Uppalavanna was a Buddhist bhikkhuni, or nun, who was considered one of the top female disciples of the Buddha. She is considered the second of the Buddha's two chief female disciples, along with Khema. She was given the name Uppalavanna, meaning "color of a blue water lily", at birth due to the bluish color of her skin.

Śāriputra was one of the top disciples of the Buddha. He is considered the first of the Buddha's two chief male disciples, together with Maudgalyāyana. Śāriputra had a key leadership role in the ministry of the Buddha and is considered in many Buddhist schools to have been important in the development of the Buddhist Abhidharma. He frequently appears in Mahayana sutras, and in some sutras, is used as a counterpoint to represent the Hinayana school of Buddhism.
