Please accept my blessings. I beg to thank you for your letter dated September 11th and the contribution check for the Bhakti-shastri examination. You have asked me for suggestions of what to say to different persons on Sankirtan Party, but there is no specific saying to any person. Whatever we say we say to everyone. It doesn't matter what is his age. Krishna Consciousness teaching does not depend on the age. It is the eternal platform of the soul. This is the meaning of transcendental; that is is beyond any consideration of material qualifications such as age or intelligence. Just like thunder in the sky does not need any explanation to any old person or to a young child, similarly, the transcendental sound vibration of Hare Krishna and preaching of Bhagavad Gita philosophy will act on everyone, regardless of whether or not they are understanding at first. When preaching you only repeat what you have heard from the disciplic succession and this will act.
Please offer my blessings to the others. I hope this will meet you in good health.
