Vaasanthi has beautiful tribute to Jayakanthan here:

Soon he was to overpower the literary scene of Tamil Nadu literally like a storm with short stories that revealed a deep and sensitive understanding of the downtrodden. For the first time here was a writer who did not just
portray their misery but found in the lives of rickshaw pullers, prostitutes, rowdies, pickpockets and cigarette-butt scavengers, a flaming passion, a liveliness, and truth. The compassion that entwined their characters and attitudes was so moving in his narration that the result was an elevating experience for the reader. He wrote about the slumdweller in earthy prose with firsthand knowledge of one who had lived among them in his early years of struggle when he worked as a compositor in a printing press. Suddenly it was a celebration of life, be it in dirt, squalor or a prostitute’s bed.

was also introduced to the works of the great Tamil poet Subramanya Bharati. Bharati has been Jayakanthan’s biggest inspiration to this day. There is no speech of his that is not interspersed with quotes from Bharati’s poetry. The passion with which the writer recites the quotes never fails to moisten the eyes of the listeners.
