The best time and place is Mayapur on Lord Caitanya's Appearance Day. That is not only the best for me but for everyone. Mayapur is meant for that. If possible all devotees from all our centers should go for 8 days at that time.” – Srila Prabhupada, Letter to Tamal Krishna, Bhaktivedanta Manor 20 July, 1973
