The excitement of all the Chakras, mentioned above takes place always through Kundalini. It is the lever of consciousness by which the individual realises his onesness with the Absolute. The creative impetus, which emanates from the divine, is communicated through Kundalini, the serpent power as it is called, to the six chakras or plexuses and their connection. Normally, Kundalini is sleeping a trance-sleep (Yoga-nidra), and when it is awakened from this slumber and made to work, the Yogi perceives all supernatural truths. The resurrection of the soul from the grave of untruth becomes an actual fact, and perception of beauty, which is an attribute of the Self, fills the heart with joy. Health is also said to be the gift of Kundalini; Kundalini is the mother of joy, of sweet rest, of sleep, of faith and of wisdom. Kundalini is the queen and guide of lives that breathe, i.e., of all vertebrate animals. What is this of a Yogi and to which is a prime-mover of the practice of a Yogi and to which such wonderful powers have been attributed ? Kundalini has long remained a mystery. In the following pages I propose to attempt an explanation of this mystery in terms of modern science.
Swami Vivekanand, in his book Raja Yoga, defines Kundalini as follows : “The centre where all residual sensation are, as it were, stored up is called Muladhara-chakra, and the coiled up energy of actions is Kundalini, the coiled up.â€
Arthur Avalon in his book, The Serpent Power, states that “Kundalini is the Static Shakti.†He says further : “It is the individual bodily representative of the great cosmic Powers (Shakti) which creates and sustains the universe â€; and in support of his statement he gives at the end of the book the scientific and masterly exposition of this Shakti, composed by his friend Prof. P. Mukhopadhyaya. All the explanations about this Shakti, though learned, could as well as be applied to the autonomic nervous system. The static or anabolic power is the para-sympathetic portion of it, and the Dynamic or Katabolic power is the sympathetic portion. Some have suggested that Kundalini is the inferior Venacava, while others conjecture it to be the large bowels. On what basis these conclusions have been arrived at, I am unable to conceive.
According to Hata-Yoga-Pradipika, the Kundalini is said to be lying dormant guarding the opening of the passage that leads to the seat of Brahma. This seat is said to be Brahma-randhra, that is, the ventricular cavity in the brain. The passage to that cavity, in my opinion, is the narrow space at the lower end of the fourth ventricle in the brain, which communicates the ventricles of the brain with the channel in the spinal cord (Sushumna nadi) and the subarachnoid space (Akasha). The dormant Kundalini thus guards the three important openings in the cerebro-spinal nervous system. Unless she is awakened, or made consciously active, one cannot send one’s embodied soul (jivatma), which is supposed to reside in the heart (Hridaya), along the Sushumna nadi to the Brahma-randhra nor is he able to assist the soul captured in the Randhra, to be freed to join the Universal Soul (Paramatma) outside.
Likewise the Kundalini is said to be sleeping above the Kanda; and the shape of the Kundalini between these points has been described as being like a serpent. To understand the exact extent of this Kundalini we must determine the position of the Kanda in the body. Different authors have given slightly different locations of this Kanda but they all agree that it is placed in the lower part of the body but above the anus, and that its size is about four angulis, i.e., about three inches in the length, and an equal number of inches in breadth; that it has the shape of a leaf or triangle, or that of a bird’s egg, broad above and narrow below, and that it is covered with a soft, flimsy, plaited, white cloth.
According to Goraksha-shataka the situation of the Kanda is on a level with a point between the umbilicus and the penis. That point corresponds to the upper border of the triangular piece of bone at the lower end of the spinal column which is wedged in between the two hip bones and is known as the sacrum, the upper border of its front surface is known as the promontory of the sacrum.
By Yanya-Valkala, the Kanda is located about nine angulis, i.e., six inches above the mid-point of the body and extends about four angulis in length and width. The mid-portion of the body is said to be the space which is two angulis (a little over an inch) above the anus, and an equal number of angulis below the root of the penis. This space, according to our knowledge of anatomy, corresponds with the Coccyx, the lowest bone of the spinal column. A distance of nine angulis above this space corresponds with the promontory of the sacrum. In Hatha-Yoga-Pradipika, the origin of Kanda is given as twelve angulis, i.e., nine inches above the raphe of the perineum and that too corresponds with the promontory of the sacrum.
