Here’s a big one, made easy to understand.
Your consciousness is the light in your life. Without it there is darkness.
Your consciousness is separate from your mind. Your mind is a mirror.
Your consciousness is “the light” that reflects on the mirror of your mind.
The contents of ‘the light’ cause the mirror of your mind to vibrate. If the contents of your consciousness are negative, the light causes the mirror of your mind to vibrate very differently than if the contents are positive.
The mirror of your mind reflects the contents of ‘the light’ outwardly into the world, drawing unto you like kind vibrations. And thus you have it: what you conceive and believe in your consciousness, you attract and experience in your life.
And so it is, “I am the light of the world” means that the contents of your consciousness light up your world by using the mirror of your mind to make your thoughts and visions visible.
