Realizing Non-Duality

All our lives are a series of experiences. Every experience is different from every other experience. Experiences come & go. Each experience has two parts, a changing part & an unchanging part. Objects of experiences are changing and the awareness of all the experiences is the unchanging part.
Dreams come when one is asleep. Mind generates dreams. But the unchanging awareness is still there in the background. The same awareness is there in the waking life and in  dream state.
Deep sleep is not the absence of experience, it's an experience of absence. Deep sleep is not unconsciousness. It is consciousness without an object of consciousness. It's a container which is empty.
In all the three states of daily existence, waking , dreaming & Deep sleep , one thing is common, that is the unchanging awareness . Because of which through the mind & sense organs , we experience the waking world. Because of which through the mind & sense organs , we experience the dream world. Because of which when mind & sense organs are shut down in Deep sleep , we experience the blankness. That unchanging consciousness is who you are. Not this waking body, body is physical. You are not a body with awareness. You are the awareness in which body is experiencing. You are the unchanging awareness in which the body is experiencing. Same is the case in dream and Deep sleep.
You the consciousness neither appears nor disappears, like the sun , it neither rises nor goes down, it's just an illusion created by the rotation of the earth.