Though the different manuals on Yoga describe the location of Kanda in different terms, they agree as to its root being a point between the navel and the external genitals.
This Kanda is also called Mula-Kanda or Muladhara, that is root-bulb or root-support, probably of the Meru-danda. This Muladhara is said to be the receptacle of a plexus or a Chakra called Muladhara-chakra; it is also said to form the backward limit of the Yoni (perineum). The soft white plaited cloth with which it is said to covered is, I believe, well represented by pelvic fascia with its folds which lines the internal surface of the sacrum (Kanda).
Kanda, thus, could be identified with the sacrum, though it is translated to denote ‘ganglia’ in some of the Marathi and English books on Yoga. Kundalini at the site of its origin, which is above the promontory of the sacrum, is said to be lying dormant in the shape of a serpent coiled up. Lower down it joins the Muladhara-chakra which is at the end of the Kanda (the sacrum). Higher up, it passes through the different chakras and meets the brain through an opening in the Talu (the base of the skull). A fuller account of these chakras will be given presently.
In the Tantril Manual, Shat-Chakra-Nirupanam, it is said that the pericarp of the Adhara lotus is a triangle or Kanda mentioned in the Hatha-Yoga-Pardipika. Inside this triangle there is a linga or phallus called Swayambhu, which tapers like a new unopened leaf-bud. This description of the phallus well applies to the lower end of the spinal-cord with its dural sheath, which ends in the canal of the sacrum (Kanda) blindly in a cul-de-sac at the level of the second sacral vertebra. This phallus extends a little beyond the triangle. Above it, on a level with the lower end of the spinal canal (Chitra), the Kundalini is said to be sleeping, closing the mouth of the Bragmadwara. This position of the sleeping Kundalini is about the same as the position of the lower end of the dormant Kundalini mentioned in the Pradipika.
It appears from the description and position of the dormant Kundalini that it must be a prevertebral plexus of the autonomic nervous system, and that plexus I take to be the Solar plexus of the sympathetic which lies on the vertebral column on a level with the first and second lumbar vertebrae, where the lower end of the spinal-cord, called the Conus-medullaris, with its canal comes to an end. Extending from this sleeping Kundalini, otherwise called Kula-Kundalini, a fibre is described which descends and shines like a chain of brilliant lights in the cavity of Mula-lotus. From the skirts of this dormant Kula-Kundalini there starts another Kundalini, which ascends along the Sushumna nadi and reaches, as said elsewhere, to a point (Bindu or Para Shiva), which is bathed in the stream of the ambrosia (Cerebro-spinal-fluid) from the Eternal Bliss (Brahma-randhra), and illuminates even the lowermost cavity of this bodily universe by her radiance.
It will thus be seen that Kundalini extends from the brain to the Muladhara-chakra and is divided into two parts by the Kula-Kundalini which rests on the lower end of the spinal canal Brahma-dwara or the gate of Brahma.
Whether the Brahma-dwara should be taken to mean the lowermost ends of the spinal canal, or its uppermost end where it joins the Brahma-randhra or whether it should be taken to mean the whole of the spinal-cord, by which the Kundalini as a conscious force is made to ascend to the Sahasrar, is decided by the description given in the Shat-Chakra-Nirupanam, where it is said that the Kundalini in the lower gateway of Brahma is in a sleeping or inert state and at the upper gateway of Brahma it resides, in an active state capable of being stimulated. Thus these two points, the upper and lower gateways of Brahma, define the limits of the Kundalini or the Parameshwari of lives that breathe.
When this Kula-Kundalini is awakened or made active, it forces a passage through the different Chakras and excites them to action, and, as it rises step by step, the mind becomes opened and all visions and wonderful powers come to a Yogi, when it reaches the brain. The Yogi then is perfectly detached from the body and the mind, and the soul finds itself free in all respects.
