Aştamūrti refers to the theological concept of Lord Śiva’s Eight Bodies, which systematically expounds His divine cosmic nature.
Preserved within Section II of the Linga Purana, the principle of Aştamūrti illustrates how the supreme Śiva principle encompasses all fundamental elements and cosmic manifestations alongside the Five Brahmans.
It forms a core foundation of Shaiva philosophy and liturgical practices, characterising the omnipresence of Śiva throughout the universe and framing the rituals associated with His worship, Linga consecration, and spiritual liberation.
