Sit in a chair, spine upright, feet flat on the floor. Rest your right hand in your left. Don't cross your legs or interlace your fingers - anything that falls asleep will pull your attention into managing it instead of practicing.
Close your eyes. Bring attention inside the body. Simply observe. Don't judge what you find there.
Notice the flow of thoughts and emotions as they move through you. You don't need to chase them or elaborate on them. Just be receptive. Let them pass.
Your mind will start telling you stories - about physical sensations, about something unfinished from before you sat down, about almost anything. Let the stories arise. Acknowledge them. Don't go with them. Rest your focus in awareness itself, and refuse to be pulled into the distraction.
As you release each thought and each story, notice a deepening beginning to happen - gentle and slow at first. As you stop focusing on the objects passing through your awareness, you will start to notice awareness itself.
This can feel slippery. You have it, and then it's gone. You'll want to go searching for it, chasing it down the way you'd chase a thought.
Don't chase it. Return to being aware of your awareness. It isn't something separate from you that you need to catch. It is you. Rest here - in the stillness underneath the silence. No thoughts required. No words required.
Stay in this stillness, without moving, for the rest of your sit.
When you're ready to come out: let feeling return to your feet, your hands, your face. Take a deep breath. Open your eyes.
This practice asks less of you than it sounds like it does. You are not trying to produce a state. You are simply noticing what is already watching everything else.
