Sects & Sectarianism - Bhikkhu Sujato - Bog

Are the differences just cultural, or do they have fundamentally different visions of Dhamma?

If we are to understand the differences, and sometimes tensions, between the schools of Buddhism today, we must examine more closely the forces that spurred their formation.
