The Sangha Must (and always has) Adapted to a Changing Society

To insist upon preserving traditional institutions irrespective of circumstances would be to indulge in a dinosaur mentality. The question of survival depends essentially on the structure of the sangha, for the sangha is the communal expression of the Buddhist experience that needs to be rooted in the soil of society as a whole. As such it draws its sustenance from beyond its own immediate boundaries; but if its root structure demands a soil that no longer exists, it will inevitably wither and die.
