Jayamaṅgalā and the other Commentaries on Sāṃkhya‑saptati

Summary

The Sāṃkhya‑saptati is a concise treatise of seventy verses attributed to Īśvarakṛṣṇa that summarises Sāṃkhya philosophy. This article examines the various commentaries on the text, focusing particularly on the Jayamaṅgalā commentary and comparing it with other expositions. The author begins by outlining the core doctrines of Sāṃkhya: the dualism between unchanging consciousness (puruṣa) and primordial matter (prakṛti), the enumeration of twenty‑four tattvas, the theory of evolution through successive manifestations, and the path to liberation through discriminative knowledge. He then reviews the historical context of the Sāṃkhya‑saptati and notes its influence on later commentators. The Jayamaṅgalā, often attributed to Śrīdhara, is praised for its clarity and concision. The article analyses how this commentary interprets key verses, particularly those dealing with the emergence of the intellect (buddhi), ego (ahaṃkāra) and the senses, and how it resolves apparent contradictions in the original text. Comparisons are drawn with other commentaries such as the Māṭhara‑vṛtti and the Yuktidīpikā. The author discusses scholarly debates over the dates and authorship of these works and points out doctrinal differences, such as whether the gunas are independent substances or modes of prakṛti. Attention is given to linguistic variations and textual variants found in different manuscripts. By juxtaposing the Jayamaṅgalā’s explanations with those of its rivals, the article demonstrates how commentators sought to integrate Sāṃkhya with Yoga and Vedānta while defending its autonomy. The final section assesses the influence of these commentaries on medieval Hindu thought and highlights their importance for understanding the transmission of Sāṃkhya philosophy.
