The astral tubes made of astral matter that contain psychic currents are known as nadis.
The Sanskrit word 'Nadi' is derived from the root
'Nad,' which means 'motion.' The critical force or Pranic current passes or
flows through these Nadis (Sukshma, subtle passages). Since they are made up of
subtle matter, they are invisible to the naked eye and cannot be tested in a
test tube on the physical plane. These Yoga Nadis are not the same as the
Vaidya Shastra's muscles, lungs, and veins (Anatomy and Physiology). Yoga Nadis
are not the same as these.
There are so many Nadis in the body that they can't be
counted. The number of Nadis is reported differently by various scholars,
ranging from 72,000 to 3,50,000. When you look at the internal anatomy of the
body, you feel a sense of reverence and wonder. Since the Divine Lord Himself
is the architect, aided by professional builders and masons—Maya, Prakriti,
Visva Karma, and so on.
In this Yoga, the Nadis are extremely important. When Kundalini awakens, it can pass through Sushumna Nadi, which is only possible if the Nadis are pure.
As a result, the purification of Nadis is the first step in
Kundalini Yoga. A thorough understanding of the Nadis and Chakras is needed.
Their position, roles, and composition, among other things, should all be
extensively investigated. Yoga Nadis, or subtle lines, have an impact on the
human body. The human body manifests and operates all of the subtle (Sukshma)
Prana, Nadis, and Chakras. The gross nerves and plexuses are intertwined with
the subtle nerves and plexuses.
This is something you should be aware of. Since the physical centers and the astral centers have such a similar relationship, the vibrations emitted in the physical centers using specified methods have the desired effects in the astral centers. The term "plexus" refers to a center where many nerves, lungs, and veins intertwine. Pampiniform, Cervical, Brachial, Coccygeal, Lumbar, Sacral, Cardiac, Esophageal, Hepatic Pharyngeal, Pulmonary, Ligual Prostatic Plexus, and other physical substance plexuses are known to the Vaidya Shastra. In the Sukshma Nadis, there are plexuses or centers of critical powers. They're called 'Padma' (lotus) or 'Chakras.' Many of these centers have detailed guidelines that can be found elsewhere.
The
Kanda is the source of all Nadis. It is at this point that the Sushumna Nadi
and the Muladhara Chakra meet.
This Kanda is said to be 12 inches higher than the anus. Of
the numerous Nadis, 14 are said to be important. Sushumna, Sushumna, Sushumna,
Sushumna, Su Ida is a character in the film Ida Pingala Pingala Pingala Pingal
Hastajihva Gandhari Saraswati Kuhu Pusha is a character in the film Pusha
Payasvini Sankhini Varuni Alambusha is a character in the film Varuni Alambusha
Yasasvini Vishvodhara Ida, Pingala, and Sushumna are the most important of the
14 Nadis mentioned above, with Sushumna being the chief. It is the Yogins' best
and most coveted prize. This subordinates every such Nadis. The following pages
provide detailed guidance on each Nadi and its purposes, as well as the
procedure for awakening the Kundalini and moving it from Chakra to Chakra.
Since all of the Chakras are bound to the Spinal Column, you must first learn about it before moving on to the study of Nadis and Chakras. Meru Danda is the name given to the spinal column. This is the body's axis, just as Mount Meru is the earth's axis. As a result, the spine is known as Meru. The back is also known as the spine, axis-staff, or vertebral column.
The human being is a microcosm. (Kshudra-Brahmanda - Pinda).
Mountains, seas,
Bhutas, and other objects seen in the world occur in the body as well. The body
contains all of the Tattvas and Lokas (worlds). The body is divided into three
major parts: the head, trunk, and limbs, with the head and legs forming the
body's core. From the first vertebra, the Atlas bone, to the end of the trunk,
the spinal column runs. The spine is made up of 33 bones known as vertebrae,
which are classified into five regions based on their positions:— 7 vertebrae in
the cervical area (neck) 2. 12 vertebrae in the dorsal area (back) 3. 5
vertebrae in the lumbar zone (waist or loins). 5 vertebrae in the sacral area
(buttocks, sacrum, or gluteal). Coccygeal region (number 5) (imperfect
vertebrae Coccyx) There are four vertebrae in all.
The vertebral bones are stacked one on top of the other,
forming a pillar for the cranium and trunk to rest on. Spinous, transverse, and
articular processes, as well as fibro-cartilage pads between the bones, bind
them. The vertebral arches form a hollow cylinder, a bony covering, or a
passageway for the spinal cord. The vertebrae vary in size from one another.
The vertebrae in the cervical region, for example, are smaller than those in
the dorsal region, but the arches are larger. The largest and most important
part of the lumbar vertebrae is the body. The spine as a whole is not rigid,
but has curvatures that lend it a springy feel. This spine connects all of the
other bones in the body.
