Koshas and the Vagus Nerve

A Review of the Koshas

The concept of the “koshas” in yoga philosophy refers to layers or sheaths that describe the various parts of an individual’s consciousness and existence. The koshas represent different dimensions of the human experience, from the most physical to the most spiritual. There are five koshas, each are distinct but also nested within the other.

In yoga therapy, the Koshas are the framework used to co-create a plan for helping a person to achieve more balance and calmness in their lives.

Here are brief descriptions:

  1. Annamaya Kosha (Physical Sheath): This is the outermost layer and pertains to the physical body. It encompasses the physical organs, systems, and the overall body structure. It is associated with the physical sensations, experiences, and health of the body. The state of the Annamaya Kosha can influence one’s overall well-being, energy levels, and vitality.
  2. Pranamaya Kosha (Energetic Sheath): This kosha relates to the energetic body and encompasses the various energy channels, or “nadis,” and energy centers, or “chakras.” It is associated with the flow of vital life force energy (prana) throughout the body. The state of the Pranamaya Kosha can influence one’s vitality, emotional states, and overall energy balance.
  3. Manomaya Kosha (Mental Sheath): This layer represents the mind and mental processes. It includes thoughts, emotions, beliefs, memories, and perceptions. The state of the Manomaya Kosha can influence one’s cognitive functioning, emotional well-being, and mental clarity.
  4. Vijnanamaya Kosha (Wisdom Sheath): This kosha is associated with intellect, wisdom, and intuition. It encompasses higher cognitive functions, discernment, and a deeper understanding of oneself and the world. The state of the Vijnanamaya Kosha can influence one’s ability to make sound decisions, seek inner guidance, and cultivate wisdom.
  5. Anandamaya Kosha (Bliss Sheath): The innermost kosha represents the state of bliss, joy, and interconnectedness. It’s associated with a profound sense of contentment and spiritual fulfillment. The Anandamaya Kosha is often considered to be the closest to one’s true nature or higher self.

Enter the Vagus Nerve

The vagus nerve is a crucial part of the parasympathetic nervous system and plays a significant role in regulating various bodily functions, including heart rate, digestion, respiratory rate, and emotional responses. Its activity is closely linked to the body’s stress response and relaxation mechanisms. The vagus nerve has a direct influence on the autonomic nervous system, which in turn can impact the different koshas. In yoga we might describe the activity of vagus nerve as an energy system, and as the fluctuation of energy.

Making a connection between the vagus nerve’s activity and the condition of the koshas within an individual:

  1. Annamaya Kosha: The vagus nerve’s influence on digestion and metabolism can impact the physical body’s functioning. An overactive vagus nerve might lead to digestive issues, while a well-regulated vagus nerve can promote healthy digestion and overall bodily function.
  2. Pranamaya Kosha: The vagus nerve’s role in regulating heart rate variability and breathing can influence the energy flow within the energetic body. Balanced vagal tone can support a harmonious energy circulation, while imbalances might lead to disruptions in energy flow.
  3. Manomaya Kosha: The vagus nerve’s connection to emotional responses can affect mental well-being. A balanced vagus nerve can help regulate emotions and stress responses, contributing to a healthier mind.
  4. Vijnanamaya Kosha: The vagus nerve’s impact on cognitive functions can influence higher-order thinking and discernment. Optimal vagal tone can contribute to clear thinking and better decision-making.
  5. Anandamaya Kosha: The vagus nerve’s role in promoting relaxation and reducing stress can create an environment conducive to experiencing states of inner bliss and contentment. A well-functioning vagus nerve can support spiritual practices and a sense of interconnectedness.

A conceptual connection can be made between the koshas and the vagus nerve’s activity. Science continues to describe the autonomic nervous system (ANS) in more detail, as we gain a greater understanding as to how thoughts and emotions effect the ANS. Research into vagal tone, heart rate variability, Polyvagal Theory, trauma, PTSD, depression, auto immune disease, and other areas continue to point to connections between ancient wisdom traditions and modern science.

