The word nadi comes from the Sanskrit root nad meaning "channel", "stream", or "flow."
Nadis are thought to carry a life force energy known as prana in Sanskrit, or qi in Chinese-based systems. In particular prana (active) is supposed to circulate inside Pingala, while apana (passive) is supposed to circulate inside Ida. Inside Sushumna is supposed to circulate kundalini when awakened.
The nadis is symbolized in the cadeceus, which became the symbol of the medical profession. The three main channels (nadis)- Ida, Pingala and Shushumna (sympathetic, parasympathetic, and central nervous system) - run along the spinal column from the root center in a curved path & cross one another several times.
At the intersection points are strong energy centers called chakras. The two nadis are believed to be stimulated through different practices, including Pranayama, which involves alternate breathing through left and right nostrils, which would alternately stimulate respectively the left and right sides of the brain.
The Ida and Pingala nadis are often seen as referring to the two hemispheres of the brain. Pingala is the extroverted (Active), solar nadi, and corresponds to the right hand side of the body and the left hand side of the brain. Ida is the introverted, lunar nadi, and corresponds to the left hand side of the body and the right hand side of the brain (crossing occurs in the optical chiasma). These nadis are also said to have an extrasensory function, playing a part in empathic and instinctive responses. (http://en.wikipedia.org/wiki/Nadi_(yoga).html) \
The 7 Major Chakras
Root (Muladhara) – Survival. It stores our core identity. It opens to oneself and is the foundation of core beliefs; alter-ego – Brow to Crown; access potentials; New Age Ray link to higher rays; last to be aroused
Sacral (Svadisthana) - Creativity and Sexuality. It opens the records of beliefs and experiences; controls sex life. It is transmuted to throat center.
Solar Plexus (Manipura) – Perceptual. Gut Feel, which intuit our way through life; motivates the heart; balances and harmonizes the emotional and mental bodies. It pertains to perseverence and the deva evolution. Involves the transmutation to the heart center.
Heart (Anahata) - Center of compassion & link to all; flow of compassion goes beyond judgment (the trap)
Throat (Visshuddha) – Speech, through which we speak our truth
Brow (Ajna) – Third Eye. Ability to see beyond the 3rd Dimension; motivates integration; service, forgiveness. It stimulates intuition, hearing and seeing. It involves the shift from the Sacral to Crown center.
Crown (Sahasrara) – Knowing. When opened, connects and circulates spiritual energies. Once stimulated, the pineal, pituitary and hyphothalamus actively link you up.
The Endocrine System
The Chakras are linked to specific Endocrine Glands in the physical body; the glands are the physical manifestations of the chakras. The Endocrine glands act as transducer of energy that changes energy from one form to another (Cayce). They operate to change psychic and mental energy patterns into physical patterns within the body and vice-versa. The Table shows the correspondents with the first 7 chakras.
1. Pineal & Hypo-thalamus Glands (Crown)
Produces melatonin which regulates sleep and waking up. Light stimulation of the Pineal affects the Leyden’s production of sex hormones. Connects the inner vision of imagery with the creative principle. The Hypothalamus regulates body temperature and water. It is the gatekeeper between the physical body and the outer chakras. When stimulated, it leads into a new domain chemically induced without taking anything. (Note: some say that the pineal and pituitary should be exchanged in their relationship to the Crown and Brow chakras. Leadbeater associated the Anja with the pineal)
2. The Pituitary (Brow or Ajna Center)
Like the Pineal, is basically dormant (Marciniak). In Cayce, the Pituitary is the 7th center. Its hormones communicate to the rest of the glands and connect to the central nervous system via the Hypothalamus. The Thalamus has a key role in the physical basis of consciousness. Ajna's key issues involve balancing the higher & lower selves and trusting inner guidance; the inner aspect relates to intuition; mentally, with visual consciousness; emotionally, with clarity on an intuitive level.
