Be aware of your breath while you fall asleep. The movement of your belly, the touch of the air in your nose, or the flow of air in your body.
If you meditate and fall into sleep, you will wake up meditating. That means in a subtle way, in your deep unconscious, the method continued. Your whole night became a meditation. Your sleep will be of a different quality – more silent, more relaxed, more rejuvenating.
And for six or eight hours, subliminally the witnessing continues.In the morning when you become aware that you are awake, you will be surprised! You are witnessing your breath.
