Did Halley's Comet Appeared on the Night of Mahavira's Nirvana?

Summary

The article "Did Halley's Comet Appeared on the Night of Mahavira's Nirvana?" by P.C. Chopra investigates whether the famous Halley’s comet was the brilliant comet mentioned in Jain tradition as appearing on the night of Mahavira’s nirvana (liberation). After opening with a Shakespearean adage about comets and princes, Chopra reviews references to the comet in Jain scriptures such as the Kalpa Sutra and Bank Culi, noting that these texts describe a comet called Bhasma Rasi Graha that appeared when Lord Mahavira attained nirvana on Kartik Krishna Amavasya in 526 B.C. The author contrasts this Jaina account with similar stories in other texts and explores why later scholars overlooked the event. A detailed explanation of what comets are, their orbital characteristics, and the specific history of Halley’s comet sets the astronomical background. Chopra provides a table of calculated and historically observed apparitions of Halley’s comet over the last 2 500 years and discusses why the comet's calculated perihelion date can differ from its visibility from Earth because of Earth’s orbit, the comet’s inclined orbit and gravitational perturbations. Citing the Kalpa Sutra and related Agama literature, the article examines the mythic terms Bhasma Rasi Graha and Bhasma Graha, arguing that references to a comet in these texts likely refer to Halley’s comet. The author points out that ancient lists of “grahas” (planets) often included comets and explains the confusion among names in Jain scriptures. Chopra analyses the Kalpa Sutra description of the birth constellation and the timing of Mahavira’s nirvana to calculate when the comet would have been visible in the night sky. He also notes the coincidence of meteor showers (Orionids) that occur when Earth crosses Halley’s comet’s orbit, linking these showers with descriptions of “divine light” and fireworks in Jain festival traditions of Dipavali. The article argues that the spectacular display of a comet with a long tail lighting up the moonless night of 526 B.C. was Halley’s comet, making the event the origin of the Jain Vir Nirvan Samvat calendar. Chopra concludes that the popular expectation of Halley’s comet’s return in 1986, after a 76‑year orbital period, recalls its historic association with Mahavira’s nirvana and vindicates the accuracy of ancient Jain texts.
