Notice this:

1. You are not the one who wakes, or dreams, or sleeps.

2. You Are the actionless and formless Mere Witness of the three common states—of waking, dreaming, and sleeping—and of all the apparent contents and “experiences” associated with the three common states, of waking, and of dreaming, and of sleeping.

3. You are not the body, or the doer of action, or the doer of even any of the body’s actions or functions.

4. You are not the mind, or the thinker, or the doer of even any of the actions or functions of mind or of body-mind.

5. No matter what arises—whether as or in the state of waking, or of dreaming, or of sleeping—you Are the actionless, and formless, and thought-free Mere Witness of attention itself, and of every apparent “object” of attention, and of any and every state of “experience”, and of the entirety of whatever and all that arises.

Always intensively “consider” these Five Reality-Teachings.

Always intensively observe and notice every moment of your “experience”—whether waking, dreaming, or sleeping—and, thus and thereby, “consider” and test and directly prove these Five Reality-Teachings in the moment-to-moment of your every kind and state of “experience”.
