This painting is located on the left side of the barrel-vaulted ceiling in the main chamber. According to the Avadanasataka, Purnabhadra was a kind and compassionate brahmin engaged in much charity. One day, when the Buddha was teaching the Dharma at Venuvana Monastery, Purnabhadra invited him to his home. Purnabhadra gave his offerings to the Buddha, and with the merit from his kindness, was on the path to attaining Buddhahood.
In this painting, the Buddha wears a dark brown robe, and has a circular nimbus and aureole. He holds a bowl in his right hand and is seated on a rectangular throne with legs crossed at the ankles. Purnabhadra, in merchant attire, is depicted in front of the Buddha. He looks up at the Buddha in earnest and raises both his hands as if bestowing alms.
