"Recently I have been really trying to deconstruct this idea of perception... What is perception made up of? Sensibilia, Intellegiblia and Transcendia are three components. Sensibilia being the physical realm of perception (perception through the body). Anything that is a sensual experience falls into this category. Movement itself falls within sensibilia, the vibrational energy that flows throughout life. So how do we make sense of all of this....? Intellegiblia! Intellegiblia is the realm of perception that is linked to thought. A realm that is beyond the tangible physical aspects of things. Anything can exist within this realm... if you think it, than so it shall be! This realm is beyond the objective world and is non- tangible and subjective. It includes the mind within the body, but also the mind beyond the body. But.. what does this mean... beyond the body? Well, that is transcendia. Transcendia is the perception driven by spirit, by the soul. It is the essence of you in perception. When you experience life in the realm of transcendia, you experience life as spirit. "
