There were no words for consciousness back in Biblical time. There are hardly any nowadays.
However, I think that consciousness is what Jesus was talking about when he would talk crazily egotistically about himself. He was trying to use himself as a symbol for this other consciousness and describe it through his words, so he would say things like, “I am come a light unto this world, that whosoever shall believe on me shall not abide in darkness.” (John 12:46) and “For God so loved the world that he gave his only Son, that whosoever believeth in him should not perish, but have everlasting life.” (John 3:16). Another example, “I am the way, the truth and the life: no man cometh unto the Father but by me.” (John 14: 6)
Read the Bible with a mindset of symbolic application. I think the King James version is amazing. We know these aren’t Jesus’ real words (I mean, he spoke Aramaic) but for some reason (think!), they are really significant through the ages. Imagine that, when Jesus speaks in the Bible, this many resonating cases, this is the universe’s or Higher Power in the minds of the men who wrote this. The knowledge on their higher levels spoke to them through symbols that would work for a broad swath of people at different levels, thus making the Bible “holy.”
It is not new-age think to say that consciousness is real. It can be shifted, exercised and expanded. Everyone is a spiritual person and those who have not yet, are soon to discover this aspect as well. You’ve got a brain that makes your mental body. You’ve got an emotional body. You have a physical body. Your spiritual body exists and can be improved, seeping, trickling, maybe even rushing and flooding into the rest of your life.
Wiser spiritual people (vs. the ignorant spiritual people? haha) are not ignorant of science. They are beyond science. They have a greater awareness. Yes, there is something beyond the physical world of science and the scientists are still figuring this out*. The brilliant scientists acknowledge it.
Here is why three is better than 2: It finds balance. It is love. The eye of the needle, it is the thin line between the opposites that exist in duality. It blends. It combines and makes more, thus it is creative. It sees there are many sides. It believes in the ultimate good. Three is the way to one, as two doesn’t really exist (where two or more are gathered, there is three – the relationship between the two, so two isn’t really real but everyone thinks it is). Three takes us back to one…Two is the world (and its current consciousness), but two doesn’t exist by itself due to the wholeness, and two being a split of that wholeness (which still exists). In fact, there are lots of other splits, also, that make the whole of life/love (in the larger base systems).
A person is good to live on all levels, in order to better understand this triplicity of the world and what is different consciousnesses. This is not something that can be thought so much as (Self-)observed in the expression of who you are.
*Remember that whole cycle and how science is an aspect of this? Yes, some advanced science is late in the cycle but it still does not include the whole of the cycle to the end.
