The International Society for Krishna Consciousness (ISKCON), known colloquially as the Hare Krishna movement, is a Gaudiya Vaishnava religious organization. It was founded in 1966 in New York City by "His Divine Grace" Abhay Caranaravinda Bhaktivedanta Svami "Prabhupada". Its core beliefs are based on traditional Hindu scriptures such as the Śrīmad Bhāgavatam and the Bhagavad-gītā, both of which, according to the traditional Hindu view, date back more than 5,000 years. The distinctive appearance of the movement and its culture come from the Gaudiya Vaisnava tradition, which has had adherents in India since the late 15th century and Western converts since the early 1930s.

ISKCON was formed to spread the practice of bhakti yoga, in which aspirant devotees (bhaktas) dedicate their thoughts and actions towards pleasing the Supreme Lord, Krishna. ISKCON today is a worldwide confederation of more than 400 centers, including 60 farm communities, some aiming for self-sufficiency, 50 schools and 90 restaurants. In recent decades the movement's most rapid expansions in terms of numbers of membership have been within Eastern Europe (especially since the collapse of the Soviet Union) and India.

Sacinandana Swami first came in contact with Gaudiya Vaishnavism after seeing Hare Krishna devotees on German TV in the late 1960s. "One day, I remember it was in television. I was a fan of the Rolling Stones. One of the members, the guitarist, had died from an overdose of drugs. I cried tears - my model had died. After this, an exciting new group, the Radha Krishna Temple, came on and sang the Hare Krishna mantra. I immediately felt deep solace."
