There are many threads of reality that exist within the energetic field of a life. At any given time, there are threads that are a close vibrational match to your existing reality thread, while others exist as more remote vibrational matches. These more remote vibrational matches have a lower probability of becoming your focus probability, but they are still possible futures already in existence. Threads of reality that are close vibrational matches to your present reality are considered future probabilities. This means there is a strong likelihood you will at some point begin to shift to the timeline of this alternate reality.
In your world, a timeline shift might look like this: you are working as a yoga instructor in a medium-sized town in the Midwest. You have friends here, and a job, but you have always felt drawn to explore the Pacific Northwest. You have also considered writing a novel. One day you decide to plan a vacation to Seattle and have a look around. While there, you attend a musical concert and meet some interesting people. One of them knows of a beautiful cabin that is available on the coast. You go to see the cabin and fall in love with it. You see yourself living here, writing the novel you have been dreaming of, and getting to know new friends. You rent the cabin, return home to the Midwest, pack your bags and move. You have effectively shifted from one timeline to another.
Imagine you are that same yoga instructor in a Midwestern town and you decide to switch to a timeline where you're a physician living in Tokyo. Shifting to this time will obviously require greater effort, though it still resides within your field of possibilities if you imagine it. Whatever you imagine is a possible reality already residing within your field of possibilities. If it weren't already a timeline in existence, you wouldn't be thinking about it.
There are other, less obvious ways people shift from one timeline to another. The person who adopts a healthy diet and exercise routine has shifted to a different timeline with a different set of future probabilities. The person who adopts a spiritual path is choosing a vibrational timeline of different resonance that can, in time, allow them to shift to very different timeline probabilities.
There are many small ways you shift to different threads of reality without noticing it. This is the case when you rearrange the furniture in your home or begin to travel a different route into town. Even the smallest variation in your daily routine has the ability to create energetic changes that can lead you to choose other timeline probabilities. It is important to understand that when you create even a small change in your life, this creates new pathways in your consciousness that can effectively create a new "you." Timeline changes grow from this new version of your self.
Many people change timelines only out of necessity, when there is a crisis or other unexpected event. In these cases, the timeline shift is not always one of their choosing. Still others remain in the same basic timeline for most of their lives, with little variation in reality threads. By contrast, there are lifetimes where a person undergoes so many reality shifts it seems they have lived many different lives within the same one. Many lightworkers experience this as they actively seek new spiritual understandings and access those of past incarnations through communion with their higher self. In every case, the various lessons and shifts of a life are set forth prior to birth in counsel with the higher self and other guiding entities.
As you gain awareness of the many threads of reality that exist within you field of possibilities, you can consciously choose the thread you wish to energize. Even if a thread of reality does not seem very "probable" at the moment, you can begin to bring your focus and attention to that timeline. As long as you are willing to take action, and keep on taking action to create a reality shift, you will eventually make the shift.
When you shift to a thread that is a close vibrational match to your present one, the change may be barely detectable; when you shift to a vibrationally different thread of possibility, it may suddenly seem you are living an entirely different life.
This "quantum" reality shift takes place, for example, when a person experiences a spiritual awakening and begins actively pursuing a very different path. The shift can dramatically change their vibration and shift their focus to a timeline that was not previously a probability. In other words, it already existed as a possible timeline, but not a timeline with a high probability of becoming a focus timeline.
Another factor in a quantum shift is that you are creating a very different probable future "you." By shifting to a spiritually-awakened timeline, you inevitably undergo an identity change. As you acquire advanced spiritual understandings, your spiritual senses open. Your future self in this new timeline is now capable of communicating with you telepathically and serving as a guide. This further accelerates your vibration and path of spiritual growth. Your field of probabilities change as your awareness grows. One day you wake up and perceive the vast field of possible reality threads you can consciously choose from. You are able to access peak states of consciousness at will. You create your reality moment by moment as you pave the way for others to follow. All this is possible and more.
As you shift from one reality thread to another, ask yourself where the new thread is likely to take you, what future "you" is likely to result from this choice.
By entering the Portal of Timeline Shifts, you are able to bring your possible timeline threads into awareness. From this place of awareness, you can consciously choose a reality thread and begin to energize it with your focus, attention and action. In this way, you begin to create the self of your highest possible future, transforming your life at the quantum level.
