When I was in Madison to take the Great Insight teachings, the great commentary on the path to enlightenment; one day after the teaching, there were a lot of ants on the road next to the car that Roger had brought. I told the students that we have been like that. In our past lives we have been like that. So these insects are a teaching for us, to practice Dharma. They are born due to negative karma; due to not having practiced Dharma. They are showing this to us.
