King Dasharatha had granted his wife Kaikeyi two boons years earlier; she cashes them in to demand her son Bharata be crowned and Rama exiled for fourteen years, and Rama accepts banishment without protest to keep his father's word binding. Bharata then refuses the throne he was given, placing Rama's sandals on it to rule as regent until Rama returns. The promise is honored even when honoring it serves no one's happiness and the beneficiary rejects the benefit.
The epic argues that obligation to one's role (dharma) should govern action even when it costs the actor the throne, comfort, or desire, because the integrity of the social order depends on individuals honoring commitments regardless of consequence to themselves. Rama forfeits a kingdom rather than let his father break a vow. The book frames this choice not as tragic error but as the defining virtue that makes a person worthy of rule.
Ravana cannot take Sita by force while Rama guards her, so he sends the demon Maricha disguised as a golden deer to draw Rama away, then appears as a wandering holy man to breach the trust Sita extends to a seeming ascetic. The defense is defeated not by overpowering the guardian but by exploiting the virtue (hospitality, compassion) of the guarded.
After Sita is rescued, she is made to prove her chastity by entering fire, and later recalled to prove it again before the people, though she was the victim and committed no wrong. Viewing conduct through the lens of public reputation rather than personal innocence, the one who suffered harm is burdened with demonstrating purity, while the one who did harm faced only battle.
