ISKCON (International Society for Krishna Consciousness) is a modern movement within Sanātana Dharma, founded in 1966 by A.C. Bhaktivedanta Swami Prabhupāda. It follows the Gaudiya Vaishnavism tradition, which focuses on devotion to Lord Krishna as the Supreme God. ISKCON promotes chanting the Hare Krishna mantra, studying scriptures like the Bhagavad Gita and Srimad Bhagavatam, and living a life of devotion and service.
While Sanātana Dharma is a broad spiritual framework encompassing various philosophies and deities, ISKCON is a specific sect within it, centered on Krishna bhakti (devotion to Krishna).
