Dhammapada Verse 75
The Story of Samanera Tissa of the Forest Monastery
Tissa was the son of a rich man from Savatthi. His father used to offer alms-food to the Chief Disciple Sariputta in their house and so Tissa even as a child had met the Chief Disciple on many occasions. At the age of seven he became a novice (samanera) under the Chief Disciple Sariputta. While he was staying at the Jetavana monastery, many of his friends and relatives came to see him, bringing presents and offerings. The samanera found these visits to be very tiresome; so after taking a subject of meditation from the Buddha, he left for a forest monastery. Whenever a villager offered him anything, Tissa would just say 'May you be happy, may you be liberated from the ills of life,' ("Sukhita hotha, dukkha muccatha"), and would go on his own way. While he stayed at the forest monastery, he ardently and diligently practiced meditation, and at the end of three months he attained arahatship.
