Life is like an illusion within an illusion.
It's like seeing the moon and its reflection in the water.
The moon represents consciousness, or our essence, which creates all the forms that appear to be real, like the reflection on the water.
But if you try to grab it, you'll just get wet because the moon and its reflection are illusions.
When two people walk along the river, they both see the moon "follow" them, which represents the illusion of an illusion.
Every life creates its illusion from the original illusion of consciousness, which we call life.
