know it — doesn't exist. we only ever experience consciousness, therefore we can only experience it now. we are defined by what we are conscious of in this given moment, not by what we used to identify with in the past or what we are going to identify with in the future.
there is no objective past.
what is our past? how do we know that it has existed? well, memory. again, manifesting is a process that is enabled by our consciousness. what we are conscious of — or in other words — what we have been conscious of in the past only exists or continues to exist the way it does because of how we choose to remember it aka how we choose to be conscious of it. you could say that the past is an illusion.
dwelling on the past, dwelling on past mistakes that have been made, and so on means to dwell on a state — an unfavourable state. if you repeatedly return to that state, you become aware of it once again, you experience it in your imagination and relive it. and, well, you embody that version of yourself again and what used to be a "past state" becomes your "present state". when you dwell on the past, you re-identify with the past version of yourself and bring them "back to life". why? because as we already know, what we are aware of being now manifests. "because our thoughts of the past that we dwell on, do not recede but precede in our future." — edward art
choose what you want to remember.
now, what does this mean? since we are all the conscious creators of our lives and the outer world is just a reflection of our inner world, we need to pay even more, actually most of our attention to our awareness. you get to choose what you want to remember, as "there is no difference between an 'imagined' past and a past you think you experienced". — vesora, my beloved.
you are not who you were once.
past and future — just like present — all exist within you, your mind, your imagination. you don't have to be tied to the past. you don't have to declare it as true if you no longer desire it. you are not obligated to deem it as real. and remember, no one can forcefully try to associate you with your past if you don't want it!
there is nothing to regret.
don't feel ashamed of yourself and of what has once happened to you. don't beat yourself up, don't complain about the past, don't feel sorry for yourself and use that energy to create a new, better version of what has once existed or happened. because, again, past mistakes (made by you or others) don't define who you are now.
change what has happened.
see, the 3D is a the physical product of the imaginal acts made in the 4D. it doesn't exist on its own, nor does it have to remain the way it is. and who is in charge of it? you! so you decide what is going to be a part of your life, what has been a part of your life and what will be a part of your life. all change that results in the physical world has to be imagined in the mental world first. that's how you manifest — that's how you decorate life.
be in charge of your story.
knowing that your past is whatever you make it and only exists in your mind, it quite literally means that you carry your "story" within you. it's like your whole past can be rewritten whenever you feel like it and no one can take that away from you. no one can influence you or take away your power as you and you only are in control of your path!
you can change what you want to be aware of any time. you can always choose to rewrite your entire story, to add an unexpected plot, to end and start something new, to add a side story, ... to do whatever the hell you want, simply because you can and you will! let this be your wake up call to finally move on, forget about the history you are clinging on to and imagine a new story. leave the past as it is as it can no longer harm you. don't go back to it, don't look back, just move forward.
