Opened in 1985, the Digambar Jain Trilok Shodh Sansthan – Digambar Jain Institute of Cosmographic Research – in Hastinapur, Uttar Pradesh, was founded by Āryikā Jñānamati. A centre of research into Jain cosmology, the institute publishes the Vira Jñānodaya Granthamālā series and the Samyagjñāna journal and also houses a boys’ boarding school. Several temples attract pilgrims but the main draw is the large 3-D model of Jambūdvīpa, complete with a 30-metre-tall Mount Meru.
