We have got a great mission. You are one of the strong pillars of the mission. So I have all confidence in you. Follow strictly all our rules and regulations. Be fully strong to push on this cult amongst the educated scientific circle. That you are getting many speaking invitations is a good indication. Take advantage of this. Krsna is asking you to do this job. The people there are naturally Krsna conscious, and when you present more scientifically, then will be convinced.
