When can bhikkhu teach meditation! What is the condition teach? Is it according their vassa? Is this specified in the suttas? Anumodana bhantes
I may be wrong, this is what I remember from various talks:
They receive the title “Ajahn” and are allowed to teach after being ordained for 10 years.
How often they actually get to teach is usually determined by the senior monk at the monastery. Though, generally, all monks are asked to teach every so often.
If they’re good at it, the abbot may send them off to start their own monastery.
