The Ramayana is one of the great Hindu epics. It is ascribed to the Hindu sage Valmiki and forms an important part of the Hindu literature (smṛti), considered to be itihāasa.The Ramayana is one of the two great epics of Hinduism, the other being the Mahabharata. It depicts the duties of relationships, portraying ideal characters like the ideal father, the ideal servant, the ideal brother, the ideal wife, and the ideal king. The name Ramayana is a tatpurusha compound of Rāma and ayana ("going, advancing"), translating to "Rama's Journey". The Ramayana consists of 24,000 verses in seven books (kāṇḍas) and 500 cantos (sargas), and tells the story of Rama (an avatar of the Hindu supreme-god Vishnu), whose wife Sita is abducted by Ravana, the king of Lanka (current day Sri Lanka). Incidentally the first letter of every 1000 verses (total 24) make the Gayatri mantra. Thematically, the Ramayana explores human values and the concept of dharma.
