The most spiritually charged site in Kurukshetra — and the essential stop on any itinerary — Jyotisar lies about five kilometres west of the town centre. The name means "Light of the Soul." Tradition holds that on this ground, with the two armies arrayed and Arjuna paralysed by doubt, Krishna revealed to him the teachings that became the Bhagavad Gita. A large Vishnu temple, a riverside ghat, and the ancient banyan tree (garlanded and tended daily) mark the spot. A modern chariot sculpture with a statue of Vishnu-as-Krishna above it stands at the entrance.
The site is most alive in the evenings, when a sound-and-light show dramatises the Mahabharata story against the backdrop of the plain and the sacred banyan — check timings locally as they vary by season. During the day the ghat is quiet and contemplative. Even visitors with no particular connection to the Mahabharata find the setting — flat agricultural plain, a sacred tree, the sense of enormous time — affecting. Allow at least an hour. Auto-rickshaws and tuk-tuks run from the town centre; negotiate the fare in advance.
