2. Mahasena. A brahmin, friend of Vanganta, father of Sariputta. He was poor, and, out of compassion for him, Sariputta came to his house for alms. Twice Mahasena hid himself, having nothing to give, but, one day, receiving a bowl of rice porridge and a small piece of cloth, he thought of Sariputta. The Elder had just risen from a trance, and, becoming aware of Mahasenas desire, he visited him, and was given the porridge and the piece of cloth with a prayer from Mahasena, May I realize the Truth you have seen. After death, Mahasena was born as the novice and was called Vanavasi Tissa. DhA.ii.84.
3. Mahasena. Younger son of King Gothabhaya. He became king of Ceylon (334-361 A.C.), and under the advice of his teacher Sanghamitta and his minister Sona, he despoiled Mahavihara and enriched Abhayagiri. He issued a decree that no one should give alms to the monks of Mahavihara. But, later, his friend and minister, Meghavannabhaya, convinced him of his error, and he became a supporter of Mahavihara. Soon after, however, he fell under the influence of a monk, named Tissa, and built Jetavanavihara in the precincts of Mahavihara, despite the protests of the monks. Tissa was later expelled from the Order. The king built the Manihira, Gokanna, Erakavilla, Kalandagama, Migagama, Gangasenakapabbata, Dhatusenapabbata, Kokavata, Ruparama, and Hulapitthi viharas and two nunneries Uttara and Abhaya.
