We have been spreading this sankirtana movement in the Western countries, and in our recent tour of European cities like Rome, Geneva, Paris and Frankfurt, many learned Christian scholars, priests, philosophers and yogis came to see us, and by the grace of Krsna they agreed that this Krsna consciousness movement, the bhakti cult, offers the topmost conclusion. Following in the footsteps of Sri Caitanya Mahaprabhu, we are trying to convince everyone that the devotional service of the Lord is enjoined in every scripture… It is not a question of being Christian, Mohammedan or Hindu. One should be purely religious and freed from all these material designations… This argument appeals to all intelligent men, and consequently this Krsna consciousness movement is gaining ground throughout the world. Due to our solid logic and scientific presentation, Sri Caitanya Mahaprabhu’s prediction that Krsna consciousness will spread in every town and village throughout the world is gradually being realized.
