The Anatomy of the mahākāla bīja : 'hsaumh' (ह्सौम् / ह्सौंः)

1. The Anatomy of the mahākāla bīja: 'hsaūṁḥ' (ह्सौंः)

In strict accordance with the mantra śāstra dictionaries the composition of this specialized prāsādaparā variation reveals a profound union of śiva, śakti, prāṇa, and ultimate dissolution:

ह (ha) + स (sa) + औ (au) + ं (ṁ) + ः (ḥ) = hsaūṁḥ

(The macron over the 'u' in ūṁ is traditionally used in tantric scription to indicate the prolonged vocalization/plavanam of the vowel prior to the bindu). 

• ha-kāra (ह): represents the śiva tattvam (prakāśa – Pure, static Consciousness).
• sa-kāra (स): represents the śakti tattvam (vimarśa – Cosmic energy and kinetic manifestation).
  Together, ha and sa constitute the foundation of the haṁsa (हंस) tattvam, symbolizing the indivisible unity of śiva and śakti. The ha-sa sequencing establishes the Prāsādapāra direction of cosmic absorption.
• au-kāra (औ): in both sanskrit grammar and tantra, au is a vṛddhi sandhi (an elongated junction of vowels). It acts as the divine knot or cosmic bridge that fuses śiva and śakti seamlessly.  
• ṁ (ं - bindu) and ḥ (ः - visarga): the simultaneous presence of both bindu and visarga represents the ultimate paradox of absolute reality—the supreme concentration of cosmic potential (bindu) alongside the externalized power of projection and ultimate withdrawal (visarga).

Thus, the au-kāra, bindu, and visarga act as the supreme spiritual binding agents, capturing the distinct entities of śiva (ha) and śakti (sa) and locking them into a single, high-vibrational syllable of the Absolute.

2. How 'hsaūṁḥ' Represents the mahākāla and śava rūpa tattvam

The concept of mahākāla denotes a state beyond time—a perfectly motionless, non-dual expanse of Pure Consciousness that remains after the dissolution of the universe. In tantra, this is visually and philosophically termed śava rūpa (the motionless, corpse-like state of śiva). The hsaūṁḥ bīja encapsulates this through four profound secrets:

A. The Inversion and Dissolution of Time

In the natural, living state of a being, the breath moves automatically as an involuntary repetition of the ajapā mantra:

• hakāreṇa bahiryāti: the breath flows outward with the sound of 'ha' (prakāśa).
• sakāreṇa viśet punaḥ: the breath flows inward with the sound of 'sa' (vimarśa).

This continuous cycle of ha-sa (haṁsa) represents the passage of time (kāla) and lifespan.
However, in the mahākāla bīja, this sequence is intentionally inverted into h-sa (ह्स). The movement is arrested; the outgoing life-force (ha) is immediately met with an unmoving wall (sa), breaking the wheel of breath. The cycle stalls, time stands still, and the consciousness lapses into the timeless state of mahākāla.

B. The Code of śava rūpa (The Corpse State)

Grammatically, in the cluster h-sa (ह्स), two consonants (ह + स) collide directly without any intervening vowel.
In tantric phonetics, vowels (svaras) are prāṇa (the life-force/śakti), while consonants (vyañjanas) are physical matter (the body/śiva).
When two consonants are fused rigidly without a vowel (a) to breathe life into them, it structurally represents a state devoid of prāṇic movement. This structural collapse of life-breath into absolute stillness is the literal phonetic manifestation of śava rūpa—the state where śakti's outward dance has dissolved back into śiva's unmoving core.

C. The au-kāra: The Fire of Great Dissolution

In Sanskrit grammar and Tantric phonetics, au is a vṛddhi sandhi—an elongated junction born from the sequential fusion of basic vowels (a + u = o, and a + o = au).

In Mantra Śāstra, au carries immense metaphysical weight:

Directly atop this unmoving, timeless h-sa foundation sits the au-kāra (औ). In the lexicon of tantra, au-kāra is designated as mahāsaṁhāra agni—the cosmic fire of ultimate annihilation. It represents the cataclysmic fire that burns away time, space, causality, and all names and forms.

D. Bindu and Visarga: Absolute Peace

Once the fire of au-kāra swallows the entire cosmic manifestation, what remains is symbolized by the final bindu (ं) and visarga (ः). It is the perfect residue of pure, untainted, unmoving, and utterly peaceful Supreme Consciousness (paramaśiva), holding both the non-dual point of rest and the potential for a new cosmic dawn.

The Divine Synthesis

The functional purpose of the au-kāra, bindu, and visarga is to act as a cosmic vice. They take the independently existing principles of ha-kāra (Śiva) and sa-kāra (Śakti), bind them tightly so their individual motions cease. It anchors the polarities into a single, immutable, atomic syllable.

Summary of the Philosophy - The Resolution into Mahākāla and Śava Rūpa

While haṁsa (हंस) represents the vibration of the living soul (jīva) bound by time, the inverted consonant cluster hsa (ह्स) represents the precise moment the life-force dissolves into mahāsamādhi  

By removing the life-giving vowels (svaras / prāṇa) from between the consonants (vyanjanas / matter), the lifeforce is intentionally arrested. The outgoing breath (ha) is locked flush against the incoming wall (sa).

This absolute cessation of movement is the phonetic evocation of the śava rūpa—the corpse-like, static state of Śiva. When this unmoving foundation is synthesized with the mahāsaṃhāra agni of au and resolved into the quietude of the bindu and visarga, the relative flow of time is completely swallowed. What remains is the immortal, timeless expanse of the mahākāla tattva.

