The sequence of a Yoga Nidra class

A typical yoga nidra class may linger a little longer on one layer, and therefore not touch on all the levels. 

1a.   Intention (what you wish to gain in this specific practice)

1b. Heartfelt Desire (health, happiness, enlightenment...)

1c. Inner Resource (a memory or imagined sanctuary where you would feel secure)

2. Physical Sensation (scanning through the body, sensing fully until your body radiates with awareness).

3.  Breath and Energy (sensing the breath, and energy in the body)

4.  Feelings and Emotions (hot, cold, anger, happiness...  And sensing it in the body itself)

5.  Cognition and Imagery (thoughts, memories, images, and locating it in body)

6.  Joy (pure uncaused joy)

7. Witness: I-Ness (who is aware, anyway?)

8.   Pure Being, Presence, Awareness (resting as Awaring Presence, Witnessing)

9.  Heartfelt Desire (repeat it again from this perspective)

10. Coming back to the body and to eyes open state, ideally with more awareness.

This is paraphrased from the Integrative Restoration textbook.
