The rains retreat of the monks ends on the full moon day of October. During this Vassana retreat that lasts for 3 months, the monks would have served the community of followers in various ways such as giving sermons, teaching Dhamma and meditation, counseling and serving in many other ways. After this rains retreat the monks are free to leave the place where the retreat was held.

Before they leave, it is the custom of the devotees to hold a farewell ceremony for the monks. This is called the Kathina Ceremony or robes giving ceremony. During this ceremony many gifts are offered to the monks for their use as well as for the upkeep of the monastery.
