Śivasaṃhitā 2.1

The Śivasaṃhitā opens its cosmological chapter with a striking declaration: the entire universe is contained within the human body. Mount Meru, the cosmic axis of Hindu and Buddhist cosmology, is here identified with the vertebral column. This is not poetic metaphor but a functional map — the body is the very laboratory through which all creation operates.

The chapter heading tattvajñānopadeśa — instruction in the knowledge of principles — signals the text’s ambition. The saptadvīpa, or seven island-continents of Purāṇic geography, find their correspondence in subtle regions and centers of the body, inviting practitioners to reread sacred cosmological literature as interior anatomy.

This microcosm-macrocosm doctrine, encapsulated in the formula piṇḍe yad brahmaṇḍe (what is in the body is in the universe), is foundational to Tantric Haṭhayoga. Parallel teachings appear in the Kubjikāmatatantra and later in the Ṣaṭcakranirūpaṇa. For the practitioner, this reframes every physical discipline as a cosmological act — to work the body is to engage the entire created order.
