Markandeya begins to answer Yudhishthira's request by tracing the lineage of Rama from the Ikshvaku king Aja through Dasharatha and his four sons. Then he turns to Ravana's birth, describing how the god Prajapati's line passed through Pulastya, and how a father's anger created the sage Vishrava — the father of the rakshasa king.
