After seeing two birds being shot, Vālmīki creates a new form of meter called śloka, and then is granted the ability to compose an epic poem about Rāma.

He teaches his poem to the boys Lava and Kuśa, who recite it throughout the land and eventually at the court of king Rāma, which then begins the main narrative.

Meanwhile the gods have petitioned to Brahmā and Viṣṇu about Rāvaṇa, a rākṣasa who has been oppressing rṣis, yakṣas, gandharvas, asuras, and brāhmaṇas.

After distributing the porridge, Daśaratha's wives Kausalyā, Kaikeyī, and Sumitrā bear Rāma, Bharata, and the twins Lakṣmaṇa and Śatrughna respectively.

Daśaratha, who is initially reluctant to part with his dearest son, is eventually convinced to send Rāma with Viśvāmitra, along with Lakṣmaṇa.

[3] Once the group reaches Mithilā, a minister in Janaka’s court narrates the life of Viśvāmitra, and his journey from king to brahman-seer (“brahmarṣi”).
