Jayapataka Swami: The madhyama adhikari see people in four levels. They see the Supreme Lord and His pure devotees, in a respectful mood. They see the devotees who are peers, in equal level, they try to associate with them. Then they see the innocent people who are pious, and they try to preach or encourage them to chant Hare Krsna. And they see the atheists, people who have materialistic qualities, and try to avoid them. So, if something is used in the service of the Lord, it is spiritual. Everything else is basically material. But in that there is the innocent and then there is the atheistically demonic. So we want to preach to the innocent, and we avoid the atheistic demons. Hare Krsna!
