Ilāvṛta (or Ilāvṛta-varṣa) is the central and most sacred land division (varṣa) of Jambudvīpa within ancient Hindu, Jain, and Buddhist cosmological treatises, including the Bhāgavata Purāṇa, Viṣṇu Purāṇa, and the Mahābhārata. Situated at the literal heart of the world, Ilāvṛta directly encompasses Mount Meru (Sumeru)—the divine axis mundi of the cosmos.
According to Puranic mythology, Ilāvṛta is the exclusive abode of Lord Śiva (Śaṅkara), who dwells there in perpetual meditation accompanied by Goddess Bhavānī and her celestial maiden attendants. Mythological tradition holds that no other male entity is permitted to enter this sanctified realm; any male crossing into Ilāvṛta is instantly transformed into a female by a divine decree. Characterised by golden terrain, streams of heavenly nectar, and eternal spiritual harmony, Ilāvṛta acts as the ultimate physical and metaphysical bridge between the mortal realm of Earth and the higher celestial dimensions.
