Large crowds of supporters and opponents were on hand as the Dalai Lama visited Princeton University.
The Tibetan Buddhist spiritual leader stressed the importance of education and compassion during a talk Tuesday at the Ivy League school. He also urged his audience to more seriously consider the "oneness of humanity," instead of focusing too much on the differences between people.
A crowd estimated at about 4,300 people attended the lecture, which was held in the university's Jadwin gym.
Outside the event, hundreds of protesters gathered to show their opposition to the Dalai Lama. The group included members of the International Shugden Community, who claim the Dalai Lama has discriminated against them and improperly prevented them from freely and peacefully practicing their religion.
