The Ashtavasus in Temple Art: Soma, the Lunar Vasu, and His Sculptural Significance
The Ashtavasus are a group of eight divine beings who occupy
a significant place in the cosmic hierarchy of Hindu sacred tradition. The word
Vasu itself means "one who is bright" or "one who bestows
excellence," pointing to their nature as radiant, life-sustaining cosmic
forces. They are counted among the principal categories of devas, appearing in
the Vedas as attendants of Indra and later, in the Puranic tradition, as
offspring of Dharma and Aditi or, in some accounts, of Kashyapa. Their eight
names are Apah, Dhruva, Soma, Dhara, Anila, Anala or Agni, Pratyusha, and
Prabhasa, each presiding over a distinct natural and cosmic principle — water,
the pole star, the moon, earth, wind, fire, the dawn light, and the radiance of
the sky.
Together, they represent the fundamental forces that sustain
the universe in order and rhythm. Their worship and iconographic representation
form part of a deeply layered theological vision in which the divine is not
separate from nature but is its very substance.
Rarity and Significance of Ashtavasu Sculptures
Sculptural representations of the Ashtavasus are among the
rarer iconographic programs in Hindu temple art. While temples across India
dedicate elaborate panels to the Ashtadikpalas, the Navagrahas, and the
Saptamatrikas, the Ashtavasus appear in far fewer sacred complexes. This rarity
makes the examples that do survive all the more precious as windows into an
older and less frequently interpreted layer of Agamic and Shilpashastric
tradition.
The most celebrated extant sculptures of the Ashtavasus are
found in the Amritaghatesvarar Temple at Tirukkadadaiyur in Tamil Nadu. This
Shiva temple, famed for its connection to the episode of Markandeya and the
conquest of death, carries within its walls an iconographic program of great
depth and completeness. The Ashtavasu sculptures here stand as testimony to the
sophistication of the Chola and later Dravidian traditions of sacred
image-making.
The Textual Foundation: Vishwakarma Shilpa
The forms and attributes of the Ashtavasus are codified in
the Vishwakarma Shilpa, a canonical text of the Shilpashastra tradition
attributed to the divine architect Vishwakarma. This text prescribes in precise
detail the posture, ornamentation, hand gestures, weapons, and symbolic objects
that each of the eight Vasus must carry, ensuring that the sacred image
functions not merely as decoration but as a precise theological statement in
stone.
The Ashtavasus are prescribed as exclusively male in form.
Their appearance carries certain shared features that distinguish them from the
gentler classes of divine beings: protruding teeth, fiercely arched or sinuous
brows, hair blazing like flame, and an overall expression of terrifying
intensity. These are not accidental aesthetic choices. They reflect the Vasus'
nature as raw cosmic powers, forces of nature that are benevolent but not tame,
sustaining but not domesticated. The terrifying aspect in Hindu sacred art,
known as the ugra or raudra mode, signals that the deity being depicted
operates at the foundational level of reality, beyond human comfort or
comprehension.
Soma Among the Eight: The Lunar Vasu
Among the eight, Soma holds a uniquely luminous position.
Soma is the moon, and in the Vedic understanding the moon is not merely a
celestial body but a living reservoir of divine nectar, the amrita that
sustains the devas, the ancestors, and all of mortal life. The Rigveda exalts
Soma both as the plant whose pressed juice was the supreme sacred offering and
as the cosmic lunar principle that governs cycles of time, fertility, and the
subtle mind. The Shatapatha Brahmana describes Soma as the king of plants and
the lord of the ancestral realm, the one through whom the sacred offerings to
the pitrs are transmitted.
In the Bhagavad Gita, Bhagavan Krishna declares:
"I become Soma and nourish all plants."
(Bhagavad Gita, Chapter 15, Verse 13)
This statement directly invests the figure of Soma with a
cosmic nurturing function, linking the moon's sustaining light to the very act
of divine self-disclosure in the world. Soma as a Vasu thus embodies one of the
eight pillars of universal sustenance.
Iconographic Description of Soma
The sculptural form of Soma as prescribed and executed
follows a specific iconographic program. Soma is depicted seated in sukhasana,
the comfortable or easy posture, with legs gently crossed. This seated posture
conveys a quality of contemplative ease and celestial poise, appropriate to the
cool, reflective nature of the lunar deity.
He is adorned with divya abharana, the full set of divine
ornaments, which include the crown, earrings, armlets, bracelets, necklaces,
and the sacred thread, all rendered with meticulous detail by the shilpi, the
temple sculptor. His four arms carry four specific attributes: the mukta mala
or pearl garland, symbolic of the moon's white luminosity and the purity of
celestial grace; the shakti or a form of divine power, signifying that the moon
is not merely gentle but is a force of great cosmic potency; the padma or
lotus, pointing to spiritual unfoldment, purity emerging from the waters, and
the blossoming of the mind in clarity; and the ankusha or goad, a symbol of the
power to guide, restrain, and direct energies, reminding the devotee that the
mind ruled by the moon must ultimately be brought under the discipline of
higher wisdom.
It is worth noting that depending on the architectural
position of the sculpture within the temple wall, Soma and the other Vasus may
be depicted either seated or standing. This flexibility reflects the practical
demands of temple design while the essential iconographic attributes remain
constant.
Symbolism and Philosophical Meaning
Each element of Soma's form carries layered meaning rooted
in Vedic and Agamic philosophy. The pearl garland connects to the ancient
association of the moon with pearls, both born of water and both reflecting
light rather than generating it, symbolizing the reflective, receptive nature
of the purified mind. The lotus reminds the devotee that even in the midst of
the watery, emotional realm that the moon governs, the seeker can rise in
purity and open toward the light of consciousness. The ankusha speaks of the
need to govern the wandering mind, for the moon in Hindu philosophical
tradition is identified with the manas, the lower mind that fluctuates with
emotion, desire, and memory.
The fierce shared features of the Ashtavasus, including
Soma, remind the worshipper that these are not mere aesthetic embellishments.
They teach that even the gentle moon, giver of coolness and nectar, is
ultimately a power of the cosmos that demands reverence and cannot be reduced
to sentimentality.
Relevance in Contemporary Art and Devotion
In contemporary Hindu sacred art, the Ashtavasus remain an
underexplored but increasingly recognized subject. As temple restoration
projects across Tamil Nadu and Andhra Pradesh undertake the documentation and
revival of classical sculptural programs, the Ashtavasus are receiving renewed
scholarly and artistic attention. For modern artists working within the
Shilpashastra tradition, the Ashtavasu panels offer both a technical challenge
and a devotional discipline, requiring mastery of the ugra aesthetic alongside
the codes of divine ornamentation.
For the devotee and the student of Hindu thought alike, the image of Soma seated in the cool dignity of sukhasana, adorned with pearls and lotus, wielding both power and grace, is a meditation in stone on the nature of the universe itself.
