After a month spent delivering discourses to Sri Lankans who had ventured to the capital, Mahinda retreated to Mihintale to spend the vassa during the monsoon season. As a result, a second royal funded monastery was built there. Later, Mahinda organised for a stupa to be constructed, and a part of the bodily relics of Gautama Buddha were transferred from the Maurya Empire to Sri Lanka. Mahinda then had Arittha, Devanampiyatissa's nephew, a bhikkhu, expound the Vinaya monastic code of discipline to further Buddhism in Sri Lanka.
