During Yoga Nidra, we let our awareness wander through the whole body. While doing so, we move through different stages of consciousness just as in sleep: We shift between the waking state, dream state, and finally to deep, dreamless sleep. It creates deep relaxation for health, mental peace, and higher awareness and has been quoted to say that it is a practice of self mastery of the autonomic nervous system.
Relaxation exercises are used to prepare the mind and body for Yoga Nidra by balancing the right and left hemispheres of the brain and stimulating the subtle energies of our vital force, the Prana.
It’s said that 1 hour of Yoga Nidra is as restorative as 4 hours of sleep. What does this mean? By receiving the proper rest, we enhance functioning of the immune and metabolic systems. In turn, this improves our overall physical health and leads to higher energy as well as fewer colds and infections of all types. Rest also improves mental health, eliminating brain fog, insomnia, anxiety attacks, PTSD and depression.
We engage in simple breathing exercises to release tension and trigger the nervous system to induce a state of parasympathetic activation.
Creating a Sankalpa (Intention or Resolve)
This intention is something we wish to manifest in any area of our life or a quality we wish to cultivate and/or embody. For example, someone might want to manifest fearlessness, courage, inner peace, or fulfilment.
Rotation of Consciousness
The primary objective in this stage is to isolate the mind. The mind is focused, alert, and separated from external stimuli. We separate from the body, from the senses, and from their need for attention. So we create command control over the sensory mechanisms of the physical body, specifically through exercises which deal with the mapping of the brain and opens the gate to the contents of the subconscious and unconscious levels of mind.
The science behind this stage is simply to make use of the
principle of homunculus, or the walking sensation through the cerebral cortex.
The mapped stimulation through the brain relaxes the motor and sensory regions,
thereby relaxing the body and the mind.
“A cortical homunculus is a pictorial representation of the
anatomical divisions of the primary motor cortex and the primary somatosensory
cortex, i.e., the portion of the human brain directly responsible for the
movement and exchange of sensory and motor information of the body. It is a
visual representation of the concept of ‘the body within the brain’ — that
one’s hand or face exists as much as a series of nerve structures or a “neuron
concept” as it does in a physical form.”
Awareness of Prana
The objective here is not only to enhance our ability to be aware and connected to our emotional responses, but also to work with the subtle body. We want to become mindful of the realms that lie beyond body and experience the pranic tide of breath without judgement.
Awareness of Feeling and Emotion
Our aim at this stage is to use the interaction of polarized emotional experience through a type of word association. We want to dissolve our attachment to emotional and conditional programming that lies hidden from conscious awareness in the subconscious mind.
With detachment and without fear we observe the polarisations then seek equilibrium to their experience to culminate indifference. Experiencing both waves of a feeling or emotion can have significant impact on releasing stored effect of past experience. We simply invite without added distortion what ever may arise remaining fixed on observing the intensity, and flavour of each experience and even where in the body it’s centred.
At this stage, we access and work with contents of the unconscious mind and samskaras which are our mental and emotional patterns, individual impressions, ideas, or actions. Together, our samskaras make up our programming. Here, guidance through a series of archetypal images or a guided visualization in form of a vivid journey will evoke responses in our relaxed mind. We cleanse and heal the mine field of deep-rooted conditioning.
The Final Step
We revisit our intention (sankalpa) and plant it into the field of the unconscious mind. We then return awareness back to the body. Yoga Nidra takes us through a magical process of releasing the physical body, quieting the brain waves, moving towards a calm theta state.
