High
A high consciousness is about awareness and a strong connection to your inner centre. You'll know you have it when your mind is coherent, your choices are simple, your challenges doesn't cause you anxiety and you wake up feeling refreshed.

As with most things in life, there is a true and a fake version of high, and sometimes the challenge is simply to be able to separate them both. This might sound obvious. Especially if you're already in a natural, healthy high state of mind. However, if you're not, and your mind is a bit cloudy and confused this separation challenge is probably harder than you're aware of.
There are many things that could cause you to the enter a low state of mind in the first place. It could be a trauma, a fear, a loss etc. It could be. Yet we meet these people out in the world, who have experienced the most traumatic childhoods, or losses or fears we can't even relate to, and they turn out to be the most kind hearted, wise people with these beautiful sparkling eyes. How?
Having a low state of mind is, believe it not, a choice. But in order to chose, we need to have knowledge and wisdom. We can't chose right, if we don't know what right is.
I'll tell you something simple when it comes to a true and a false high.
The false high - regardless if you get it from a person, a behaviour, a substance or a situation - will give you a hangover. Without it, you'll feel weak and low. With it, you'll feel strong and... high. A true high doesn't bring you down. It keeps you grounded and calm and it adapts to your body in such a way that when you're without it, its strength still lingers in the air around you. It'll never bring you down. You'll never feel addicted and never attach. You'll just simply feel better.
The key to reach and maintain this natural high state of mind it is to take control over your life, and the only way to do that is to stop blaming others for the way you feel and stop blaming your self for how others feel. With that foundation you'll know that everything that ever happens to you is because of something that you do. From there you'll know where you have yourself, know where you are, know what you want and you'll be able to bring yourself to exactly where you want in life. Because you don't blame yourself and others, you'll live in constant forgiveness. This in turn will allow you to feel love and peace. And nothing brings you a higher state of mind than those three.
