Our spiritual nature is pure consciousness. It is also pure delight since it is limitless and unlimited. Pure knowledge, endless quiet, perfect balance, invincibility, simplicity, and happiness are also characteristics of awareness. This is our true essence. Our true nature is one of limitless possibilities. We are not this body, we are not our mind, we are not even our thoughts. We are beyond all limitations, including the sense of "I" and "mine."
When we talk about consciousness, we mean that which thinks. The thinker, the thought process, and what is thought about are all part of the picture. So when we say that "X is conscious," we mean that X experiences itself as a separate entity from its surroundings. It believes it is an isolated individual with a mind of its own. Consciousness is that which knows itself to be aware. It is self-awareness.
Awareness is only knowing that you are aware. You can't go any further than that. If you try to analyze what it means to be aware, then you end up back where you started. That's why many teachers will tell you that enlightenment is not something you achieve or attain. The only thing is that you don't yet know how to access it.
The intellect is very good at analyzing things outwards from itself. It wants to understand everything else but itself.
A pure spirit is someone who has good intentions. It is someone who does things for the sake of doing them rather than for the sake of merit or position. It is a soul whose decisions are made from inside, from what that soul perceives to be good or right, rather than for the sake of attention or fame. A pure soul would never do anything to harm others nor would it desire to.
A pure soul is also called an immortal soul because people with such souls will never die. However, this doesn't mean that they won't experience any form of emotion because even the most peaceful person on earth can still have a sad day.
People with pure souls are found in every culture across time and space because they're easy to recognize. They are the ones who make positive impacts on those around them both large and small because they have light within them that makes them want to help others.
People with impure souls tend to do bad things that hurt others either intentionally or unintentionally. They may do things for attention or praise but then feel guilty about it later. Sometimes they might do something wrong just because they can get away with it.
Impure souls are responsible for most evil in the world today including violence, abuse, harassment, and more. There are also cases where individuals with impure souls have done good things too like saving someone's life by giving their blood plasma or helping someone who was struggling with addiction.
Pureness is the state of being pure or free from contamination or adulteration.
The word "pure" can be used to describe something that is without contamination or adulteration. For example, "a pure strain of bacteria" means a strain of bacteria that is not contaminated with other kinds of bacteria. Or, "his actions were pure of malice" means that they did not include any other motives besides hatred.
"Pure" can also be used to describe a material that is not mixed with anything else. For example, "a pure gold ring" means an all-gold ring that does not contain any other materials. Or, "her music was a pure expression of her feelings" means that it did not contain any references to other artists or styles.
As well as describing things that are without contamination or adulteration, the word "pure" can also be used to describe people who have good characters. For example, someone who is "known for his pure heart" would have an excellent character.
Being or existence, as the highest metaphysical principle, IS its own essence; there is no other essence or essences, according to the Indian advaita Vedanta school (many Indians and Easterners contribute to Quora). The same may be stated of awareness. Are they one in essence? But they both require an experiencer.
Consciousness is experience, and what experiences something? A mind. So yes, the mind is the essence of being aware and conscious. But you cannot say that the mind is the essence of everything because it includes me and I can think of other things besides thoughts. The mind is the essential component that allows for experience. It is what we call "being aware" and "conscious of".
We tend to use the words "essence" and "existence" interchangeably, but they are not the same thing. An essence is what remains constant through change and variation. So the essence of love is not love itself but its reflection in human behavior, which varies from person to person and culture to culture. Existence on the other hand is a state or condition of being actualized or manifested. So the existence of love is demonstrated in how others treat you when you show them that you care about them. This manifestation of love can take many forms: gifts, acts of kindness, phone calls, etc.
