Vyāsa said: From the thighs downward, Śiva’s body is described as the Agni-like (fiery, formidable) half; above that, it is the Soma-like (cool, auspicious) half. Some authorities also state that, in another reckoning, one half of his entire body is called “Agni” and the other half “Soma.” The passage frames Śiva as the union of opposing powers—terrible and beneficent—suggesting that cosmic order is sustained by balance rather than by one-sidedness.
व्यास उवाच
Śiva is portrayed as embodying both the fierce, consuming power of Agni and the cool, nurturing power of Soma; dharma and cosmic stability arise from the integration and right ordering of opposites rather than from exclusivity.
Vyāsa explains a doctrinal description of Śiva’s form, specifying a lower ‘Agni’ portion and an upper ‘Soma’ portion, while noting an alternate tradition that divides the whole body into Agni and Soma halves.
