You have mentioned that you have been invited to attend some "World Brotherhood Conference,'' and if it is convenient, you may go there with your Sankirtana Party, chant Hare Krishna, give some talk on Bhagavad-gita As It Is, and distribute Prasadam. That is our only business, and we can do these activities anywhere; it doesn't matter on the street or in some "World Brotherhood Conference."
(From Srila Prabhupada's letter to: Jayapataka — Los Angeles 1 August, 1969)
