The Value of Ghaṭikā in the Bhāgavata Purāṇa: A Study of Purāṇic Time Measurement
摘要
Concerning the various units of time represented in the Śrīmad-Bhāgavatam (SB), the ghaṭikā has been described in intricate detail. Deriving the values of other time units stated therein depends upon ascertaining the value of the ghaṭikā. This paper examines that description through linguistic analysis and tabulated experimental observations. Original English translations of Sanskrit and Bengali commentaries on relevant SB verses, drawn from twelve esteemed ācāryas, offer valuable insight into both the nuanced usage of Sanskrit and the scientific temperament of these commentators. It is noteworthy that commentators on the Bhāgavata Purāṇa attribute a contextual polyvalence to the ghaṭikā, suggesting values of both 24 min and 30 min. The study does not seek to adjudicate between these conventions; rather, it documents the evidence for their coexistence and considers its implications for metrological clarity in Bhāgavata studies. It further notes that making unit assumptions explicit can be useful in discussions of purāṇa-jyotiṣaśāstrayor bhūgola-khagola virodha-parihāra (the reconciliation of apparent contradictions between Purāṇic and Jyotiṣa accounts of the terrestrial and celestial spheres), where apparent mismatches sometimes arise from differing conventions rather than substantive disagreement. More broadly, the study has significance for Hindu Studies and Indian Knowledge Systems, since it shows how Purāṇic theology, textual exegesis, quantitative reasoning, and experimental reconstruction may be brought into a common interpretive framework. It thereby highlights that Hindu cosmological discourse is not divorced from questions of measurement, scientific reasoning, or material practice. It is hoped that establishing a clear, reproducible framework for these units may assist future work in assessing such issues more precisely.
