Everything stops at the peak of the elecrtical stimulation. Then, the soul gets absorbed quickly back in the chest, diving into an infinite abyss. One could feel the heart explode. A void fills the mind. It’s pitch black but so clear. Hovering over the horizon is a thin white line. The sound of the OM emerges, vibrating and humming.
— Fyodor, on Samadhi
Subtle sounds, vibrations, music and chimes which can be heard in and around the cranial cavity are common signs of kundalini. Profound ones such as voices, intuitive signals, visions and energy figures as well as radiance are experienced from the deeper levels of consciousness.
These manifestations are difficult to explain at intellectual, logical and scientific levels. For example, nada is a sound but it is not a physical sound. The ringing bell and music are familiar ones but they come from nowhere close but inside the brain. This is a higher state. Ultimately the subtle sounds become pure vibration, pulsating constantly and sometimes rhythmically. Exploring the nada is an interesting journey. The deeper you go, the more you come into contact with the cosmic mind.
Unmade sounds are all over. They manifest randomly. These sounds are fleeting making it difficult to trace and sustain clearly. Most ones we experienced are those which come from the brain. For someone whose kundalini is aroused properly, these sounds are ordinary. Meditating upon the nada could powerfully absorb the mind, leading to samadhi.
In samadhi, the soul emerges. The spirit comes more clearly than what your external senses can perceive. Not only can you hear the bell and the angels singing, but you can also hear instructions (voices) and see the future. It is no rare we hear stories of revelation. They have a basis for it is the cosmic force appearing. If properly channelled and initiated, such a gift could be utilised to treat and heal the sick and end one’s suffering.
Hatha Yoga: Mudras and The Nada
The mudras (and bandhas) are practised to stimulate the Central Nervous System (CNS) in preparation for meditation. Of all the mudras in hatha yoga, the khechari mudra is the most powerful in magnetising the spinal cord (sushumna nadi) and the inner brain (ajna chakra). However, khechari mudra requires many years of practice and preparation. Also, it is ideally learnt directly from the guru because the student would have to accomplish various preparatory observances first before learning the khechari mudra.
When the spinal cord can freely transmit the energy to the brain, the student attains the state of parichaya avastha or ‘the state of increase’. In this state, the kundalini energy freely pierces through the chakras of the astral system and shall enter the brain (through the spinal cord). This result in the intense electrification of the brain, thus ‘the state of increase’.
The three fundamental nadis, namely ida (left), pingala (right) and sushumna (centre) bind again in the ajna chakra. The text Shiva Samhita states this about this deep spiritual union: “The vayu (prana, life-force) does not move through the moon and sun (ida and pingala) but remains steady in sushumna. This takes place when one has control of kriya shakti or pingala and has pierced the six chakras.” (3:60, 61)
How To Chant the OM?
Parichaya is the realm of deep sound vibrations. In this third stage, the sound of the drums (OM) appears. One gets absorbed in this great void inside the chest. Life stops here and one enters the place of total perfection or siddhi.
Hatha Yoga Pradipika Chapter 4 verse 74
Hatha Yoga prescribes predominantly pranayama and mudras to attain the state of parichaya. The Shiva Samhita states aside from pranayama and mudras, the student should also practice the Om mantra (pranaya) for the completion of their spiritual awakening. It states that by chanting the Om, “the yogi (should) destroy(s) his karma so that he need not be reborn.”
You can chant the OM after your physical and energetic practices. Then, meditate in stillness and silence. The ideal asana for the OM mantra is the siddhasana for males and siddha yoni asana for females. Siddhasana directly stimulates the spinal cord, making the technique more potent and confined. Alternative to siddhasana is sukhasana (happy posture) and ardha padmasana (half lotus).
To start the practice, take a deep relaxing inhalation. Do not strain. For the sound to come out fluidly, the mind should remain calm. Then, chant the OM, fluidly, let the sound start from the front of the mouth (feel the vibration touch the hard plate then, the base of the brain). Slowly round the lips and dome and the back of the nasal cavity and channel the sound vibration to the midbrain. Slowly close the lips and vibrate the frontal brain. You will feel the entire brain vibrate as you hum the consonant M….
Distribute the sound vibration evenly to the base, interior and surface of the brain. This powerfully amplifies the alpha and theta brain frequencies which are responsible for absorbing the mind.
