The plot of "Chandala Bhikshuki" is based on the divine incarnation story of Sri Buddha, where Matangi, a Chandala (outcast) woman, gains entry into the congregation. In the preface of "Chandala Bhikshuki," Ulloor mentions that the struggles and this story are like two flowers blooming on the same stalk. The idea of incorporating themes related to Buddhism in this work likely stemmed from the belief that many Buddhist principles could help eradicate the injustices in Hindu practices. The story for this poem was inspired by Professor Lakshminarasu's book "The Essence of Buddhism."
