Shushumna nadi runs parallel to the spine, along the central axis of the body, with the ida and
pingala nadis wrapping themselves around the staff like a DNA double - helix.
The vibrational quality
of pingala is represented by the color red.
Bringing ida and
pingala into equilibrium is a major focus of hatha yoga — so important, in fact, that the term hatha symbolizes this balance.
Spiraling up the central axis from the base of the spine, ida and
pingala cross paths at each of the seven major chakras.
In life, ida and
pingala dance with each other for dominance, but the ultimate goal is balance.
When either ida or
pingala reigns, we engage with the world, but during the short periods when they flow equally, sushumna draws awareness inward, creating a quiet inner joy.
Like the eye of a hurricane, sushumna — the channel of energy flowing along the core of the spine — is said to be unaffected by the powerful energies of ida and
pingala swirling around it.
Ida, as it is known, ends in the left nostril,
pingala terminates in the right, and sushumna ends at the base of the nose between the two nostrils.
The interaction between ida and
pingala corresponds to the internal dance between intuition and rationality, consciousness and vital power, and the right and left brain hemispheres.
In fact, some yoga teachings hold that as long as either ida or
pingala predominates, sushumna stays closed and the power of kundalini lies dormant.
As we manipulate the flow of breath through the nostrils, we access the Surya (sun) or
pingala nadi through the right nostril and the Chandra (moon) or ida nadi through the left.
Ha represents the solar qualities, the vital force,
of pingala; tha represents the mind and the lunar qualities of ida.
You can also bring awareness of ida and
pingala into any asana practice by pausing between poses to notice which nadi dominates your breathing.
The ancient texts report a staggering 72,000 individual nadis, but yogic philosophy focuses on the largest and most important three channels: ida,
pingala and shushumna nadis.
Both ida and
pingala have their own physical, metaphysical, and psychological components.
- Right nostril, Surya or
pingala: breath is heating and energizing; when this side is overly dominant anger, hyperactivity, aggression, or elevated blood pressure may result.
Activities such as exercising, controlling an automobile, prescribing medicines, stimulating digestion, performing physically demanding tasks, arguing, inspiring others, going to sleep (warmed by an inner fire), and undertaking any difficult or challenging action are more likely to succeed when the right nostril, or
pingala, is active.
Yoga texts, such as the Shiva Svarodaya, have observed that the flow of energy through ida and
pingala is rarely equal, and that this can be noted in the nostrils.
This is the pathway of the bladder meridians in Chinese medicine, which Motoyama has identified with the ida and
pingala nadis so important in yogic anatomy.
This results in personality, behavior, and health issues that can be called ida - like or
pingala - like.
Awareness of the ida and
pingala nadis can help balance your practice — and clear the way for spiritual growth.
Are you agitated and active (
pingala - like) or calm and receptive (ida - like)?
In addition to using Nadi Shodhana, you can experiment with using the asanas themselves as a method of balancing ida and
pingala.
The ida (comfort) and
pingala (tawny) nadis spiral around the sushumna nadi like the double helix of our DNA, crossing each other at every chakra.
The most powerful method of balancing ida and
pingala is Nadi Shodhana, alternate - nostril breathing.
This practice is effective because the ida nadi is directly connected to the left nostril, and
the pingala nadi to the right.
If you visualize the caduceus, the symbol of modern medicine, you'll get a rough idea of the relationships among the ida,
pingala, and sushumna nadis.
If the left nostril dominates, ida is in charge, and you might consider focusing your attention on invigorating asanas — such as backbends, standing poses, inversions, and twists — to engage
the pingala nadi.
Balancing sun and moon, or
pingala and ida, facilitates the awakening and arising of kundalini, and thus the awakening of higher consciousness.
They are full of potential, but unless they develop
their pingala side may never manifest that potential in either worldly affairs or spiritual development.
