Regarding your proposed festivals, yes, that is a good idea. Please do it very nicely. These public festivals have proven very effective in spreading knowledge about Krishna Consciousness to all the citizens. In fact, I have directed the GBC to organize such festivals and travelling sankirtana throughout their zones. The festival we are holding at present in Delhi has been extremely successful, and by Krishna's grace everyone is appreciating this Movement by seeing the beautiful deity worship, by hearing the melodious kirtana, and by seeing the bright faces of my students.
