Q: Why does Gestalt Theory seem so accurate when used to describe the different perceptions of reality?
A: Gestalt theory explains how the physical mind interprets information supplied via the physical eyes. However, what Gestalt did not realize is that the physical mind also works this same way when interpreting input received via other senses, non-physical senses.
When you view the physical world via your senses (physical senses and non-physical senses), the physical mind still seeks to find patterns that fit within its framework of understanding , its vision of how the world and reality function.
This is why it is so important to free the mind of these barriers. If you can let the mind free, then the more honest the experience will be for you. As long as fears or restrictions exist within your mind, they limit your view, your perspective, and they allow the physical mind to remain attached to its preconceptions (of how reality works). They also act as filters, permitting in only those concepts and ideas that fit within the paradigms of the physical mind.
For instance, if you see a being of light, but the filters of religion remain firmly in place, then will that being be assigned the role of angel (or demon, if you countenance them to be of evil intent). Yet, in fact, the being may merely be a non-physical manifestation of one from a different plane of reality, one [reality] whereon physical bodies are not used and so does the being appear in its most common guise.
The physical mind is constructed and adapted to seeing patterns. That is how the mechanism has remained alive. Like all creatures of physicality, the instinctual center is to protect and keep viable the physical form. The mind sees and interprets the “patterns” of the world around it and whether the patterns are harmful. Some of the patterns come from the instinctual center, while others are learned either through various incarnations or from parents, siblings, church, work, or others.
Those patterns learned from others—patterns such as the boundaries of life that religion or science instill, or the boundaries that parents inflict on children—can be overcome. Other boundaries, such as those instilled by the instinctual center, an also be overcome, but it is more difficult to do so, as the memories are inside and so the fears are remembered not learned. But fear can be overcome when a pattern is viewed—such as a being of light. Then does the physical mind flash through all those patterns stored within in order to match something known to something unknown. If nothing fits exactly, and the fear is strong, then something close (such as angel or ghost, whichever is less likely to induce more fear) is accepted. If fear of not matching it is not great, then questioning and theories may commence, and alternate explanations sought.
The experience is put down as anomalous and is either forgotten or another similar experience sought, or other similar [incidents] are looked for that were had by others so that you do not feel alone in your experience. Also, do you seek insight and perspective from others who have had similar experiences. You, in the physical plane and all of us in all realities and planes, are curious and we are constantly seeking answers to questions we have yet to ask.
