You are immortal awareness that surpasses all form. That is not a metaphor or just an abstract concept- you actually surpass the entirety of your physical experience and all the form in it. The only reason you may not be aware of that fact is that you agreed to be bound to the constraints of having a defined experience within form, and that experience requires a limited physically focused stimulus-set, understanding, and memory. The fact you agreed to have this experience does not change the much more fundamental fact that you actually are an immortal spirit who surpasses all of the form.
The experience of form can be very rich, very convincing- and at times, very painful. We end up quite naturally believing that the scenery of the stage is real. We go very, very deep into the illusion. As we do, we artificially define ourselves by choosing some form (ideas, identities, thoughts) over other form (contrasting ideas). This is all expected and natural, except that we have gone so far into the illusion that we have “lost sight of the forest for the trees!” As the world challenges us deeply, we end up taking shelter within the illusory forms of the ego to stay safe and avoid pain. And as we do that, we naturally end up rejecting parts of our experience.
When you reject your experience, you are choosing illusory form over the infinite formlessness. This is because when you reject something you are choosing to stand against some form, and that can only be done as a form itself. Your consciousness ends up lending credence and solidity to the form that it is trying to stand against. As the form strengthens, so does the (typically negative) experience that it brings.
For instance, if someone perceives what is occurring in the world as terrible, and rejects it, then he or she will be giving energy toward that negative perception and will experience the negative, constricting emotions that go along with that rejection. If someone perceives that they must struggle, then they will experience struggle. If someone rejects their body, then their experience in it will be more difficult. Rejection is a “low vibration” energy, because it is an occurrence of some part of All That Is temporarily turning against itself. Acceptance- also called Love- is a “high vibration” energy, because it aligns with the innate natural unification that exists at the deepest level of our connection with All That Is. Rejection is an expression of fear; acceptance is an expression of love! (Yes there are times that it is proper to “reject” something unloving, or to intercede to stop violence- but here I am speaking about rejection at its most fundamental.)
The source of all power lies beyond all form! Acceptance then is regaining power: by relinquishing your need to resist “what is,” you automatically take a step away from the illusion of form and naturally move closer towards the infinite, powerful, and peaceful formlessness that gave rise to the form in the first place.
