Yoga nidra is said to be as old as yoga itself; it developed as a meditation practice sometime between 500-600 CE. The first mention of yoga nidra’s purpose is written in the Upaniṣads, a series of texts that describe the nature of self realization and the universe.[note]Kamini Desai. Yoga Nidra: The Art of Transformational Sleep. Twin Lakes, WI: Lotus Press (2017: 19-20).[/note] The particular practice from which it comes is nyāsa: “to place; to take the mind to that point.”[note]Dr. Rita Khanna, “Yoga Nidra and Cancer,” Yoga Teacher Training, Aura Wellness Center, April 26, 2017, https://www.yoga-teacher-training.org/2011/04/03/yoga-nidra-and-cancer/.[/note] In aṣṭāṅga yoga, the eight limbs of yoga, yoga nidra is a practice of pratyāhāra, drawing the senses away from external stimulus and inward toward the inner workings of the body-mind.[note]Ibid.[/note] Preparation for physical death, to my knowledge, was not one of its original applications. I noticed a connection during the year in which both of my parents died, and realized that all the benefits of practicing yoga nidra to improve quality of life can be directly applicable for those who are processing a death, or who are themselves dying. 

Śavāsana, the resting pose assumed at the conclusion of contemporary yoga classes, translates to “corpse pose.” In śavāsana, the body-mind dies: to the work of the practice, and to the days, months, years, that preceded it. It ideally does not think, plan, or remember, but rather becomes quiet and receptive to the present moment. Awakening from śavāsana means waking up anew. 

Corpse pose is the position in which yoga nidra is commonly practiced. Yoga nidra translates to mean sleep: yogic sleep, conscious sleep, sleep as meditation, sleep as spiritual practice, healing sleep. I use the word “healing” because the roots of the word “yoga” — yo (yoke; bring together), ga (go—as in, do it)[note]I learned this etymology of the word yoga in 2010 during informal studies with Radhika Devi, an independent scholar, philosopher, and translator of Sanskrit poetry who shares her time between west coast Canada and Vrindavan, India.[/note] — combine to a definition similar to that of the word “healing”in the Oxford English Dictionary: “to make whole; to unite, after being cut, broken.” Sleep, even as we may think of it as a primarily physical activity, is generally known to heal the body from injury and illness. Yoga is another kind of healing: linking a practitioner with their higher self, their soul, their source. 

Śavāsana is a death: a small one, and we can practice it as often as we want to prepare for the big permanent death we will all eventually face. Sleep is also not uncommonly thought of as a small death, from which we awake each morning. Where sleep as we know it accounts only for the physical body, yoga nidra accounts for the body as both physical and energetic, made up of five layers, or kośas: the physical body (annamaya kośa); the breath body (pranamaya kośa); the intellectual/emotional body (manomaya kośa); the intelligence body or witness consciousness (vijñānamaya kośa); and the bliss body (anandamaya kośa), which connects with Brahman, the universe, or source. The main components  of a yoga nidra meditation put to sleep annamaya kośa, pranamaya kośa, and manomaya kośa (the physical, breath, and intellectual/emotional layers of a practitioner), while vijñānamaya kośa, the higher intelligence or witness consciousness, remains awake and aware:[note]These are the main components of a yoga nidra meditation, not a complete yoga nidra protocol. Elaborations on each component are based on those described in “Yoga Nidra and Cancer,” by Dr. Rita Khanna, as well as those in Julie Friedeberger, “Yoga Nidra: A Healing Practice for People Living With Cancer,” Yoga Magazine, Bihar School of Yoga, April 2008, http://www.yogamag.net/archives/2000s/2008/dapr08/yn.html.[/note]

Sankalpa

The sankalpa is an intention that the practitioner phrases as though it is already so, like a promise for the future.

Breath Awareness

Training the mind on the breath gives it something to do. It re-routes focus away from thoughts and gives the mind a resting place on a gentle rocking movement that can down-regulate the nervous system.

