Srila Prabhupada departed from this world in Vrindavan dham, India, on the 14th of November 1977. One would not usually celebrate the disappearance day of a person, especially one so loved and revered as Srila Prabhupada. However, the departure of a pure Vaishnava gives cause for jubilation because he returns to his eternal service at Krishna’s lotus feet in Goloka Vrindavan, the spiritual world.