The hsaūṁḥ bīja stands as the ultimate phonetic map of the timeless, motionless, and immortal mahākāla tattvam

THE CONCEPT OF MANTRAS - I

vAgarthAviva saMpRktau vAgartha pratipattaye |

jagadaH pitarau vande pArvatIparameshvarau ||

Thus begins kAlidAsa his raghuvamshamahAkAvya !  Here the great poet addresses the divine couple, the divyadaMpati as ‘jagadaH pitarau’ – as the parents of this universe.  He describes their state as being inseparable.  And as inseparable as the word and its meaning.  By drawing a comparison to the word and its meaning, kAlidAsa puts in a nutshell, the concept of creation.

In the vedic / tAntrik tradition of bhArat, the universe is said to have originated from nAda or pure sound. To understand mantras, it is necessary that we understand how this nAda is the cause of all creations and the place of origin of nAda in the human microcosm.

What is brahman? “bRhatvAt bRhmaNatvAt brahmetyabhidhIyate” meaning “due to its extensiveness and ability to expand it is known as brahma”. However, there is no expansion without contraction. It therefore follows that there is contraction also inherent. Therefore this vibration due to expansion and contraction leads to nAda which is brahman. In the human body nAda resides in the “anAhata cakra” in the hRdaya. This cakra is so called because the nAda originates without the coming together of two objects. It is common knowledge that striking one object against another produces noise. But in the anAhata cakra the nAda is produced without the striking of objects. Since no striking of objects is involved, the nAda so produced is eternal. Hence this eternal nAda is a shakti amsha. This pure, subtle sound or nAda without any form is known in tantric (shrIvidyA) parlance as “parA” and the nAda with form or rUpa is known as “pashyantI”. Further transformation (pariNAma) of this nAda is known as “MadhyamA” which further developes into “vaikharI” or audible sound. This transformation of the nAda brahman from parA vAk to vaikharI in four stages represents the transformation of sound in its purest form (parA) which is not audible and that which can be realized only by meditation by the practitioner (sAdhaka), to that which is audible and can be heard by every one (vaikharI).

This nAda brahma or parAshakti is described in the LalitA sahasranAma in the following verse:

ParA pratyakcitI rUpA pashyantI paradevatA |
madhyamA vaikharI rUpA bakta mAnasa hamsikA ||

Now, having discussed about the origin of nAda or pure subtle sound and its pariNAma or transformation from 'parA vAk' state or pure inaudible subtle nAda to 'vaikharI' or audible sound, the next logical question that arises is "Why Sanskrit for the mantras ?"

The nAda brahman which is all pervasive and which is the root cause for all creation, occurs as primal impulse in the human being in the mulAdhAra cakra as parA nAda. This parA nAda is considered as the origin of the 51 letters or varNa-s of sanskrit from 'a'kAra to 'ksha' kAra and therefore considered to originate from the parabrahman.

These 51 letters of sanskrit are therefore known as "akshara" or indestructible or imperishable as they are verily the expressions of the divine impulse. Each letter or varNa in itself is considered as the nAda brahman and hence they are known as mAtRkA akShara-s. mAtRkA here means originator, the mother. All mantras emerge from these mAtRkA akShara-s.

 
This is the reason why sanskrit is considered to be the mother of all languages.

The uniqueness of these mAtRkA akShara-s and therefore sanskrit is that these letters are completely phonetic; the name of each letter is the sound that it represents and has a distinct form. And therefore it follows that the sound represented by a combination of these letters or their units has a definite name and its visual form can be realised by repeatedly chanting the mantra.

Here, it would be prudent to know the definition of "mantra"                                    

mananAt tattva roopasya devasyAmitatejasaH
trAyate sarvabhayat tasmAnmantra itIritaH 

By meditating on the abundantly luminous true form of the mantra devatA, it protects from all fears. Therefore it is called as mantra. 

The word mantra is derived from the roots "man" to meditate and "trAi" to protect. Personification of the mantra devatA and experiencing the devatA chaitanya there is the aim of reciting the mantra. 

It should be understood that a particular mantra was conceived by a particular RShi who is called as mantra draShTA, i.e. who has visualised the deity or devatA corresponding to the mantra and who has realised that the chanting of certain combination of certain syllables will enable the devotee to visualise the devatA.

The chanting of mantras is also accordingly categorized as mAnasika, upAmshu & vAchika. mAnasika means chanting within oneself in the mind. upAmshu is the chanting where only the lips move but not audible. vAchika is the way of chanting which is audible to everyone. For obvious reasons, with due regard to this categorization, mAnasika form of chanting is the best, upAmshu is middling and vAchika not recommended.

Now coming to the scientific aspect of chanting, we know high frequency sound can even shatter an object, say a glass bowl. This much I think has been scientifically proved. It is not therefore difficult to associate and attribute frequency to the above three forms of chanting namely mAnasa, upAmshu and vAchika. These represent different frequencies.

Mantras are combination of syllables called as mAtrkAkShara-s which are fifty one in number. The RShi or Seer (mantra draShTA) of the mantra who has visualized the svarUpa (Visual form) of the devatA which is a form of energy with a particular frequency, has also visualized the combination of the syllables forming the mantra which corresponds to the frequency of that devatA. By chanting the mantra, it is possible to acquire unison with the mantra devatA i.e. it is possible to realize the devatA. Conversely, the mantras are spiritual formulas for acquiring the chaitanya (energy) of the devatA.

Since everything is experience based, any description or explantion will have its own limitations in conveying the exact purport. It is like understanding “If you touch fire, it will burn” which is purely theoretical knowledge! Touching fire and experiencing the heat alone is experiential knowledge.

We will see about the different types of mantras i.e their genders their use etc in the next part.