Annamaya Kosha – Our PHYSICAL Body

Yoga in the Physical Body

The practice of yoga is probably best recognized for what it “looks like” in the physical body. Yoga asanas, the yogic postures are recognized immediately in American culture. Who hasn’t seen a picture of someone standing with wide legs, one knee bent, with their arms extended out to their sides? And then thought, “oh, they are doing YOGA!” This physical practice of yoga is an activity for our physical body, for our Annamaya Kosha. Annamaya Kosha is the layer, or part of ourselves that stands apart from other aspects of our being. It relates to our physical body.

Names for the physical body and for the other five “bodies” are broad categories of our being. These five layers or Koshas help us to recognize the unique and important aspects of these different parts of ourselves. They are separate parts, but completely interrelated as everything in our universe seems to be! These divisions or “sheaths” give us a way to understand and discuss our selves in greater detail. They identify the need to heal.

The Five Koshas:

1. Physical Body – Annamayakosha
2. Breath/Energy Body – Pranamayakosha
3. Psycho/Emotional Body – Manamayakosha
4. Witness/Wisdom Body – Vijnanamayakosha
5. Bliss Body – Anandamayakosha

Yoga without breathing is “just stretchin'”

One of my favorite yoga teachers is known to remind the class, in his southern way, that doing yoga without a real focus on the breath is “just stretchin’.” Even though we divide the physical body from the energy body in a list of the Koshas, we cannot separate them! With Annamaya and Pranamaya, we are moving the physical body in synchrony with the breath/energy body as if it were one thing. And it is! We move the arms up and inhale, we move the arms down and exhale. That is yoga!

Yoga therapy and balance within the Koshas

The discussion of the Koshas and of working with these layers of existence is the basis of yoga therapy. In a traditional yoga class the topics of breath, emotion, body awareness, and body wisdom are sometimes introduced. In yoga therapy, they are at the forefront of any approach. Yoga therapy starts with the Koshas. For individual yoga therapy, zeroing in on imbalance among the Koshas is where the healing begins. Group yoga therapy also uses the Koshas to identify common imbalances for which the yoga therapist can guide individuals within the group. All healing begins with balance in the Koshas.

Slowing the physical body, slowing the energy body

In the physical body we tie together breath and movement in yoga. Using our physical body we can work to slow down each of these aspects in the practice. We slow the physical body so the breath can work to slow down our energy body. We slow the breath and the energy so the physical body will slow down and find greater relaxation. Working in tandem in this way, IS the way. The breath practice within the movement practice is actually the special sauce of yoga! And in this way we are able to notice the other Koshas as they come online, as we practice consistently.

Many paths, one mountain

This quote of many paths, one mountain reminds me of what happens when yoga becomes a regular, consistent practice. Often times we start out thinking and wanting a purely physical practice. We want exercise! As we learn the postures and begin to take the general shape of each posture, we are ready to “hear” more from the yoga teacher. We begin to hear and incorporate the instruction to move on the inhale, settle in on the exhale (or the reverse, as the posture may require). Slowly we are led up the path, and up the mountain. This mountain is the journey to our true nature. There are many paths up this mountain. Yoga is one. Spiritualism is another. Family. Community. Work. Caregiving. Birth. Death. These can all be foot paths up the mountain.

Many people, one place

All these varied paths may hold some new intelligence or understanding as we explore what it means to be human. And what it means to be our own human, individual selves. Individual but also part of the collective. There are different parts to ourselves and within our own true nature we have these layers, these Koshas. But still, being just one person (one in five, five in one, if you will!). One person as a member of a larger group of humans on earth. We are together in this one place but having many different experiences.

Yoga is the yoke

Yoga is a Sanskrit word that generally translates to “yoke.” There are many variations on this idea and what the word yoga means. My preferred explanation is that yoga is a yoke. It joins the parts of ourselves to form the whole. It creates a yoke, where the parts of ourselves are joined one to the other. This yoke forms another yoke of joining all people together in the common experience of living through and with the Koshas. We’re all one!

Namaste!
