The Mahabharata (c. 400 BCE–400 CE, with roots in older oral traditions): Traditionally attributed to the sage Vyasa (Krishna Dvaipayana Vyasa), though compiled and expanded collectively over centuries. This vast epic (over 100,000 verses) centers on the Kurukshetra War between the Pandavas and Kauravas, encompassing cosmology, philosophy, and the Bhagavad Gita. It functions as both history (itihasa) and moral encyclopedia, forming a bedrock of Hindu dharma, identity, and ethics.
The Ramayana (c. 300 BCE or earlier): Attributed to the sage Valmiki (regarded as Adi Kavi, or first poet). It narrates Prince Rama’s exile, the abduction of Sita, and the battle against Ravana, embodying ideals of duty (dharma), loyalty, and righteous kingship. Like the Mahabharata, it has shaped Hindu, Buddhist, and Southeast Asian cultures through countless retellings.
