We are the bodiless Self in dreamless sleep

We abide in dreamless deep sleep without being aware of our body. We recollect after waking up, that we slept happily. After waking up, we see that our tiresomeness has vanished. So, there was cessation of misery and simultaneous rising of joy in dreamless sleep. If we inquire as to who experiences the 3 states of dream, dreamless sleep and wakefulness, we will enter into dreamless sleep with awareness.
