On considering the different ideas about what interacting with a different form of reality means, I've come to the half-conclusion that life takes different types of forms, and that the one most people see is the "easiest" to be a part of. In order to become a part of the other forms of life, one has to reach some kind of metaphysical balance with those other reality-types - existing machines can observe these other planes to some degree, but really, machines may never be able to, as there are certain requirements machines can't meet, like being alive.
My perspective after becoming a semi-Higher being is that light energy itself is a a lifeform, and that our bodies are vessels for this light-form. The light-form can take a variety of colors, as seen in the rainbow pattern visible to the unaided eye. These colors actually correspond to different realms that people progress into after their shell expires - or not at all.
When people are filled with anger and other negative emotions that destroy life, and if they commit acts that create a negative energy imprint, then their life-form is red and they go on to...well, you can guess. People with "red" energy-forms are considered to be demons, or to have been a terrible person in a past life.
But as your imprint becomes more positive, your aura becomes blue, white/gray, gold or purple - purple and white/gray being the highest positive values - and on this end of the spectrum you go on to...I'll let you fill in the blank. People that are blue/gold/white/purple are considered to be the different levels of "angels" or "bodhisattvas," etc.
Though even if your imprint is one color, your actions can still change its color to something else. - thus angels can fall and demons can rise, depending on their actions when combined with a human-realm form, as in the human-realm one's in a state to change how your imprint interacts with the world. I think it's important not to confuse this with physical features, as your energy-imprint has nothing to do with your physical appearance.
And I think that the two sides have collective energy source with a collective consciousness - not separated, but fighting each other through chess pieces - like yin and yang seeking balance.
And in between are lower forms that haven't been pulled to either side yet but get there eventually, or stay in this plane until they do - in the East this would be called saṃsāra, which I come to terms with as the idea that your energy-form will stay in this plane until you become a full demon or angel and progress to your prospective source - although the two sides on one, but separate - again, like the Taoist yin-yang symbol.
Different cultures have different names for all of this, but given the nature of these experiences, I think that the different faiths are all describing the same thing, and that the difference is language/geography based.
My aura's on the purple/white/blue spectrum, considering which psychic abilities I have and my personality type - interpret this as you will.