Rotation of Awareness

Rotating awareness throughout the body brings awareness away from thoughts and to all parts of the body, in turn. This also sends breath energy to each part of the body, promoting movement and release. Rotating awareness teaches about letting go. 

Holding Opposites

Holding opposites in awareness, such as the felt experience of warmth and coolness, or heaviness and lightness, consolidates the lesson of letting go. This practice also teaches practitioners to not get caught up in liking or disliking because every sensation, feeling, and circumstance, is fleeting and will end.

Visualizations

Practicing visualization when the body is in an open and relaxed state engages the imagination to develop images, stories, and ultimately, our realities.

Yoga nidra is a bridge by which this side is connected with the other. We cross this bridge when we meditate, and also when we die. Death is the final śavāsana; the last sleep; the ultimate pratyāhāra. Where both sleep and yoga are healing processes that in their own ways simulate death, I considered, if not for my parents, then for myself, how dying, too, could be practiced as a healing process:[note]I have broken this list out using the Physical, Intellectual, Emotional, and Spiritual (P.I.E.S.) model because these are commonly understood in the west to be the four main components of human nature. If we compare these to the five kośas, we’ll see that here, “physical” accounts for both the physical and breath bodies; that where the kośas account for intellectual and emotional processes in one layer, this model accounts for them as separate aspects; and that here “spiritual” combines the intelligence and bliss kośas.[/note]

Physically by slowing down; putting physiological processes to rest.
Intellectually by completing tasks, and moving on from what can’t be finished
Emotionally by affirming love; resolving old hurts; facing and accepting what is
Spiritually by letting go; preparing for what’s next / the unknown.

When I lined this list up alongside the many benefits of a yoga nidra practice, I noticed significant correlations:[note]Again, I have used the Physical, Intellectual, Emotional, and Spiritual (P.I.E.S.) model to list the benefits of yoga nidra. These benefits have been compiled based on those in “Yoga Nidra: A Healing Practice for People Living With Cancer,” by Julie Friedeberger, and in “Yoga Nidra and Cancer,” by Dr. Rita Khanna.[/note]

Physically:

yoga nidra calms the sympathetic nervous system (fight or flight) and activates the parasympathetic nervous system (rest and digest); slows and regulates breathing; lowers heart rate and blood pressure; and releases muscular tension.

Intellectually:

yoga nidra focuses attention inwardly and relaxes it from a near-constant state of outward arousal; builds conscious awareness of the body and clears neural pathways between body parts and the brain; integrates left and right brain hemispheres; improves concentration, learning, and memory; and trains the mind on intentional thoughts.

Emotionally:

yoga nidra bridges conscious and unconscious states of awareness; can clear the unconscious of repressed psychic matter (fears, anxieties, insecurities, grudges, regrets); and builds the ability to cope with stressful situations.

Spiritually:

yoga nidra develops discipline, acceptance, and non-attachment; activates the imagination; and awakens our higher intelligence, or witness consciousness.

Since the deaths of my parents I have often wondered: What is a “good death”? I suppose there are as many answers as iterations of the question; the only answer that sticks for me is: an intentional one, a death that I have prepared for on all levels. Yoga nidra can help us not only face our own mortality,[note] Julie Friedeberger, “Yoga Nidra: A Healing Practice for People Living With Cancer,” Yoga Magazine, Bihar School of Yoga, April 2008, http://www.yogamag.net/archives/2000s/2008/dapr08/yn.html. [/note] but also practice for it by giving a circumstance in which to experience those healing aspects of death, knowing that we will wake up afterwards and return to the business of our lives, where we will be empowered by our meditations to act as necessary toward preparation, resolution, closure, and surrender. We can begin anytime. Why not now?

With deep thanks to my yoga nidra teachers Jennifer Piercy and Misha Butot for their continuing guidance and support; and to my parents, for everything.
