“Being prayed for by the demigods, the Supreme Personality of Godhead, the Absolute Truth Himself, directly appeared with His expansion and expansions of the expansion. Their holy names were Rama, Lakshmana, Bharata and Shatrughna. These celebrated incarnations thus appeared in four forms as the sons of Maharaja Dasharatha.” (Shrimad Bhagavatam, 9.10.2)
