In a July 8, 1970 letter to Sridama prabhu, His Divine Grace, A.C. Bhaktivedanta Swami Srila Prabhupada wrote:
“The daily regulative duties must be performed by everyone very strictly, the beads chanted sixteen rounds, and our literatures read and discussed. In this way everything should be done very nicely. Sankirtana should be done by you in the streets and at gatherings and in this manner display what is this Krishna consciousness movement and how it is for everyone’s eternal welfare and happiness.
So you do all these with great enthusiasm and very carefully. Our all activities must be open so that no one may criticize our mission, so all dealing must be to the standard of Vaisnavism. We cannot misrepresent ourselves for the purpose of taking monies from the public, but as everything is undertaken forthrightly in Krishna consciousness way, then Lord Krishna will be pleased to provide all facilities for aiding our such sincere service.”
