Dravyasamgraha, often rendered as a “Compendium of Substances,” is a concise Jain philosophical treatise composed in Prakrit by Ācārya Nemicandra (also known as Nemicandra Siddhānta Cakravartin). It is traditionally dated to around the 10th century CE and is structured in brief, carefully crafted verses that lend themselves to memorization and commentary. The work is devoted to a systematic exposition of the six eternal substances (ṣaḍ-dravya) that, in Jain metaphysics, constitute the whole of reality. These are: jīva (soul or consciousness), pudgala (matter), dharma (the medium of motion), adharma (the medium of rest), ākāśa (space), and kāla (time). By organizing these categories with clarity and precision, the text offers a distilled map of existence as understood in the Jain tradition.

Its significance lies first in its doctrinal role as a foundational summary of Jain ontology. Dravyasamgraha gathers and condenses teachings found across earlier canonical and post-canonical works, presenting them in a coherent and ordered scheme that is accessible to both monastics and lay followers. Because it sets out what exists, how it exists, and how these substances relate to one another, it becomes an indispensable key for understanding central Jain doctrines such as the distinction between jīva and ajīva, the nature of karmic bondage, and the possibility of liberation (mokṣa). In this way, it does not merely catalogue metaphysical entities; it also lays the groundwork for grasping how the soul becomes entangled in matter and how that entanglement can be undone.

The text is also valued for the way it bridges philosophical theory and spiritual practice. By clarifying the structure of reality and the workings of karma, it illuminates why ethical discipline, meditation, and spiritual purification are not arbitrary rules but responses to the actual constitution of the universe and the soul. Students of Jain thought turn to Dravyasamgraha as a kind of compass, using its concise definitions and classifications to orient themselves on the path from ignorance and bondage toward self-realization and freedom from karmic accumulation. Its brevity, coupled with depth, has made it a standard textbook in Jain education and a touchstone for later commentators seeking to unpack its dense, suggestive verses.