There are apertures between each pair of vertebrae from
which spinal nerves travel from the spinal cord to various parts and organs of
the body. Muladhara, Svadhishthana, Manipura, Anahata, and Vishuddha are the
five regions of the spine that refer to the five Chakras: Muladhara,
Svadhishthana, Manipura, Anahata, and Vishuddha. Ida is on the left side of the
spine, and Pingala is on the right side. Sushumna Nadi flows into the hollow
cylindrical cavity of the vertebral column.
SUKSHMA SARIRA
The human form takes on the characteristics of the astral
body. Sthula form's outer body is similar to water. The astral body is
represented by the steam or vapour generated when water is heated. The astral
or Sukshma body is also included within the gross or actual body. Without the
astral body, the gross body is powerless. Any physical center of the body has
an astral counterpart. Since this Yoga deals with the center of the astral
body, a thorough understanding of the gross body is essential. As a result, in
the following pages, you'll find a brief overview of the gross body's centers
and their Sukshma Sarira counterparts. In the human body, you'll find examples
of the astral centers and their associated functions.
KANDA
Between the anus and the base of the reproductory gland,
this is located. It has the appearance of an egg and is surrounded by
membranes. This chakra is located directly above the Muladhara Chakra. This
Kanda is the source of all the body's Nadis. It is at this point that Sushumna
and Muladhara Chakra come together. On the sides of this Kanda are the four
petals of the Muladhara Chakra, and the intersection is known as
Granthi-Sthana, where Maya has a heavy influence. Kanda is 9 digits above the
anus, according to some Upanishads. Kanda is the astral body's core, from which
Yoga Nadis, or subtle pathways, emerge and bring Sukshma Prana (vital energy)
to all areas of the body. The gross physical body has a ‘Cauda equina' that
corresponds to this core. From the hippocampus to the end of the vertebral
spine, the spinal cord tapers off into a fine silken ribbon. It emits a large
number of fibres before terminating, which are clumped together into a cluster
of nerves. In the gross body, this group of nerves is known as the ‘Cauda
equina.' Kanda is the astral core of the Cauda Equina.
The hippocampus and spinal cord, also known as the
cerebro-spinal axis, make up the central nervous system. The Bulb, or
continuation of the Medulla oblongata, serves as a connection between the brain
and the spinal cord. The involuntary processes of breathing and swallowing are
closely linked to the Medulla oblongata's middle. From the tip of the spinal
canal to the second vertebra of the coccygeal zone, the spinal cord tapers off
into a fine silken thread known as Filum terminale. The spinal cord is a column
of grey and white brain matter that is very soft. On the sides of the grey
matter, the white matter is arranged.
The gray matter is made up of brain cells and fibers, while
the white matter is made up of medullated nerves. This is not closely fitted
with the spinal canal, but rather suspended or lowered into the spinal canal,
similar to how the brain is suspended in the cranial cavity. The membranes
provide nourishment for this. In the cerebro-spinal fluid, the brain and spinal
cord float. As a result, the fluid protects them from any damage. A fatty
tissue lining protects the spinal cord as well. An anterior and posterior
fissure divides it into two symmetrical halves.
A small canal called canalis centralis runs through the
heart of the city. From Muladhara to Sahasrara Chakra, the Brahmanadi flows
along this canal. Kundalini, when awakened, passes through this Nadi and
through Brahmarandhra. The brain and spinal cord are not isolated or split. It
is linked to the brain in a continuous manner. This cord connects both of the
cranial and spinal nerves. This is linked to every nerve in the body. This
spinal cord controls the organs of reproduction, micturition, metabolism, blood
supply, and respiration. The medulla oblongata connects the spinal cord to the
brain's fourth ventricle. It extends from the fourth ventricle of the brain to
the third, then the fifth, and eventually the crown of the head, the Sahasrara
Chakra.
SUSHUMNA NADI
When we examine the structure, place, and role of the Spinal
Cord and the Sushumna Nadi, we can easily conclude that the Spinal Cord was
once known as the Sushumna Nadi. The gross form and functions of the Spinal
Cord was dealt with by Western Anatomy, while the Yogins of ancient times dealt
with the subtle (Sukshma) existence. You should now have a detailed
understanding of this Nadi in Kundalini Yoga. Sushumna stretches from Muladhara
Chakra (second coccygeal vertebra) to Brahmarandhra. The Spinal Cord has a
central canal called Canalis Centralis, and the cord is made up of grey and
white brain matter, according to Western Anatomy.

with the subtle (Sukshma) existence. You should now have a detailed
understanding of this Nadi in Kundalini Yoga. Sushumna stretches from Muladhara
Chakra (second coccygeal vertebra) to Brahmarandhra.