3. Thyroid (Throat)
4. Thymus (Heart Center or Anahata)
Part of the immune system; the T cells produced fend off disease; may be affected by stress. Sends signals for rejuvination. The gatekeeper that regulates what comes from above and from below the neck. It shinks the older one gets. It is not continuously giving signals of its idealized blueprint because it is not getting the messages from the temples of the head; they were severed from the full strand of DNA. When the body & mind is ready (for life expansion), the thymus returns to vitality. Key issues involve complex emotions, compassion, tenderness, unconditional love, equilibrium, rejection and well-being; physically, circulation; emotionally, unconditional love for self & others; mentally, passion; and spiritually, devotion.
5 Pancreas Adrenals; “Guts” (Solar Plexus or Manipura)
Seat of power in the body. Through the feeling center (inner wisdom), you feel your way through events that may make no sense logically. (in Cayce, the Adrenals activate mediumship; serves as broadcaster, amplifying the exchange of signals among the other glands; center for “flight or fight”). The Solar Plexus is believed to correspond to the Islets of Langerhans, cells in the pancreas, and the outer adrenal glands and adrenal cortex. They play a valuable role in digestion. Key issues governed by Manipura are of personal power, fear, anxiety, opinion-formation, introversion, and transition from simple or base emotions to complex; mentally, personal power; emotionally, expansiveness; and spiritually, all matters of growth.
6. The Cells of Leydig (Polarity or Sacral): The “seat of the soul.”
The soul’s companion is the subconscious mind. These two abide in the autonomic nervous system and directly affect the glands and the hormones. Their primary points of contact are the 2nd and 6th chakras. The Sacral (Svadisthana) corresponds to the testes or the ovaries that produce the various sex hormones involved in the reproductive cycle. It is also considered to be related to, more generally, the genitourinary system and the adrenals. The key issues involving Svadisthana are relationships, violence, addictions, basic emotional needs, and pleasure. Physically, Svadisthana governs reproduction, mentally it governs creativity, emotionally it governs joy, and spiritually it governs enthusiasm.
7. Gonads- Ovaries and Testes (Root)
Descent from heaven into matter in this world, with outer influences taking hold and possesing us. This chakra is where the 3 channels are merged, then separate and begin their upward movement. Inside of this chakra is wrapped up the kundalini three times around a black lingam. Although no endocrine organ is placed here, it is said to relate to the gonads. There is a muscle located in this region that controls ejaculation in the sexual act of the human male.
With the Harmonic Convergence in August 1987, the opening of the higher centers (8-12th) outside the body were made available, linking the human being to the centers of the Earth, the Solar System and the Galactic Core . The Higher Centers are also called Jacob's Ladder.
The 8-12 centers are presented in the Table. The 12 chakras, when developed, are spinning centers of information or light encoded filaments (etheric discs). (From Barbara Marciniak - Pleiadians)
The Soul Star or Alta Major Chakra – Located 12 inches or more above the body, this chackra relates to the invisible realm outside the body. It cleanses and heals the four lower bodies and brings clarity to daily experience. It stimulates the ajna opening and cleanses the subconscious. The 8th chakra is the last of the "human" chakras which hold us prisoner in this manifest world. Clearing patterns held in this chakra will free our being and allow the development and understanding of our true spiritual identity.
Earth Chackra – Located within a few feet above the head. (After nine helixes are formed) it will move out of the atmosphere. It may go as far as the moon, linking you as a steward and watcher of earth. It activates the thymus and integrates the heart, thymus, and throat into the Solar Power Center. It also aids in soul merge, the 3rd initiation, and contact with our Christed (body of light).
Solar Chakra - Onced aligned and plugged in, will be aligned to solar system. It assist in building our light body and align with the chakras below our feet.
Galactic Chakra - Chakra hooked up from the palm and is plugged into the “Galactic system.” It provides the link and information to our local stellar influence. It is the rainbow bridge to New Age, the higher dimensions, the I Am and Mother Earth. It balances humanity.
Univeral Chackra - Hooked up from the palm to the “Center of Universe,” outside Galaxy (the rest of the universe as pictured); Illumination; God source; contain all the Rays; help integrate all qualities; color of higher beings. The opening began early 1990s.
