The Science of Clouds in Ancient Jain Literature

K.G. Sheshadri explores meteorological concepts preserved in ancient Indian literature, with a particular focus on Jain sources. The introduction explains that clouds—collections of ice crystals and water droplets—have long fascinated observers and that their shapes and colours were used for rainfall prediction. The author surveys Vedic and post‑Vedic texts, noting that the Rigveda contains detailed descriptions of the hydrological cycle: the Sun draws up waters that are later released as rain by the gods Agni (fire) and Parjanya (rain). The Yajurveda describes cloud seeding in the Kārīrā sacrifice, where smoke from burning Kārīrā fruits aids rainfall. The Brahmāṇḍa Purāṇa classifies clouds into three types—Agneya (fire‑born), Brahmaja (born of Brahmā) and Varuṇaja (water‑born)—and further describes their colours, shapes and associations. Sheshadri then turns to Jain literature, suggesting that Jain scriptures also contain sophisticated observations about clouds. Although the article relies more on comparative Indian sources than on specific Jain canonical passages, it implies that Jain scholars participated in a broader intellectual tradition that linked meteorological phenomena to cosmology and ritual. By examining descriptions of clouds and rainfall processes across Sanskrit literature, the author illustrates how ancient Indians integrated empirical observations with mythic narratives. The essay situates these ideas in the wider context of ancient Indian science, where astronomy, meteorology and ritual were interwoven. Sheshadri suggests that such texts provided practical knowledge for agriculture and environmental planning, demonstrating that religious literature also served scientific ends.