The Spinal Cord has a central canal called Canalis
Centralis, and the cord is made up of grey and white brain matter, according to
Western Anatomy. In the cavity of the spinal column, the spinal cord is fallen
or suspended. Sushumna is similarly placed inside the spinal canal and has
subtle portions. It has the same red color as Agni (fire). There is a Nadi
named Vajra inside this Sushumna that is as lustrous as Surya (sun) and has
Rajasic qualities. Another Nadi, called Chitra, exists inside the Vajra Nadi.
It has a Sattvic nature and is light in color. The three aspects of Sabda
Brahman are Agni, Surya, and Chandra (fire, sun, and moon). There is a very
good minute canal here inside this Chitra (which is known as Canalis
Centralis). When Kundalini is awoken, it travels from Muladhara to Sahasrara
Chakra through this canal, which is known as Brahmanadi. All six Chakras are
present in this middle (lotuses, viz., Muladhara, Svadhishthana, Manipura,
Anahata, Vishuddha and Ajna).
Since Kundalini must pass through this door to reach
Brahmarandhra, the lower extremity of the Chitra Nadi is known as Brahmadvara,
the door of Brahman. In the macrocosm, this corresponds to Haridwar, which is
the gate of Hari of Badrinarayan (physical plane). In the Cerebellum, the
Chitra comes to an end. The Sushumna Nadi (gross Spinal Cord) is called Brahma
Nadi in general since Brahma Nadi is located inside the Sushumna. Since the
river is inside the Sushumna, the canal within the Chitra is also known as
Sushumna. On the left and right sides of the spine, Ida and Pingala Nadis are
located. Chitra is the most powerful and well-liked of the Yogins.
It looks like a lotus cord. It is located in the heart of
Sushumna and is brilliant with five colors. It is the most important organ of
the body. This is referred to as the Heavenly path. It is the one that bestows
immortality. The Yogi destroys all sins and attains the Highest Bliss by
imagining the Chakras that reside in this Nadi. It is the one who bestows
Moksha. The mind becomes steady as the air runs through Sushumna. The highest
state of Yoga is known as "Unmani Avastha," or mental stability. You
would have wonderful meditation if you sit for meditation while Sushumna is
around. The breath cannot flow through the middle Nadi because the Nadis are
clogged with impurities. As a result, Pranayama should be used to purify the
Nadis.
SYSTEMS OF PARA-SYMPATHETIC AND SYMPATHETIC
The sympathetic and para-sympathetic cords, a double chain
of ganglia, run to each side of the spinal cord. A ganglia is a group of nerve
cells. The Autonomic System is made up of nerves that supply and regulate
involuntary organs like the heart, lungs, intestines, kidneys, and liver. The
sympathetic system produces the vagus nerve, which is important in human
economics. The sympathetic nervous system activates or speeds up. The
parasympathetic nervous system slows or stops. Nerves dilate or widen the
arteries, which contain pure oxygenated blood to nourish the muscles, lungs,
and cells of the body's various components. Vaso-dilators are what they're
called. Filaments bind the sympathetic links on the left and right sides. These
cross from right to left and vice versa, but the precise locations of these
crosses are unknown, despite many attempts to locate them. “Where the sensory
fibres migrate from one side to the other is not known,” M'Kendrick and
Snodgrass write in Physiology of the Senses. “In certain areas of the spinal
cord, sensory fibres do cross from the right to the left side and vice versa.”
PINGALA NADIS AND IDA
The gross compassionate chains are not Ida and Pingala
Nadis. The Sukshma Prana is carried by these slight Nadis. Both roughly equate
to the right and left sympathetic chains of the human body. Ida begins with the
right testicle and Pingala with the left. They meet at the Muladhara Chakra and
tie a knot with Sushumna Nadi. Mukta Triveni is the name given to the
intersection of three Nadis at the Muladhara Chakra. Pingala, Ida, and Sushumna
Nadis are home to the Ganga, Yamuna, and Sarasvati, respectively. Brahma Granthi
is the name of the meeting spot. These come together again at the Anahata and
Ajna Chakras. In the macrocosm, the three rivers Ganga, Yamuna, and Sarasvati
converge at Prayag, forming a Triveni. Ida and Pingala circulate from the left
and right nostrils, respectively. Ida is also known as Chandra Nadi (Moon), and
Pingala is known as Surya Nadi (Sun) (sun). Pingala is heating and Ida is
cooling. The food is digested by Pingala. Sakti Rupa, Ida is pale. It is the
world's great nourisher. Rudra Rupa's Pingala is a flaming red. Sushumna
swallows time, while Ida and Pingala suggest Kala (time). The Yogi knows when
he will die; he enters Sushumna, holds his Prana in Brahmarandra, and defies
time (Kala—death). By bringing the Prana into Sushumna, Maharashtra's famed
Yogi Sri Chang Dev battled death many times. Sri Jnanadev of Alandi, near
Poona, was his contemporary. Via his Yogic rituals, he achieved Bhuta Siddhi,
or dominance over wild animals. He came to see Sri Jnanadev on the back of a
tiger.
