Krishna, He killed so many demons, so in this age of demoniac tendency, we may not kill the demons like Krishna did it, but we can kill the demoniac tendency. How is that? By this Sankirtana weapon. That is the specific contribution by Lord Caitanya, Krishna Himself, in this Kali yuga. So I am informed that you are the Sankirtana leader for Laguna Beach temple, so you should very enthusiastically lead the Sankirtana party, and in this way you will very successfully kill the demoniac tendency of the rascals.