Kundalini then joins her lord Para-Shiva (the olivary body) who has the form of a dot “O†(Bindu-rupa) and is situated in the Itata-linga (medulla oblongata) which has as its perticarp cerebrum (Brahma-chakra). Kundalini thus connects herself with Brahma-randhra, a cavity in the brain, where the Brahma or the Soul, is located, and the knowledge of which the Yogi seeks to attain. It is this cavity which is guarded by six doors, and Kundalini is the only force that can open them. It is this cavity, where Prana centres all its activities; it is here where the soul is carried to reside; it is here that the unruly Chitta, the mind-stuff, is captured and made steady by the process of Pranayama; it is here that the Chitta is submerged in Prana, this submersion bringing all the activities of the mind and Prana to a standstill. The soul, thus made free from the thralldom of the intellect, feels its own joy and sees itself “So’ ham†i.e., “I am That†or “I am He,†literally “That am I.†It is only when the mind and the Prana act as two conflicting entities that they run riot and keep the soul in the bondage of the Maya, the surrounding objects of the senses. Though the soul is freed from the shackles of Prana and Chitta, it is still made to remain there by the current of Vasana, which is guarding the orifice of this cavity in the form of Kundalini,, the cord of desire. These desires revert the soul to the control of Prana and Chitta (the mind-stuff), and successive rebirths are the result. This anything but what the Yogi desires; he wants to escape this, which can only be done by tearing asunder the cords of desire by bringing Kundalini under control. When Kundalini is made to obey the callings of the soul, the soul escapes from this cavity to occupy another cavity called Akasha, which surrounds the brain and the spinal-cord. Further the soul, freed from the control of Prana, Chitta and Vasana, lives outside the Brahma-chakra, the cerebrum, and is said to pervade the whole universe. When the Yogi attains this state, he is said to be in the Nirvikalpa Samadhi, seedless Samadhi by which he gets in tune with the Infinite and escapes rebirths.
A question may be asked as to what we are to understand by the term Vasana which leads an individual to successive rebirths. To know the proper meaning of the term, according to Indian Philosophy, we shall have to deal with Karma of the embodied soul, the Jivatma of a being. Karma of an individual is comprised of desire (Vasana) start a current of thought, which is conveyed to the Jivatma and is then translated, through his agency, into actions, good or bad ones to misery. Karma is of three kinds. Sanchita Karma, the outcome of Sanskara (impressions of past lives) and desires (Vasana), is all the accumulated and unexhausted Karma of past lives with which is still to bear fruit. Prarabdha Karma is that part of the Sanchita Karma which is worked out and the result of which is made known to us in our present birth. Kriyamana Karma, either Vartaman or Agami, is that which a man is continuously hoarding up by his present and future actions. It will thus be seen that the vicious circle of Vasana, by continuously forming a web around the soul, forces it to remain embodied for liberating and experiencing the past Karma. Its final emancipation then could only be achieved by putting a stop to generation of new Karma by conquering our Vasana or desires. When this is done there is nothing left to generate new Karma, and the Jivatma is liberated from successive births. On the physical plane, this can only be done by controlling the cord of desire, the Vagus nerve (Kundalini), by consciously controlling all the involuntary action of the body, which are in some sense or other under the control of the Vagus nerve. By submersion of the voluntary and involuntary actions of the body into Chitta and Vasana all the functions of the body are brought to a state of automatism. Finally, the embodied soul (jivatma), freed from the activities of the body, merges into the Supreme Soul (Paramatma) outside the body and gains its final emancipation, i.e., liberation from re-birth.
All the writers on Yoga have translated Randhra as a ‘hole.’ It could as well be translated as a ‘cavity’ (Apte’s Sanskrit Dictionary), and I would rather put that second interpretation on the word “Randhra†as it is more in keeping with our knowledge of Western Anatomy. This cavity is surrounded by a chakra or plexus of a thousand branches, known as Sahasrara or Brahma-chakra, the cerebrum. Here the word thousand should not be translated too literally. It is there to convey the idea of innumerableness. This Randhra is the inter-communicating cavity of the four ventricles of the brain and is continuous with the central canal (Chitra) of the spinal cord (Sushumna nadi). This cavity is constantly secreting a fluid called the Nectar of Life or the divine fluid, the cerebro-spinal fluid. At the end of this cavity is an orifice which connects the internal cavity of Prana with the external cavity of Akasha surrounding the brain and the spinal cord and known as the sub-arach-noid space, and is bathed with the divine fluid which is secreted by Brahma-randhra.
