When we are awake, our minds are filled with ideas of who we are that we learned from the world around us.
When we fall asleep, our minds start to detach from these acquired thoughts and belief systems. In this state, we return to our original being that is just pure existence. This is why sleep is so peaceful.
We can become our true selves in the awake state when our minds drop our acquired thoughts and beliefs. When we lose the idea of ourselves, the mental concept of self disappears and we discover the true being of ourselves that is free of preconceived ideas. We then become pure awareness, sensing without knowing. This is the inner peace that is always available to us when we quiet our minds and live in the present moment.
We are that awareness. The Universe has become aware through us.
