Step 1: Anchor the description around a real institution.
Nalanda is the clearest example to describe the system through, since detailed historical records of it survive.
Step 2: Describe the entry point.
A student joined by taking ordination as a novice monk, accepting the monastery's rules of discipline and simple living from the start.
Step 3: Describe what and how they studied.
Study covered Buddhist philosophy and scripture at the core, with logic, medicine, and other secular subjects added at larger centres, taught through oral teaching and open debate between teacher and student.
Step 4: Describe its wider reach.
Because places like Nalanda were funded by donations and open to able students regardless of background, they drew learners from far beyond India, making Buddhist education one of the earliest globally connected systems.
Final Answer:
Centred on monasteries like Nalanda, Buddhist education combined disciplined monastic life, oral guru-shishya teaching, a mixed religious-and-secular syllabus, and wide international reach.
