Consciousness is not personal. Human consciousness is just an expression of universal consciousness, which pervades the entire universe.
Eckhart TollePick up any history book, and I suggest you begin with studying the 20th century, and you will find that a large part of the history of our species has all the characteristics we would normally associate with a nightmare or an insane hallucination.
Eckhart TolleSo give your complete attention to what you feel, and refrain from mentally labeling it. As you go into the feeling, be intensely alert. At first, it may seem like a dark and terrifying place, and when the urge to turn away from it comes, observe it but donโt act on it. Keep putting your attention on the pain, keep feeling the grief, the fear, the dread, the loneliness, whatever it is. Stay alert, stay present - present with your whole Being, with every cell of your body. As you do so, you are bringing a light into this darkness. This is the flame of your consciousness.
