The approach is to persuade people to have faith in the way of the Buddha that is to be without evil speech without evil actions as the Buddha instructed his followers in the Ovadapatimokkha. In other words, missionary monks must go about their work peacefully,even in situations which would normally incite violence. They mist have the highest degree of tolerance and segregating. The Buddha encouraged his monks to have the virtue of tolerance, as with the following story of punna Bhikkhu.
